Edit & Delete Flush Feature#

Overview#

This feature allows users to edit and delete their own flush records directly from their profile page. The implementation includes a modal interface for editing, client-side validation, and proper handling through the AT Protocol and Jetstream firehose.

What Was Added#

1. API Client Functions (src/lib/api-client.ts)#

Added two new functions to handle record management:

• deleteFlushRecord(session, recordUri): Deletes a flush record using the AT Protocol's deleteRecord method
• updateFlushRecord(session, recordUri, text, emoji, originalCreatedAt): Updates a flush record using the AT Protocol's putRecord method

Both functions:

• Parse AT URIs correctly (format: at://did:plc:xxx/collection.name/rkey)
• Use the OAuth session's Agent for authenticated requests
• Include proper error handling and logging
• Preserve the original createdAt timestamp on updates

2. Edit Modal Component (src/components/EditFlushModal.tsx)#

A beautiful modal dialog that provides:

• Pre-populated form with the flush's current text and emoji
• Character counter (59 character limit)
• Emoji selector with all approved emojis
• Content validation (banned words, character limits)
• Delete confirmation workflow
• Loading states for all async operations
• Error handling with user-friendly messages
• Backdrop click to close
• Responsive design for mobile devices

3. Profile Page Updates (src/app/profile/[handle]/page.tsx)#

Enhanced the profile page with:

• Edit button on each flush (only visible to the flush owner)
• Authentication check using useAuth() hook to compare DIDs
• Integration with EditFlushModal component
• State management for editing operations
• Success/error message display
• Optimistic UI updates (updates local state immediately)

New state variables:

• editingFlush: Tracks which flush is being edited
• actionError: Displays error messages
• actionSuccess: Displays success messages

New functions:

• isOwnProfile(): Checks if the logged-in user owns the profile
• handleUpdateFlush(): Handles the update operation
• handleDeleteFlush(): Handles the delete operation

4. Profile Styles (src/app/profile/[handle]/profile.module.css)#

Added styles for:

• .contentRight: Container for timestamp and edit button
• .editButton: Pencil icon button with hover effects
• .actionError: Error message styling
• .actionSuccess: Success message styling

5. Edit Modal Styles (src/components/EditFlushModal.module.css)#

Complete styling for the modal including:

• Dark backdrop overlay
• Centered modal with max-width
• Form inputs and emoji grid
• Action buttons (Save, Cancel, Delete)
• Delete confirmation UI
• Responsive mobile layout
• Smooth transitions and hover effects

6. Jetstream Consumer (scripts/firehose-worker.js)#

Updated to properly handle:

• Delete operations: Removes records from Supabase when deleted from the network
• Update operations: Updates existing records with new content
• URI construction for record matching
• Proper error handling for database operations

How It Works#

User Flow#

1. User navigates to their own profile

   • Edit buttons appear next to each of their flushes
   • Buttons are hidden for other users' profiles

2. User clicks edit button

   • Modal opens with pre-filled form
   • Current text and emoji are displayed
   • User can modify text and/or emoji
   • Character counter shows remaining characters

3. User saves changes

   • Validation runs (banned words, character limits)
   • API call made to update the record via AT Protocol
   • Local state updates immediately (optimistic UI)
   • Success message displayed
   • Modal closes automatically

4. User deletes a flush

   • Clicks "Delete Flush" button
   • Confirmation prompt appears
   • On confirmation, record is deleted via AT Protocol
   • Record removed from local state
   • Success message displayed
   • Modal closes

Technical Flow#

Update Operation#

User clicks Save
  → Validation (client-side)
  → updateFlushRecord(session, uri, text, emoji, createdAt)
  → Agent.api.com.atproto.repo.putRecord()
  → PDS updates the record
  → Jetstream firehose emits 'update' event
  → Worker processes event
  → Supabase record updated
  → UI updates optimistically

Delete Operation#

User confirms delete
  → deleteFlushRecord(session, uri)
  → Agent.api.com.atproto.repo.deleteRecord()
  → PDS deletes the record
  → Jetstream firehose emits 'delete' event
  → Worker processes event
  → Supabase record deleted
  → UI updates optimistically

Authorization#

• Uses OAuth session from @atproto/oauth-client-browser
• Compares session.sub (user's DID) with profileData.did
• Edit buttons only visible when DIDs match
• AT Protocol handles authorization at the PDS level
• Users can only edit/delete their own records

Validation#

All validation from the original flush creation is preserved:

• Character limit: 59 characters
• Banned words: Content filtering via containsBannedWords()
• Text sanitization: via sanitizeText()
• Emoji validation: Only approved emojis from the list
• Authentication: Must be logged in

Error Handling#

Comprehensive error handling at every level:

• Network failures
• Authorization errors
• Validation errors
• User-friendly error messages
• Console logging for debugging
• Graceful degradation

Responsive Design#

The modal and edit buttons work beautifully on:

• Desktop screens
• Tablets
• Mobile devices

Features:

• Touch-friendly button sizes
• Readable text at all sizes
• Scrollable modal content
• Proper spacing and padding

Future Enhancements#

Potential improvements:

1. Edit history: Track when records were edited
2. Undo functionality: Allow users to revert changes
3. Bulk operations: Edit/delete multiple flushes at once
4. Keyboard shortcuts: Quick access to edit/delete
5. Inline editing: Edit directly in the feed without modal
6. Draft saving: Save edits as drafts before publishing

Testing Checklist#

To verify the feature works correctly:

• Edit button appears on own profile only
• Edit button hidden on other users' profiles
• Modal opens when edit button clicked
• Form pre-populates with current values
• Text changes are validated
• Emoji selection works
• Character counter updates correctly
• Save button updates the record
• Delete button shows confirmation
• Delete confirmation works
• Cancel buttons close modal
• Success messages display
• Error messages display
• Local state updates optimistically
• Jetstream updates Supabase correctly
• Mobile layout works properly

Notes#

• Records maintain their original createdAt timestamp when updated
• Updates create a new CID (Content Identifier) for the record
• The URI remains the same (same rkey)
• Deletes are permanent and cannot be undone
• All operations respect AT Protocol's distributed architecture
