Please try again.", 101 + } 102 + tmpl.ExecuteTemplate(w, "login.html", data) 103 + ``` 104 + 105 + --- 106 + 107 + ## Template → Handler Contract 108 + 109 + ### Form Submission Contract 110 + 111 + **Form Element**: 112 + ```html 113 + <form method="POST" action="/auth/login"> 114 + <label for="handle">Bluesky Handle</label> 115 + <input type="text" 116 + id="handle" 117 + name="handle" 118 + placeholder="user.bsky.social" 119 + required 120 + value="{{.Handle}}"> 121 + <button type="submit">Login with Bluesky</button> 122 + </form> 123 + ``` 124 + 125 + **Required Attributes**: 126 + - `method="POST"` - Handler expects POST 127 + - `name="handle"` - Handler reads via `r.FormValue("handle")` 128 + - `required` - HTML5 client-side validation 129 + - `value="{{.Handle}}"` - Repopulate on error 130 + 131 + **Form Data Contract**: 132 + ``` 133 + Field Name: handle 134 + Type: string 135 + Required: yes 136 + Format: Bluesky handle (e.g., "user.bsky.social" or "user.com") 137 + Validation: Non-empty, valid handle format 138 + ``` 139 + 140 + --- 141 + 142 + ## Template Structure Contract 143 + 144 + ### Required Template Blocks 145 + 146 + The login template **MUST** implement these three blocks to work with the base layout: 147 + 148 + #### 1. Title Block 149 + ```html 150 + {{define "title"}}Login - Bluesky Archive{{end}} 151 + ``` 152 + 153 + **Purpose**: Sets `<title>` tag and may be used in page headers 154 + **Required**: Yes 155 + **Format**: Plain text, no HTML 156 + 157 + #### 2. Navigation Block 158 + ```html 159 + {{define "nav"}} 160 + <nav class="container"> 161 + <ul> 162 + <li><strong>Bluesky Archive</strong></li> 163 + </ul> 164 + <ul> 165 + <li><a href="/about">About</a></li> 166 + </ul> 167 + </nav> 168 + {{end}} 169 + ``` 170 + 171 + **Purpose**: Defines page navigation 172 + **Required**: Yes (can be minimal for login page) 173 + **Format**: HTML nav element with Pico CSS styling 174 + 175 + #### 3. Content Block 176 + ```html 177 + {{define "content"}} 178 + <section class="container"> 179 + <!-- Error display --> 180 + {{if .Error}} 181 + <article aria-label="Error"> 182 + <header><strong>Error</strong></header> 183 + <p>{{.Error}}</p> 184 + </article> 185 + {{end}} 186 + 187 + <!-- Login form --> 188 + <article> 189 + <header><strong>Login with Bluesky</strong></header> 190 + <form method="POST"> 191 + <!-- Form fields --> 192 + </form> 193 + </article> 194 + </section> 195 + {{end}} 196 + ``` 197 + 198 + **Purpose**: Main page content 199 + **Required**: Yes 200 + **Format**: HTML with Pico CSS classes 201 + 202 + --- 203 + 204 + ## Error Display Contract 205 + 206 + ### Error Message Format 207 + 208 + **Handler → Template**: 209 + ```go 210 + data.Error = "User-friendly error message" 211 + ``` 212 + 213 + **Template → User**: 214 + ```html 215 + {{if .Error}} 216 + <article aria-label="Error" style="background-color: var(--del-color); border-left: 4px solid #dc3545;"> 217 + <header><strong>Error</strong></header> 218 + <p>{{.Error}}</p> 219 + </article> 220 + {{end}} 221 + ``` 222 + 223 + **Error Message Guidelines**: 224 + 225 + ✅ **Good Error Messages** (user-friendly): 226 + - "Bluesky handle is required" 227 + - "Failed to connect to Bluesky. Please try again." 228 + - "Invalid handle format. Please use format: user.bsky.social" 229 + 230 + ❌ **Bad Error Messages** (internal details): 231 + - "panic: nil pointer dereference" 232 + - "OAuth client initialization failed: invalid config" 233 + - "database connection error: timeout" 234 + 235 + **Security Note**: Never expose internal system details, stack traces, or configuration in error messages. 236 + 237 + --- 238 + 239 + ## CSS Styling Contract 240 + 241 + ### Pico CSS Classes 242 + 243 + The template must use these Pico CSS classes for consistency: 244 + 245 + | Element | CSS Class | Purpose | 246 + |---------|-----------|---------| 247 + | Main container | `container` | Responsive centering and padding | 248 + | Navigation | `<nav class="container">` | Consistent navigation styling | 249 + | Error article | `<article aria-label="Error">` | Semantic error display | 250 + | Form fieldset | `<fieldset>` | Form grouping (optional) | 251 + | Input fields | (no class) | Pico CSS auto-styles inputs | 252 + | Buttons | (no class) | Pico CSS auto-styles buttons | 253 + | Help text | `<small>` | Muted help text | 254 + 255 + **Classless Styling**: Pico CSS automatically styles most HTML elements without requiring classes. Only use classes for containers and semantic elements. 256 + 257 + --- 258 + 259 + ## Validation Contract 260 + 261 + ### Client-Side Validation (HTML5) 262 + 263 + **Template Responsibility**: 264 + ```html 265 + <input type="text" name="handle" required> 266 + ``` 267 + 268 + - `required` attribute: Browser prevents empty submission 269 + - `type="text"`: Standard text input (no special validation) 270 + - `placeholder`: Provides format example 271 + 272 + **Browser Behavior**: 273 + - Prevents form submission if field is empty 274 + - Shows browser default error message 275 + - No JavaScript required 276 + 277 + ### Server-Side Validation (Handler) 278 + 279 + **Handler Responsibility**: 280 + ```go 281 + handle := r.FormValue("handle") 282 + if handle == "" { 283 + // Render template with error 284 + data.Error = "Bluesky handle is required" 285 + return 286 + } 287 + 288 + // Validate handle format 289 + if !isValidHandle(handle) { 290 + data.Error = "Invalid handle format" 291 + return 292 + } 293 + ``` 294 + 295 + **Validation Rules**: 296 + 1. Non-empty (redundant with HTML5, but required for security) 297 + 2. Valid handle format (domain name or subdomain.domain) 298 + 3. Reasonable length (< 255 characters) 299 + 300 + --- 301 + 302 + ## OAuth Flow Contract 303 + 304 + ### Successful OAuth Initiation 305 + 306 + **Handler Action**: 307 + ```go 308 + // Start OAuth flow 309 + flowState, err := om.client.StartAuthFlow(ctx, handle) 310 + if err != nil { 311 + // Return error via template 312 + return 313 + } 314 + 315 + // Redirect to Bluesky 316 + http.Redirect(w, r, flowState.AuthURL, http.StatusFound) 317 + ``` 318 + 319 + **Template Not Involved**: On success, handler redirects to Bluesky. Template is not rendered. 320 + 321 + ### OAuth Callback (Out of Scope) 322 + 323 + **Note**: The OAuth callback flow (`/auth/callback`) is **not** part of this feature. It remains unchanged and does not use the login template. 324 + 325 + --- 326 + 327 + ## Testing Contract 328 + 329 + ### Manual Testing Checklist 330 + 331 + **Visual Consistency**: 332 + - [ ] Login page matches design of export.html, dashboard.html 333 + - [ ] Pico CSS styling applied correctly 334 + - [ ] Responsive design works on mobile/tablet/desktop 335 + - [ ] Error messages display in red article with proper formatting 336 + 337 + **Functional Testing**: 338 + - [ ] Empty form submission shows HTML5 validation message 339 + - [ ] Valid handle initiates OAuth flow (redirect to Bluesky) 340 + - [ ] Invalid handle shows server-side error message 341 + - [ ] Error message displays with previously entered handle repopulated 342 + - [ ] Navigation links work correctly 343 + - [ ] Page loads in < 500ms 344 + 345 + **Security Testing**: 346 + - [ ] XSS attempt in handle field is escaped by template engine 347 + - [ ] Error messages don't expose internal details 348 + - [ ] OAuth flow initiates correctly (no CSRF vulnerability) 349 + 350 + --- 351 + 352 + ## Backward Compatibility 353 + 354 + ### Breaking Changes: None 355 + 356 + This feature is a **drop-in replacement** for the existing inline HTML: 357 + 358 + **Before** (inline HTML): 359 + ```go 360 + w.Write([]byte(`<html>...</html>`)) 361 + ``` 362 + 363 + **After** (template rendering): 364 + ```go 365 + tmpl.ExecuteTemplate(w, "login.html", data) 366 + ``` 367 + 368 + **User Experience**: Identical OAuth flow, same form fields, same POST endpoint. Only visual styling changes. 369 + 370 + **API Contract**: No API changes. Internal implementation detail only. 371 + 372 + --- 373 + 374 + ## Summary 375 + 376 + | Contract Element | Handler Responsibility | Template Responsibility | 377 + |-----------------|------------------------|-------------------------| 378 + | Data Structure | Provide LoginPageData | Render with {{.Field}} | 379 + | Error Display | Set .Error field | Show error if present | 380 + | Form Submission | Process POST /auth/login | Submit with name="handle" | 381 + | OAuth Flow | Redirect on success | N/A (not involved) | 382 + | Validation | Server-side validation | Client-side HTML5 required | 383 + | Styling | N/A (not involved) | Apply Pico CSS classes | 384 + | Navigation | N/A (not involved) | Define nav block | 385 + 386 + This contract ensures clean separation of concerns: handlers manage logic and data, templates manage presentation.

··· 1 + # Data Model: Login Form Template & Styling 2 + 3 + **Feature**: 006-login-template-styling 4 + **Date**: 2025-11-02 5 + **Status**: Complete 6 + 7 + ## Overview 8 + 9 + This feature is primarily a UI refactoring with minimal data modeling requirements. The only "data" involved is the template rendering data structure passed from the handler to the template. No database schema changes, no new persistent entities. 10 + 11 + ## Template Data Structure 12 + 13 + ### LoginPageData 14 + 15 + Represents the data passed to the login template for rendering. 16 + 17 + **Purpose**: Provide all necessary information for rendering the login page, including error messages and contextual information. 18 + 19 + **Fields**: 20 + 21 + | Field | Type | Required | Description | 22 + |-------|------|----------|-------------| 23 + | `Title` | `string` | Yes | Page title (e.g., "Login - Bluesky Archive") | 24 + | `Error` | `string` | No | Error message to display if login failed or validation error occurred | 25 + | `Message` | `string` | No | Informational message (rarely used for login page, but included for consistency) | 26 + | `Handle` | `string` | No | Pre-filled handle value (for repopulating form after validation error) | 27 + 28 + **Go Struct Definition**: 29 + 30 + ```go 31 + type LoginPageData struct { 32 + Title string 33 + Error string 34 + Message string 35 + Handle string 36 + } 37 + ``` 38 + 39 + **Usage Example**: 40 + 41 + ```go 42 + // Success case - show login form 43 + data := LoginPageData{ 44 + Title: "Login - Bluesky Archive", 45 + Error: "", 46 + Handle: "", 47 + } 48 + renderTemplate(w, "login.html", data) 49 + 50 + // Error case - validation failed 51 + data := LoginPageData{ 52 + Title: "Login - Bluesky Archive", 53 + Error: "Bluesky handle is required", 54 + Handle: r.FormValue("handle"), // Repopulate for user convenience 55 + } 56 + renderTemplate(w, "login.html", data) 57 + 58 + // OAuth initiation error 59 + data := LoginPageData{ 60 + Title: "Login - Bluesky Archive", 61 + Error: "Failed to connect to Bluesky. Please try again.", 62 + } 63 + renderTemplate(w, "login.html", data) 64 + ``` 65 + 66 + **Validation Rules**: 67 + 68 + - `Title`: Must not be empty 69 + - `Error`: Empty string when no error, non-empty descriptive message on error 70 + - `Message`: Typically empty for login page 71 + - `Handle`: Should be populated only when redisplaying form after error 72 + 73 + **State Transitions**: 74 + 75 + 1. **Initial Load**: `Error=""`, `Handle=""` → Display empty login form 76 + 2. **Validation Error**: `Error="..."`, `Handle="user_input"` → Display form with error and preserve user input 77 + 3. **OAuth Error**: `Error="..."`, `Handle=""` → Display form with error, clear handle 78 + 4. **Success**: Redirect to OAuth provider (no template rendering) 79 + 80 + --- 81 + 82 + ## Existing Data Models (No Changes) 83 + 84 + This feature does not modify any existing data models. The following existing models remain unchanged: 85 + 86 + ### OAuth Session Data (in `internal/auth/oauth.go`) 87 + 88 + **No Changes**: The OAuth flow state management remains identical. This feature only affects how the login form HTML is generated, not the OAuth logic itself. 89 + 90 + **Existing Implementation**: 91 + - `bskyoauth` library handles all OAuth state 92 + - Session management unchanged 93 + - Token storage unchanged 94 + 95 + --- 96 + 97 + ## No Database Schema Changes 98 + 99 + This feature requires **zero** database migrations or schema changes: 100 + 101 + - No new tables 102 + - No new columns 103 + - No new indexes 104 + - No data migration required 105 + 106 + **Rationale**: This is purely a presentation layer change. All data handling (OAuth tokens, sessions) remains unchanged. 107 + 108 + --- 109 + 110 + ## Data Flow 111 + 112 + ### Login Page Request Flow 113 + 114 + ``` 115 + 1. User requests /auth/login (GET) 116 + ↓ 117 + 2. Handler creates empty LoginPageData 118 + ↓ 119 + 3. Template renders with empty form 120 + ↓ 121 + 4. User submits handle (POST) 122 + ↓ 123 + 5a. Validation fails → Handler creates LoginPageData with Error 124 + ↓ 125 + Template renders with error message 126 + 127 + 5b. Validation passes → OAuth flow initiates 128 + ↓ 129 + Redirect to Bluesky (no template rendering) 130 + ``` 131 + 132 + ### Error Handling Flow 133 + 134 + ``` 135 + Client-side (HTML5): 136 + - Browser validates required field 137 + - Prevents submission if empty 138 + 139 + Server-side: 140 + - Handler validates handle format 141 + - Creates LoginPageData with Error on failure 142 + - Template displays error in Pico CSS styled article 143 + ``` 144 + 145 + --- 146 + 147 + ## Template Data Contracts 148 + 149 + ### Input Contract (Handler → Template) 150 + 151 + The handler must provide: 152 + 153 + ```go 154 + data := LoginPageData{ 155 + Title: "Login - Bluesky Archive", // Required, non-empty 156 + Error: "", // Optional, empty string if no error 157 + Message: "", // Optional, rarely used 158 + Handle: "", // Optional, for repopulating form 159 + } 160 + ``` 161 + 162 + ### Output Contract (Template → User) 163 + 164 + The template must render: 165 + 166 + 1. Page title in `<title>` tag and page header 167 + 2. Error message in `<article aria-label="Error">` if present 168 + 3. Login form with: 169 + - Label and input for Bluesky handle 170 + - Submit button 171 + - HTML5 validation (required attribute) 172 + 4. Helpful context text explaining the login process 173 + 5. Minimal navigation with About/Help links 174 + 175 + --- 176 + 177 + ## Edge Cases 178 + 179 + ### 1. Extremely Long Error Messages 180 + 181 + **Scenario**: Server returns very long error message (e.g., full OAuth error JSON) 182 + 183 + **Handling**: Template should wrap error text properly using Pico CSS article styling. Long messages will word-wrap within the container. 184 + 185 + **Data Validation**: Handler should sanitize error messages to be user-friendly, not expose internal details. 186 + 187 + ### 2. Special Characters in Handle 188 + 189 + **Scenario**: User enters handle with special characters (e.g., `<script>alert('xss')</script>`) 190 + 191 + **Handling**: Go's `html/template` automatically escapes all template variables. No XSS vulnerability. 192 + 193 + **Data Validation**: Handle validation should reject invalid characters before they reach the template. 194 + 195 + ### 3. Missing Template File 196 + 197 + **Scenario**: Template file deleted or corrupted 198 + 199 + **Handling**: Go template execution will return error. Handler should catch and display generic error page (existing error handling). 200 + 201 + **No Data Impact**: This is a runtime error, not a data error. No data corruption possible. 202 + 203 + ### 4. Concurrent Requests 204 + 205 + **Scenario**: User opens multiple login pages simultaneously 206 + 207 + **Handling**: Each request gets independent LoginPageData instance. No shared state. No concurrency issues. 208 + 209 + **Stateless Design**: Template rendering is stateless - perfect for concurrent requests. 210 + 211 + --- 212 + 213 + ## Data Privacy Considerations 214 + 215 + ### Sensitive Data Handling 216 + 217 + **Handle (Bluesky username)**: 218 + - **Sensitivity**: Low (public identifier) 219 + - **Storage**: Not stored in this feature (passed to OAuth flow) 220 + - **Logging**: Should not be logged in error messages 221 + - **Display**: Safe to repopulate in form after validation error 222 + 223 + **Error Messages**: 224 + - **Sensitivity**: Low to Medium (may contain system information) 225 + - **Sanitization**: Must be user-friendly, not expose internal errors 226 + - **Example Good Error**: "Failed to connect to Bluesky. Please try again." 227 + - **Example Bad Error**: "panic: nil pointer dereference at oauth.go:123" 228 + 229 + **OAuth Tokens**: 230 + - **Sensitivity**: High (authentication credentials) 231 + - **Template Exposure**: NEVER passed to login template 232 + - **Existing Security**: Handled by bskyoauth library (unchanged) 233 + 234 + --- 235 + 236 + ## Comparison with Existing Pages 237 + 238 + This data structure follows the exact pattern used by other pages: 239 + 240 + **export.html**: 241 + ```go 242 + type ExportPageData struct { 243 + Title string 244 + Error string 245 + Message string 246 + CSRFToken string 247 + Status *ExportStatus 248 + Exports []ExportRecord 249 + } 250 + ``` 251 + 252 + **dashboard.html**: 253 + ```go 254 + type DashboardData struct { 255 + Title string 256 + Error string 257 + Message string 258 + Stats *ArchiveStats 259 + } 260 + ``` 261 + 262 + **login.html** (new): 263 + ```go 264 + type LoginPageData struct { 265 + Title string // Same pattern 266 + Error string // Same pattern 267 + Message string // Same pattern 268 + Handle string // Feature-specific 269 + } 270 + ``` 271 + 272 + **Consistency**: All pages use `Title`, `Error`, `Message` fields. This maintains template rendering consistency across the application. 273 + 274 + --- 275 + 276 + ## Summary 277 + 278 + This feature has minimal data modeling requirements: 279 + 280 + ✅ **New Data Structure**: LoginPageData (simple, 4 fields) 281 + ✅ **No Database Changes**: Zero schema modifications 282 + ✅ **No New Entities**: Purely presentation data 283 + ✅ **Consistent Pattern**: Follows existing template data conventions 284 + ✅ **Privacy Compliant**: No sensitive data exposure 285 + 286 + The data model is intentionally minimal because this is a UI refactoring, not a feature that introduces new business logic or data storage requirements.

··· 1 + # Implementation Plan: Login Form Template & Styling 2 + 3 + **Branch**: `006-login-template-styling` | **Date**: 2025-11-02 | **Spec**: [spec.md](spec.md) 4 + **Input**: Feature specification from `/specs/006-login-template-styling/spec.md` 5 + 6 + **Note**: This template is filled in by the `/speckit.plan` command. See `.specify/templates/commands/plan.md` for the execution workflow. 7 + 8 + ## Summary 9 + 10 + Migrate the login form from inline HTML in `internal/auth/oauth.go` to a proper template file at `internal/web/templates/pages/login.html`. Apply Pico CSS styling to match the rest of the application's design using the existing base template, navigation, and styling patterns. This is a straightforward UI refactoring that maintains 100% functional parity with the existing OAuth authentication flow while improving visual consistency and code maintainability. 11 + 12 + ## Technical Context 13 + 14 + **Language/Version**: Go 1.21+ (existing project standard) 15 + **Primary Dependencies**: Go standard library (html/template, net/http), Pico CSS (existing), bskyoauth (existing OAuth library) 16 + **Storage**: N/A (no data storage changes, UI-only refactoring) 17 + **Testing**: Go testing package (go test), manual UI testing for visual consistency 18 + **Target Platform**: Web application running on user's local machine (existing deployment model) 19 + **Project Type**: Single web application 20 + **Performance Goals**: Page load <500ms (from success criteria), template rendering <50ms 21 + **Constraints**: Must maintain 100% functional parity with existing OAuth flow, zero breaking changes to authentication 22 + **Scale/Scope**: Single login page template, ~1-2 files modified (oauth.go, new login.html), minimal scope UI-only change 23 + 24 + ## Constitution Check 25 + 26 + *GATE: Must pass before Phase 0 research. Re-check after Phase 1 design.* 27 + 28 + ### ✅ I. Data Privacy & Local-First Architecture 29 + **Status**: PASS - No impact 30 + 31 + This feature is a UI-only refactoring that does not affect data storage, privacy, or local-first architecture. All OAuth tokens and session management remain unchanged. 32 + 33 + ### ✅ II. Comprehensive & Accurate Archival 34 + **Status**: PASS - No impact 35 + 36 + No changes to archival functionality.

You'll need to load and parse templates. Check how other handlers do this - likely there's a template helper in `internal/web/handlers/template.go`. 233 + 234 + **Investigation needed**: 235 + ```bash 236 + # Check template helper structure 237 + cat internal/web/handlers/template.go | grep -A 10 "func.*Template" 238 + ``` 239 + 240 + **Assuming template helper exists** (adjust based on actual implementation): 241 + 242 + ```go 243 + import ( 244 + "net/http" 245 + "fmt" 246 + 247 + "github.com/shindakun/bskyarchive/internal/models" 248 + "github.com/shindakun/bskyarchive/internal/web/handlers" // For template rendering 249 + ) 250 + 251 + func (om *OAuthManager) HandleOAuthLogin(w http.ResponseWriter, r *http.Request) { 252 + if r.Method == http.MethodGet { 253 + // Render login template with empty data 254 + data := models.LoginPageData{ 255 + Title: "Login - Bluesky Archive", 256 + Error: "", 257 + Handle: "", 258 + } 259 + 260 + // Use existing template rendering helper 261 + // NOTE: Adjust this based on actual template helper implementation 262 + if err := handlers.RenderTemplate(w, "login.html", data); err != nil { 263 + http.Error(w, "Failed to render login page", http.StatusInternalServerError) 264 + log.Printf("Template rendering error: %v", err) 265 + return 266 + } 267 + return 268 + } 269 + 270 + // POST: Start OAuth flow with handle 271 + handle := r.FormValue("handle") 272 + if handle == "" { 273 + // Validation error - re-render with error message 274 + data := models.LoginPageData{ 275 + Title: "Login - Bluesky Archive", 276 + Error: "Bluesky handle is required", 277 + Handle: handle, // Empty in this case, but included for consistency 278 + } 279 + if err := handlers.RenderTemplate(w, "login.html", data); err != nil { 280 + http.Error(w, "Failed to render login page", http.StatusInternalServerError) 281 + return 282 + } 283 + return 284 + } 285 + 286 + // Start OAuth flow 287 + ctx := r.Context() 288 + flowState, err := om.client.StartAuthFlow(ctx, handle) 289 + if err != nil { 290 + // OAuth error - re-render with error message 291 + data := models.LoginPageData{ 292 + Title: "Login - Bluesky Archive", 293 + Error: "Failed to connect to Bluesky.

The `handlers.RenderTemplate` function name is a guess - adjust based on reality. 311 + 2. **Error Handling**: Always handle template rendering errors gracefully 312 + 3. **Logging**: Log template errors for debugging (use existing logger) 313 + 4. **Context**: Existing OAuth logic remains 100% unchanged 314 + 315 + **Verification**: 316 + ```bash 317 + # Compile check 318 + go build ./internal/auth/ 319 + 320 + # Run tests 321 + go test ./internal/auth/ 322 + ``` 323 + 324 + --- 325 + 326 + ### Step 4: Investigate and Integrate Template Rendering 327 + 328 + **Action**: Find the existing template rendering infrastructure 329 + 330 + **Commands**: 331 + ```bash 332 + # Find template initialization 333 + grep -r "template.New\|template.ParseFiles\|template.ParseGlob" internal/ 334 + 335 + # Find template execution 336 + grep -r "ExecuteTemplate\|Execute" internal/web/handlers/ 337 + 338 + # Check how other pages render templates 339 + cat internal/web/handlers/export.go | grep -A 5 "ExecuteTemplate" 340 + ``` 341 + 342 + **Common Patterns**: 343 + 344 + **Pattern 1**: Global template variable 345 + ```go 346 + // In main.go or server initialization 347 + var templates *template.Template 348 + 349 + func init() { 350 + templates = template.Must(template.ParseGlob("internal/web/templates/**/*.html")) 351 + } 352 + 353 + // In handler 354 + templates.ExecuteTemplate(w, "login.html", data) 355 + ``` 356 + 357 + **Pattern 2**: Template helper function 358 + ```go 359 + // In internal/web/handlers/template.go 360 + func RenderTemplate(w http.ResponseWriter, name string, data interface{}) error { 361 + return templates.ExecuteTemplate(w, name, data) 362 + } 363 + ``` 364 + 365 + **Pattern 3**: Per-request template parsing (less common, slower) 366 + ```go 367 + tmpl, err := template.ParseFiles("internal/web/templates/pages/login.html") 368 + if err != nil { 369 + return err 370 + } 371 + return tmpl.Execute(w, data) 372 + ``` 373 + 374 + **Action**: Once you identify the pattern, integrate it into the OAuth handler as shown in Step 3. 375 + 376 + **Verification**: 377 + ```bash 378 + # Start the development server 379 + go run cmd/bskyarchive/main.go 380 + 381 + # Test in browser 382 + open http://localhost:8080/auth/login 383 + 384 + # Check for template parsing errors in server logs 385 + ``` 386 + 387 + --- 388 + 389 + ### Step 5: Manual Testing 390 + 391 + **Action**: Comprehensive manual testing checklist 392 + 393 + #### Visual Testing 394 + 395 + 1. **Load login page**: 396 + ``` 397 + http://localhost:8080/auth/login 398 + ``` 399 + 400 + ✅ **Verify**: 401 + - [ ] Page loads without errors 402 + - [ ] Pico CSS styling applied (centered layout, styled form) 403 + - [ ] Navigation shows "Bluesky Archive" and "About" link 404 + - [ ] Page title shows "Login - Bluesky Archive" 405 + - [ ] Form has handle input with placeholder 406 + - [ ] Button says "Continue with Bluesky" 407 + - [ ] "About This Application" context section visible 408 + 409 + 2. **Responsive design testing**: 410 + - [ ] Desktop (1920px): Layout centered, readable 411 + - [ ] Tablet (768px): Layout adapts, no horizontal scroll 412 + - [ ] Mobile (375px): Form stacks vertically, touch-friendly 413 + 414 + 3. **Compare with other pages**: 415 + - Open http://localhost:8080/export 416 + - Compare: 417 + - [ ] Same header style 418 + - [ ] Same navigation structure 419 + - [ ] Same button styling 420 + - [ ] Same color scheme 421 + - [ ] Same typography (fonts, sizes) 422 + 423 + #### Functional Testing 424 + 425 + 4. **Empty form submission** (HTML5 validation): 426 + - Leave handle field empty 427 + - Click "Continue with Bluesky" 428 + - ✅ **Expected**: Browser shows "Please fill out this field" message 429 + - ✅ **Expected**: Form does NOT submit 430 + 431 + 5. **Valid handle submission** (OAuth flow): 432 + - Enter: `user.bsky.social` 433 + - Click "Continue with Bluesky" 434 + - ✅ **Expected**: Redirect to `https://bsky.social/oauth/authorize?...` 435 + - ✅ **Expected**: OAuth flow initiates (Bluesky login page) 436 + 437 + 6. **Server-side validation** (backend error): 438 + - Temporarily modify handler to always return error: 439 + ```go 440 + data.Error = "Test error message" 441 + ``` 442 + - Submit form 443 + - ✅ **Expected**: Error article displays in red 444 + - ✅ **Expected**: Error message: "Test error message" 445 + - ✅ **Expected**: Handle field repopulated with entered value 446 + - ✅ **Expected**: Page does NOT redirect 447 + 448 + 7. **OAuth initiation error** (network failure): 449 + - Disconnect network OR modify OAuth client to fail 450 + - Submit valid handle 451 + - ✅ **Expected**: Error article displays 452 + - ✅ **Expected**: User-friendly error message (not stack trace) 453 + - ✅ **Expected**: Handle field repopulated 454 + 455 + #### Security Testing 456 + 457 + 8. **XSS attempt**: 458 + -

Verify file path: `internal/web/templates/pages/login.html` 675 + 2. Check template glob pattern in template initialization 676 + 3. Ensure template parsing happens before handler registration 677 + 4. Check file permissions (readable) 678 + 679 + --- 680 + 681 + ### Problem: Template parses but displays blank page 682 + 683 + **Symptom**: HTTP 200 response, but empty body 684 + 685 + **Solution**: 686 + 1. Check template block names match base layout expectations 687 + 2. Verify `{{define "title"}}`, `{{define "nav"}}`, `{{define "content"}}` are all present 688 + 3. Check template execution error (may be silently failing) 689 + 4. Add logging: `log.Printf("Template exec error: %v", err)` 690 + 691 + --- 692 + 693 + ### Problem: Styling doesn't match other pages 694 + 695 + **Symptom**: Login page looks different from export page 696 + 697 + **Solution**: 698 + 1. Verify Pico CSS is loaded (check base.html) 699 + 2. Check class names: `container`, `article`, `<nav>` structure 700 + 3. Compare HTML structure with export.html side-by-side 701 + 4. Check for CSS syntax errors in template 702 + 5. Clear browser cache (Ctrl+Shift+R) 703 + 704 + --- 705 + 706 + ### Problem: OAuth flow broken after changes 707 + 708 + **Symptom**: Form submits but OAuth doesn't initiate 709 + 710 + **Solution**: 711 + 1. Check form `method="POST"` attribute 712 + 2. Verify form `action="/auth/login"` points to correct endpoint 713 + 3. Check `name="handle"` attribute on input field 714 + 4. Verify handler reads `r.FormValue("handle")` correctly 715 + 5. Add debug logging: `log.Printf("Handle: %s", handle)` 716 + 6. Check OAuth client initialization (should be unchanged) 717 + 718 + --- 719 + 720 + ### Problem: Error messages not displaying 721 + 722 + **Symptom**: Validation fails but no error shown 723 + 724 + **Solution**: 725 + 1. Verify `{{if .Error}}` block in template 726 + 2. Check handler sets `data.Error` field 727 + 3. Verify template data passed correctly: `log.Printf("Data: %+v", data)` 728 + 4. Check template execution succeeds (no early return on error) 729 + 5. Inspect HTML source: error may be rendered but CSS issue hiding it 730 + 731 + --- 732 + 733 + ### Problem: Form doesn't repopulate handle after error 734 + 735 + **Symptom**: User enters handle, gets error, handle disappears 736 + 737 + **Solution**: 738 + 1. Check template has `value="{{.Handle}}"` attribute 739 + 2. Verify handler sets `data.Handle = r.FormValue("handle")` on error 740 + 3. Test with debug output: `log.Printf("Repopulating handle: %s", data.Handle)` 741 + 742 + --- 743 + 744 + ## Success Criteria Verification 745 + 746 + Before marking this feature complete, verify all success criteria from [spec.md](spec.md): 747 + 748 + - [ ] **SC-001**: Login page loads in < 500ms 749 + - [ ] **SC-002**: 100% functional parity with existing OAuth flow 750 + - [ ] **SC-003**: 95%+ visual consistency with other pages 751 + - [ ] **SC-004**: Responsive design (320px - 1920px) 752 + - [ ] **SC-005**: Code maintainability improved (HTML separated from Go) 753 + 754 + --- 755 + 756 + ## Next Steps 757 + 758 + After completing implementation: 759 + 760 + 1. **Run `/speckit.tasks`**: Generate detailed task breakdown from this plan 761 + 2. **Create PR**: Submit for code review 762 + 3. **User Acceptance Testing**: Have team members test the login flow 763 + 4. **Document learnings**: Note any gotchas for future template migrations 764 + 5. **Consider follow-up**: Other pages that need template migration? 765 + 766 + --- 767 + 768 + ## Estimated Timeline 769 + 770 + - **Step 1** (Create template): 30 minutes 771 + - **Step 2** (Define struct): 5 minutes 772 + - **Step 3** (Update handler): 20 minutes 773 + - **Step 4** (Integrate template rendering): 10 minutes 774 + - **Step 5** (Manual testing): 30 minutes 775 + - **Step 6** (Integration tests): 30 minutes (optional) 776 + - **Step 7** (Code review): 15 minutes 777 + - **Step 8** (Commit/document): 10 minutes 778 + 779 + **Total**: ~2 hours (or ~1.5 hours if skipping automated tests) 780 + 781 + **Complexity**: 🟢 Low - Straightforward template migration with clear reference implementation 782 + 783 + --- 784 + 785 + ## Questions? 786 + 787 + If you encounter issues not covered in this guide: 788 + 789 + 1.

··· 1 + # Research: Login Form Template & Styling 2 + 3 + **Feature**: 006-login-template-styling 4 + **Date**: 2025-11-02 5 + **Status**: Complete 6 + 7 + ## Overview 8 + 9 + This feature requires minimal research as it leverages existing technologies and patterns already established in the codebase. The research focuses on understanding the current implementation and identifying the template patterns to follow. 10 + 11 + ## Research Areas 12 + 13 + ### 1. Current Login Form Implementation 14 + 15 + **Decision**: Login form is currently inline HTML in `internal/auth/oauth.go` (lines 40-52) 16 + 17 + **Current Implementation**: 18 + ```go 19 + w.Write([]byte(` 20 + <!DOCTYPE html> 21 + <html> 22 + <head><title>Login</title></head> 23 + <body> 24 + <h1>Login with Bluesky</h1> 25 + <form method="POST"> 26 + <label>Handle: <input type="text" name="handle" placeholder="user.bsky.social" required></label> 27 + <button type="submit">Login</button> 28 + </form> 29 + </body> 30 + </html> 31 + `)) 32 + ``` 33 + 34 + **Findings**: 35 + - Simple form with single input field (Bluesky handle) 36 + - POST method to same endpoint 37 + - No styling, no base template usage 38 + - No error handling UI 39 + - Comment indicates this is a placeholder: "This will be replaced with a proper template in later tasks" 40 + 41 + **Rationale**: This confirms the feature need - the inline HTML is a known technical debt item. 42 + 43 + --- 44 + 45 + ### 2. Existing Template Structure and Patterns 46 + 47 + **Decision**: Use Go's `html/template` package with existing base template pattern 48 + 49 + **Investigation**: 50 + - Examined `internal/web/templates/pages/export.html` as reference 51 + - Examined `internal/web/templates/pages/dashboard.html` for navigation 52 + - Examined `internal/web/templates/layouts/base.html` for base structure 53 + 54 + **Template Pattern Found**: 55 + ```html 56 + {{define "title"}}Page Title{{end}} 57 + 58 + {{define "nav"}} 59 + <nav class="container"> 60 + <ul> 61 + <li><strong>Bluesky Archive</strong></li> 62 + </ul> 63 + <ul> 64 + <!-- Navigation links --> 65 + </ul> 66 + </nav> 67 + {{end}} 68 + 69 + {{define "content"}} 70 + <!-- Page-specific content --> 71 + {{end}} 72 + ``` 73 + 74 + **Findings**: 75 + - Three main template blocks: `title`, `nav`, `content` 76 + - Base template provides overall HTML structure 77 + - Pico CSS classes used throughout (`container`, `hgroup`, `article`, etc.) 78 + - Form elements use Pico CSS default styling (minimal classes needed) 79 + - Error/message display uses `<article aria-label="Error/Success">` pattern 80 + - Navigation structure consistent across pages 81 + 82 + **Rationale**: Following this pattern ensures visual consistency and maintainability. 83 + 84 + --- 85 + 86 + ### 3. Pico CSS Form Styling Best Practices 87 + 88 + **Decision**: Use Pico CSS default form styling with minimal custom classes 89 + 90 + **Research**: Reviewed Pico CSS documentation and existing forms in codebase 91 + 92 + **Key Pico CSS Patterns**: 93 + - Forms automatically styled without classes 94 + - Input fields: `<input type="text" name="..." required>` (classless styling) 95 + - Buttons: `<button type="submit">` (primary button styling by default) 96 + - Labels: `<label>Text <input...></label>` (inline) or separate with `for` attribute 97 + - Fieldsets: `<fieldset><legend>Title</legend>...</fieldset>` for grouping 98 + - Error messages: Use `<small>` or `<article aria-label="Error">` for validation feedback 99 + - Container class: `class="container"` for responsive centering 100 + 101 + **Existing Form Examples in Codebase**: 102 + - export.html: Shows radio buttons, checkboxes, date inputs, fieldsets 103 + - All follow classless Pico CSS approach 104 + 105 + **Rationale**: Minimal markup required, Pico CSS handles visual styling automatically. This keeps templates clean and maintainable. 106 + 107 + --- 108 + 109 + ### 4. Template Rendering in Go Handlers 110 + 111 + **Decision**: Use existing template infrastructure, likely in `internal/web/handlers/template.go` 112 + 113 + **Investigation**: 114 + - Checked `internal/web/handlers/` directory structure 115 + - Found `template.go` - likely contains template rendering helpers 116 + - OAuth handler in `internal/auth/oauth.go` will need access to template rendering 117 + 118 + **Rendering Approach Options**: 119 + 120 + **Option A**: Create template rendering helper in auth package 121 + - Pros: Self-contained, no dependency on web/handlers 122 + - Cons: Duplicates template infrastructure 123 + 124 + **Option B**: Use existing template helper from web/handlers 125 + - Pros: Reuses existing infrastructure, maintains consistency 126 + - Cons: Adds dependency between auth and web packages 127 + 128 + **Option C**: Move template data preparation to web/handlers, keep auth logic pure 129 + - Pros: Better separation of concerns 130 + - Cons: May require restructuring handler registration 131 + 132 + **Decision**: Option B (use existing template helper) 133 + - This is the pattern used throughout the codebase 134 + - Auth handler can import and use the template rendering utility 135 + - Maintains consistency with other pages 136 + 137 + **Rationale**: Consistency with existing codebase patterns. Quick to implement, low risk. 138 + 139 + --- 140 + 141 + ### 5. Error Handling and User Feedback 142 + 143 + **Decision**: Use existing error display pattern with template data 144 + 145 + **Patterns Found**: 146 + - Template receives `.Error` and `.Message` fields 147 + - Error display: `{{if .Error}}<article aria-label="Error">{{.Error}}</article>{{end}}` 148 + - Success display: `{{if .Message}}<article>{{.Message}}</article>{{end}}` 149 + 150 + **Error Scenarios to Handle**: 151 + 1. Empty handle (HTML5 `required` attribute + backend validation) 152 + 2. Invalid handle format (backend validation) 153 + 3. OAuth flow initiation failure (backend error) 154 + 4. Network/connectivity issues (backend error) 155 + 156 + **Approach**: 157 + - Use HTML5 validation for client-side (required field) 158 + - Backend validation returns error via template data 159 + - Display error in consistent Pico CSS styled article 160 + 161 + **Rationale**: Follows existing UX patterns, provides clear user feedback. 162 + 163 + --- 164 + 165 + ### 6. Navigation Structure for Login Page 166 + 167 + **Decision**: Show simplified navigation (or no navigation) on login page 168 + 169 + **Consideration**: Login page is accessed by unauthenticated users 170 + 171 + **Options**: 172 + 173 + **Option A**: No navigation (user not logged in, can't access other pages) 174 + - Cleanest UX for login flow 175 + - Matches common login page patterns 176 + 177 + **Option B**: Show minimal navigation (About, Privacy links) 178 + - Provides context and information access 179 + - Slightly better UX for new users 180 + 181 + **Option C**: Show full navigation (same as other pages) 182 + - Most consistent with application design 183 + - Links would redirect to login anyway if not authenticated 184 + 185 + **Decision**: Option B (minimal navigation with About/Help links) 186 + - Balances consistency with practical UX 187 + - Can be adjusted during implementation based on feedback 188 + 189 + **Rationale**: Login page should be welcoming but focused. Minimal navigation provides context without distraction. 190 + 191 + --- 192 + 193 + ### 7. CSRF Protection Requirements 194 + 195 + **Decision**: Verify if CSRF protection is needed for public login page 196 + 197 + **Investigation**: 198 + - Checked `internal/web/middleware/csrf.go` 199 + - OAuth flow uses state parameter for CSRF protection (standard OAuth security) 200 + - Form submission starts OAuth flow, not a sensitive state change 201 + 202 + **Analysis**: 203 + - Login form POST starts OAuth flow (redirects to external Bluesky auth) 204 + - OAuth state parameter provides CSRF protection for the callback 205 + - No sensitive data modified by the login form POST itself 206 + - Standard practice: CSRF often not required for login pages that don't change state 207 + 208 + **Decision**: CSRF protection NOT required for login form 209 + - OAuth's state parameter handles CSRF for the callback 210 + - Login POST just initiates external redirect 211 + - Keeps implementation simple 212 + 213 + **Rationale**: OAuth protocol handles security. Adding CSRF would be redundant and complicate the flow. 214 + 215 + --- 216 + 217 + ## Summary of Technical Decisions 218 + 219 + | Area | Decision | Rationale | 220 + |------|----------|-----------| 221 + | Template Engine | Go html/template (existing) | Already in use, standard library | 222 + | Template Structure | Three-block pattern (title, nav, content) | Matches existing pages | 223 + | CSS Framework | Pico CSS (existing) | Classless, automatic form styling | 224 + | Template Rendering | Use existing web/handlers helper | Consistent with codebase | 225 + | Error Handling | Template data with .Error field | Existing pattern | 226 + | Navigation | Minimal (About/Help links) | Balanced UX for unauthenticated users | 227 + | CSRF Protection | Not required (OAuth state handles it) | Standard OAuth security | 228 + | Form Validation | HTML5 required + backend validation | Progressive enhancement | 229 + 230 + --- 231 + 232 + ## Implementation Approach 233 + 234 + Based on research findings: 235 + 236 + 1. **Create template file**: `internal/web/templates/pages/login.html` 237 + - Use three-block structure (title, nav, content) 238 + - Apply Pico CSS classless styling 239 + - Include error display pattern 240 + - Add helpful context text 241 + 242 + 2. **Modify OAuth handler**: `internal/auth/oauth.go` 243 + - Remove inline HTML string 244 + - Import template rendering helper 245 + - Pass error messages via template data 246 + - Maintain identical OAuth flow logic 247 + 248 + 3. **Test template rendering**: 249 + - Verify visual consistency with other pages 250 + - Test error display 251 + - Verify OAuth flow still works 252 + - Check responsive design 253 + 254 + --- 255 + 256 + ## Alternatives Considered 257 + 258 + ### Alternative 1: Use a different template engine (e.g., templ, gomponents) 259 + **Rejected**: Would require adding new dependencies. Current html/template is sufficient and already integrated. 260 + 261 + ### Alternative 2: Keep inline HTML, just add Pico CSS to it 262 + **Rejected**: Doesn't achieve the goal of separating concerns. Inline HTML remains unmaintainable. 263 + 264 + ### Alternative 3: Use JavaScript framework for login page 265 + **Rejected**: Massive overkill for a simple form. Goes against project philosophy of keeping things simple. 266 + 267 + --- 268 + 269 + ## Open Questions Resolved 270 + 271 + All questions from Technical Context have been resolved: 272 + 273 + - ✅ Template structure: Use existing three-block pattern 274 + - ✅ Pico CSS styling: Use classless default styling 275 + - ✅ Error handling: Use existing .Error template data pattern 276 + - ✅ Navigation: Minimal navigation for unauthenticated users 277 + - ✅ CSRF: Not required (OAuth state parameter handles security) 278 + - ✅ Template rendering: Use existing web/handlers helper 279 + 280 + --- 281 + 282 + ## Next Steps 283 + 284 + Proceed to Phase 1: Design & Contracts 285 + - Generate data-model.md (minimal - just template data structure) 286 + - Generate contracts/ (optional - this is internal UI, no external API) 287 + - Generate quickstart.md (step-by-step implementation guide)

··· 1 + # Feature Specification: Login Form Template & Styling 2 + 3 + **Feature Branch**: `006-login-template-styling` 4 + **Created**: 2025-11-02 5 + **Status**: Draft 6 + **Input**: User description: "Move the login form from inline HTML in internal/auth/oauth.go to a proper template file (internal/web/templates/pages/login.html) styled with Pico CSS to match the rest of the application's design. The form should use the same base template, navigation, and styling as other pages like export.html" 7 + 8 + ## User Scenarios & Testing *(mandatory)* 9 + 10 + ### User Story 1 - Login Form Displays with Consistent Styling (Priority: P1) 🎯 MVP 11 + 12 + Users visit the login page and see a professionally styled form that matches the rest of the application's design language, providing a cohesive user experience from first impression. 13 + 14 + **Why this priority**: First impression matters. The login page is the entry point for all users. Having it match the application's design establishes credibility and professionalism. This is the minimum viable change - a properly styled login form. 15 + 16 + **Independent Test**: Navigate to the login page, verify that the form uses Pico CSS styling, includes the application header/navigation structure, and visually matches the design of other pages like the export page. 17 + 18 + **Acceptance Scenarios**: 19 + 20 + 1. **Given** a user visits the login page, **When** the page loads, **Then** the login form displays with Pico CSS styling including proper form controls, buttons, and spacing 21 + 2. **Given** a user views the login page, **When** comparing it to other application pages (dashboard, export), **Then** the page uses the same base template, header, navigation structure, and color scheme 22 + 3. **Given** a user resizes their browser window, **When** viewing the login page, **Then** the form is responsive and maintains proper layout on mobile, tablet, and desktop screen sizes 23 + 24 + --- 25 + 26 + ### User Story 2 - Login Form Maintains Full Functionality (Priority: P1) 🎯 MVP 27 + 28 + The templated login form preserves all existing OAuth functionality, allowing users to successfully authenticate with their Bluesky handle. 29 + 30 + **Why this priority**: This is a non-negotiable requirement. The refactoring must not break existing authentication. Without working login, the application is unusable. 31 + 32 + **Independent Test**: Enter a valid Bluesky handle in the login form, submit it, verify that the OAuth flow initiates correctly and the user is redirected to Bluesky for authentication, then successfully returned to the application. 33 + 34 + **Acceptance Scenarios**: 35 + 36 + 1. **Given** a user enters a valid Bluesky handle, **When** they submit the login form, **Then** the OAuth flow initiates and redirects to Bluesky's authorization page 37 + 2. **Given** a user submits the form without entering a handle, **When** the form is validated, **Then** an error message displays indicating the handle is required 38 + 3. **Given** a user enters an invalid handle format, **When** they submit the form, **Then** appropriate error feedback is shown 39 + 4. **Given** a user completes the Bluesky OAuth flow, **When** they are redirected back to the application, **Then** they are successfully authenticated and see the dashboard 40 + 41 + --- 42 + 43 + ### User Story 3 - Login Page Shows Helpful Context (Priority: P2) 44 + 45 + Users see helpful information on the login page explaining what the application does and why they should sign in, improving the onboarding experience. 46 + 47 + **Why this priority**: While not strictly necessary for the template migration, adding contextual information improves user experience and reduces confusion for first-time users. This is a nice-to-have enhancement that leverages the template refactoring. 48 + 49 + **Independent Test**: Visit the login page as a new user, verify that descriptive text explains the application's purpose and what signing in will allow the user to do. 50 + 51 + **Acceptance Scenarios**: 52 + 53 + 1. **Given** a new user visits the login page, **When** they read the page content, **Then** they see a brief description of the application's purpose (archiving Bluesky posts) 54 + 2. **Given** a user views the login page, **When** looking at the form area, **Then** they see helpful text explaining what a Bluesky handle is (e.g., "Enter your Bluesky handle: user.bsky.social") 55 + 3. **Given** a user is on the login page, **When** they want to learn more before signing in, **Then** they see a link to an "About" page or privacy information 56 + 57 + --- 58 + 59 + ### Edge Cases 60 + 61 + - What happens when the template file is missing or corrupted? (Handler should return an error page rather than crash) 62 + - How does the system handle extremely long Bluesky handles? (Form should validate maximum length) 63 + - What happens if the OAuth client configuration is invalid? (Display user-friendly error message, not internal error details) 64 + - How does the login page render with JavaScript disabled? (Form should still be functional, graceful degradation) 65 + 66 + ## Requirements *(mandatory)* 67 + 68 + ### Functional Requirements 69 + 70 + - **FR-001**: System MUST render the login form using a template file located at `internal/web/templates/pages/login.html` 71 + - **FR-002**: Login page MUST use the same base template structure as other application pages (header, navigation, content area, footer) 72 + - **FR-003**: Login form MUST apply Pico CSS styling to all form elements (input fields, buttons, labels, validation messages) 73 + - **FR-004**: Login form MUST accept a Bluesky handle input with appropriate HTML5 validation attributes (required, type="text", placeholder text) 74 + - **FR-005**: Login form MUST submit via POST to the existing OAuth handler endpoint 75 + - **FR-006**: System MUST preserve all existing OAuth flow functionality (handle validation, authorization redirect, callback handling) 76 + - **FR-007**: Login page MUST display appropriate error messages when login fails (e.g., invalid handle, OAuth error, network error) 77 + - **FR-008**: Login page MUST be responsive and display correctly on mobile, tablet, and desktop screen sizes 78 + - **FR-009**: Login form MUST include CSRF protection using the existing CSRF token mechanism (if applicable to public login page) 79 + - **FR-010**: System MUST remove inline HTML from `internal/auth/oauth.go` and replace with template rendering 80 + 81 + ### Key Entities 82 + 83 + - **LoginPage**: Represents the login page view with properties including page title, form action URL, CSRF token, error messages, and contextual help text 84 + - **LoginForm**: Represents the form structure with handle input field, submit button, validation rules, and error display areas 85 + 86 + ## Success Criteria *(mandatory)* 87 + 88 + ### Measurable Outcomes 89 + 90 + - **SC-001**: Login page loads and displays with consistent styling in under 500ms on standard connections 91 + - **SC-002**: Login form maintains 100% functional parity with existing inline HTML implementation (all OAuth flows work identically) 92 + - **SC-003**: Visual consistency score of 95%+ when comparing login page design elements (colors, fonts, spacing, button styles) to other application pages 93 + - **SC-004**: Login form passes responsive design testing on screen sizes from 320px (mobile) to 1920px (desktop) wide without layout breaking 94 + - **SC-005**: Code maintainability improves: login form HTML is separated from Go code, enabling designers to modify templates without touching backend code 95 + 96 + ## Assumptions 97 + 98 + - Application already uses Pico CSS framework consistently across all pages 99 + - Base template system is established with navigation, header, and content blocks defined 100 + - Existing OAuth flow in `internal/auth/oauth.go` is working correctly and only the form rendering needs to be changed 101 + - CSRF protection middleware is already in place for form submissions (or not required for public login page) 102 + - Template rendering infrastructure (template parsing, execution, error handling) is already implemented 103 + - No changes to OAuth configuration or authentication logic are required 104 + - Current placeholder text "user.bsky.social" is sufficient for handle input guidance 105 + 106 + ## Out of Scope 107 + 108 + - Changes to OAuth authentication logic or flow sequence 109 + - Multi-factor authentication or additional security measures 110 + - Alternative authentication methods (email/password, SSO, etc.) 111 + - Password reset or account recovery flows (Bluesky OAuth handles this externally) 112 + - User registration functionality (handled by Bluesky) 113 + - Internationalization or multi-language support for login page 114 + - Advanced form features like autocomplete handle suggestions or handle validation before submission 115 + - Analytics or tracking on login page 116 + - Dark mode or theme switching (unless already implemented application-wide)

specs/006-login-template-styling/tasks.md
··· 1 + # Tasks: Login Form Template & Styling 2 + 3 + **Input**: Design documents from `/specs/006-login-template-styling/` 4 + **Prerequisites**: plan.md, spec.md, research.md, data-model.md, contracts/template-interface.md, quickstart.md 5 + 6 + **Tests**: Manual testing only - no automated test tasks unless explicitly requested. 7 + 8 + **Organization**: Tasks are grouped by user story to enable independent implementation and testing of each story. Both P1 stories (US1 & US2) are tightly coupled and must be implemented together as they share the same code changes. 9 + 10 + ## Format: `[ID] [P?] [Story] Description` 11 + 12 + - **[P]**: Can run in parallel (different files, no dependencies) 13 + - **[Story]**: Which user story this task belongs to (e.g., US1, US2, US3) 14 + - Include exact file paths in descriptions 15 + 16 + ## Path Conventions 17 + 18 + This is a single-project Go application with structure: 19 + - `internal/` - application code 20 + - `internal/web/templates/` - template files 21 + - `tests/` - test files (not used in this feature) 22 + 23 + --- 24 + 25 + ## Phase 1: Setup (Minimal - No Project Initialization Needed) 26 + 27 + **Purpose**: Verify prerequisites before starting implementation 28 + 29 + - [X] T001 Verify Pico CSS is loaded in internal/web/templates/layouts/base.html 30 + - [X] T002 Verify base template structure exists with title, nav, and content blocks in internal/web/templates/layouts/base.html 31 + - [X] T003 Review reference templates (internal/web/templates/pages/export.html and dashboard.html) to understand existing patterns 32 + - [X] T004 Verify template rendering infrastructure exists (check internal/web/handlers/template.go or similar) 33 + 34 + **Checkpoint**: Prerequisites verified - existing template infrastructure is ready for use. 35 + 36 + --- 37 + 38 + ## Phase 2: Foundation (Template Data Model) 39 + 40 + **Purpose**: Define the data structure that will be passed to the template. This is shared infrastructure needed by both P1 user stories. 41 + 42 + **⚠️ CRITICAL**: This phase must complete before user story implementation begins. 43 + 44 + - [X] T005 Create LoginPageData struct in internal/models/page_data.go with fields: Title, Error, Message, Handle 45 + - [X] T006 Add struct documentation comments explaining each field's purpose 46 + - [X] T007 Verify Go code compiles: `go build ./internal/models/` 47 + 48 + **Checkpoint**: Foundation ready - LoginPageData struct defined and compiles successfully. User story implementation can begin. 49 + 50 + --- 51 + 52 + ## Phase 3: User Stories 1 & 2 - Login Form Template & Functionality (Priority: P1) 🎯 MVP 53 + 54 + **Goal**: Create a professionally styled login form template that maintains 100% OAuth functional parity 55 + 56 + **Why Combined**: These two P1 stories share the same code files and must be implemented together: 57 + - US1 (Styling): Creates the template with Pico CSS 58 + - US2 (Functionality): Updates the handler to use the template and preserve OAuth flow 59 + 60 + Both stories modify the same handler file and create the same template, so they cannot be separated. 61 + 62 + **Independent Test**: 63 + 1. Navigate to /auth/login and verify visual styling matches export.html (US1) 64 + 2. Enter valid Bluesky handle, submit, verify OAuth flow initiates correctly (US2) 65 + 3. Test responsive design on mobile/tablet/desktop (US1) 66 + 4. Test error handling: empty handle, invalid format, OAuth errors (US2) 67 + 68 + **Acceptance Scenarios** (from spec.md): 69 + - US1: Pico CSS styling applied, responsive design, matches other pages 70 + - US2: OAuth flow works, validation works, errors display correctly 71 + 72 + ### Implementation Tasks (US1 & US2 Combined) 73 + 74 + - [X] T008 [US1+US2] Create login template file at internal/web/templates/pages/login.html with three-block structure (title, nav, content) 75 + -

Ready for PR submission. 160 + 161 + --- 162 + 163 + ## Dependencies & Execution Order 164 + 165 + ### Phase Dependencies 166 + 167 + - **Setup (Phase 1)**: No dependencies - can start immediately 168 + - **Foundation (Phase 2)**: Depends on Setup - BLOCKS user stories 169 + - **User Stories 1 & 2 (Phase 3)**: Depends on Foundation - Must be done together (same files) 170 + - **User Story 3 (Phase 4)**: Depends on Phase 3 (adds to existing template) 171 + - **Polish (Phase 5)**: Depends on all user stories 172 + 173 + ### User Story Dependencies 174 + 175 + - **User Story 1 (P1)**: Creates template - MVP functionality 176 + - **User Story 2 (P1)**: Uses template created by US1 - Must implement together 177 + - **User Story 3 (P2)**: Adds content to template from US1 - Can be done after MVP 178 + 179 + ### Critical Path 180 + 181 + ``` 182 + Setup → Foundation → US1+US2 (together) → US3 → Polish 183 + ``` 184 + 185 + **Cannot Parallelize**: US1 and US2 modify the same files (oauth.go creates template, both use same template file). Must be implemented as one unit. 186 + 187 + **Can Skip**: US3 (contextual help) is optional enhancement - can ship MVP without it. 188 + 189 + --- 190 + 191 + ## Parallel Opportunities 192 + 193 + **Limited Parallel Execution**: Due to shared files, most tasks must be sequential. 194 + 195 + ### Phase 2 (Foundation) - Sequential Only 196 + - T005, T006, T007 must run in order (create struct, document, verify) 197 + 198 + ### Phase 3 (US1+US2) - Some Parallelization Possible 199 + 200 + **Template Creation** (T008-T019) can be done as one block: 201 + - Create complete template file with all sections at once 202 + - OR break into subsections if multiple people working 203 + 204 + **Handler Modification** (T020-T027) must be sequential: 205 + - Requires understanding template rendering pattern first 206 + - Each change builds on previous 207 + 208 + **Manual Testing** (T029-T040) can be parallelized: 209 + - Multiple testers can verify different scenarios simultaneously 210 + - E.g., one person tests styling, another tests OAuth flow 211 + 212 + ### Phase 4 (US3) - Sequential 213 + - Tasks modify same template file, must be in order 214 + 215 + ### Phase 5 (Polish) - Some Parallelization 216 + 217 + Parallel testing possible: 218 + - T049-T052 (code review items) - different reviewers 219 + - T053-T059 (various tests) - different testers 220 + 221 + --- 222 + 223 + ## Implementation Strategy 224 + 225 + ### MVP First (Recommended) 226 + 227 + 1. Complete Phase 1: Setup (4 tasks) - Verify prerequisites 228 + 2. Complete Phase 2: Foundation (3 tasks) - Define data model 229 + 3. Complete Phase 3: US1+US2 (33 tasks) - Template + OAuth functionality 230 + 4. **STOP and VALIDATE**: Test login flow end-to-end 231 + 5. Deploy/demo if ready 232 + 233 + **Result**: Users have a professionally styled login form with working OAuth authentication. 234 + 235 + ### Incremental Delivery 236 + 237 + 1. Complete Setup + Foundation → Data model defined 238 + 2. Add US1+US2 → Test independently → **Deploy/Demo (MVP!)** - Professional login 239 + 3. Add US3 → Test independently → Deploy/Demo - Improved onboarding 240 + 4. Polish → Final verification → Deploy/Demo - Production ready 241 + 242 + ### Single Developer Strategy 243 + 244 + **Estimated Timeline**: 245 + - Phase 1 (Setup): 15 minutes 246 + - Phase 2 (Foundation): 10 minutes 247 + - Phase 3 (US1+US2): 60-90 minutes (template creation + handler + testing) 248 + - Phase 4 (US3): 15 minutes (add contextual text) 249 + - Phase 5 (Polish): 20 minutes (review + edge cases) 250 + 251 + **Total**: ~2 hours (matches quickstart.md estimate) 252 + 253 + **Workflow**: 254 + 1. Run through setup quickly (T001-T004) 255 + 2. Create data struct (T005-T007) 256 + 3. Focus time on template creation (T008-T019) - ~30 minutes 257 + 4. Update handler carefully (T020-T027) - ~30 minutes 258 + 5. Thorough manual testing (T029-T040) - ~30 minutes 259 + 6. Add contextual help if time permits (T041-T048) - ~15 minutes 260 + 7. Polish and commit (T049-T062) - ~20 minutes 261 + 262 + --- 263 + 264 + ## Notes 265 + 266 + - **No Automated Tests**: This feature uses manual testing only per quickstart.md guidance 267 + - **Shared Code**: US1 and US2 cannot be separated - they modify the same files for the same goal 268 + - **Low Risk**: This is a UI-only refactoring with clear reference implementations (export.html) 269 + - **Quick Win**: Simple feature with high visual impact, good for demonstrating progress 270 + - **Template Pattern**: Once established, this pattern can be reused for other template migrations 271 + 272 + --- 273 + 274 + ## Total Task Count: 62 tasks 275 + 276 + ### Breakdown by Phase: 277 + - Phase 1 (Setup): 4 tasks 278 + - Phase 2 (Foundation): 3 tasks 279 + - Phase 3 (US1+US2 - MVP): 33 tasks 280 + - Phase 4 (US3 - Enhancement): 8 tasks 281 + - Phase 5 (Polish): 14 tasks 282 + 283 + ### Breakdown by User Story: 284 + - Setup/Foundation: 7 tasks (shared infrastructure) 285 + - User Story 1+2 (P1): 33 tasks - MVP (combined due to shared files) 286 + - User Story 3 (P2): 8 tasks - Enhancement 287 + - Polish: 14 tasks (cross-cutting) 288 + 289 + ### Manual Testing: 18 test tasks (T029-T040, T046-T048, T053-T059) 290 + 291 + ### Parallel Opportunities: Very limited due to shared files 292 + - Template sections could be created by different people 293 + - Testing can be parallelized across multiple testers 294 + 295 + ### MVP Scope (recommended): 296 + - Phase 1: Setup (4 tasks) 297 + - Phase 2: Foundation (3 tasks) 298 + - Phase 3: User Story 1+2 (33 tasks) 299 + - **Total MVP: 40 tasks** (~1.5 hours) 300 + 301 + After MVP, User Story 3 can be added incrementally if desired (adds contextual help text).
