# Volt Plugin System Spec
2
+
3
+
## Overview
4
+
5
+
The plugin system enables extending the framework with custom `data-x-*` attribute bindings.
6
+
7
+
Plugins follow the same binding patterns as core bindings (text, html, class, events) but can implement specialized behaviors like persistence, scrolling, and URL synchronization.
8
+
9
+
## Design Goals
10
+
11
+
### Extensibility
12
+
13
+
Plugins can access the full binding context including the DOM element, reactive scope, signal utilities, and cleanup registration.
14
+
15
+
### Explicit Opt-In
16
+
17
+
Built-in plugins require explicit registration to keep the core bundle minimal. Applications only load the functionality they use.
18
+
19
+
### Simplicity
20
+
21
+
Plugin API mirrors the internal binding handler signature. Developers who end up familiar with Volt internals can easily create plugins.
22
+
23
+
### Consistency
24
+
25
+
Plugins should integrate seamlessly with the mount/unmount lifecycle, cleanup system, and reactive primitives.
26
+
27
+
## Plugin API
28
+
29
+
### Registration
30
+
31
+
Plugins are registered using the `registerPlugin()` function:
32
+
33
+
```ts
34
+
registerPlugin(name: string, handler: PluginHandler): void
35
+
```
36
+
37
+
The plugin name becomes the `data-x-*` attribute suffix. For example, registering a plugin named `"tooltip"` enables `data-x-tooltip` attributes.
38
+
39
+
### Plugin Handler
40
+
41
+
Plugin handlers receive a context object and the attribute value:
42
+
43
+
```ts
44
+
type PluginHandler = (context: PluginContext, value: string) => void
45
+
```
46
+
47
+
The handler should:
48
+
49
+
1. Parse the attribute value
50
+
2. Set up bindings and subscriptions
51
+
3. Register cleanup functions for unmount
52
+
53
+
### PluginContext
54
+
55
+
The context object provides:
56
+
57
+
```ts
58
+
interface PluginContext {
59
+
element: Element; // The bound DOM element
60
+
scope: Scope; // Reactive scope with signals
61
+
addCleanup(fn: CleanupFunction): void; // Register cleanup
62
+
findSignal(path: string): Signal | undefined; // Locate signals by path
63
+
evaluate(expression: string): unknown; // Evaluate expressions
64
+
}
65
+
```
66
+
67
+
### Example: Custom Tooltip Plugin
68
+
69
+
```ts
70
+
import { registerPlugin } from 'volt';
71
+
72
+
registerPlugin('tooltip', (context, value) => {
73
+
const tooltip = document.createElement('div');
74
+
tooltip.className = 'tooltip';
75
+
tooltip.textContent = context.evaluate(value);
76
+
77
+
const show = () => document.body.appendChild(tooltip);
78
+
const hide = () => tooltip.remove();
79
+
80
+
context.element.addEventListener('mouseenter', show);
81
+
context.element.addEventListener('mouseleave', hide);
82
+
83
+
context.addCleanup(() => {
84
+
hide();
85
+
context.element.removeEventListener('mouseenter', show);
86
+
context.element.removeEventListener('mouseleave', hide);
87
+
});
88
+
89
+
const signal = context.findSignal(value);
90
+
if (signal) {
91
+
const unsubscribe = signal.subscribe((newValue) => {
92
+
tooltip.textContent = String(newValue);
93
+
});
94
+
context.addCleanup(unsubscribe);
95
+
}
96
+
});
97
+
```
98
+
99
+
## Built-in Plugins
100
+
101
+
Volt.js ships with three built-in plugins that must be explicitly registered.
102
+
103
+
### data-x-persist
104
+
105
+
Synchronizes signal values with persistent storage (`localStorage`, `sessionStorage`, `IndexedDB`).
106
+
107
+
**Syntax:**
108
+
109
+
```html
110
+
<input data-x-persist="signalName:storageType" />
111
+
```
112
+
113
+
**Storage Types:**
114
+
115
+
- `local` - localStorage (persistent across sessions)
116
+
- `session` - sessionStorage (cleared on tab close)
117
+
- `indexeddb` - IndexedDB (large datasets, async)
118
+
- Custom adapters via `registerStorageAdapter()`
119
+
120
+
**Behavior:**
121
+
122
+
1. On mount: Load persisted value into signal (if exists)
123
+
2. On signal change: Persist new value to storage
124
+
3. On unmount: Clean up storage listeners
125
+
126
+
**Examples:**
127
+
128
+
```html
129
+
<!-- Persist counter to localStorage -->
130
+
<div data-x-text="count" data-x-persist="count:local"></div>
131
+
132
+
<!-- Persist form state to sessionStorage -->
133
+
<input data-x-on-input="updateForm" data-x-persist="formData:session" />
134
+
135
+
<!-- Persist large dataset to IndexedDB -->
136
+
<div data-x-persist="userData:indexeddb"></div>
137
+
```
138
+
139
+
**Custom Storage Adapters:**
140
+
141
+
```ts
142
+
interface StorageAdapter {
143
+
get(key: string): Promise<unknown> | unknown;
144
+
set(key: string, value: unknown): Promise<void> | void;
145
+
remove(key: string): Promise<void> | void;
146
+
}
147
+
148
+
registerStorageAdapter('custom', {
149
+
async get(key) { /* ... */ },
150
+
async set(key, value) { /* ... */ },
151
+
async remove(key) { /* ... */ }
152
+
});
153
+
```
154
+
155
+
### data-x-scroll
156
+
157
+
Manages scroll behavior including position restoration, programmatic scrolling, scroll spy, and smooth scrolling.
158
+
159
+
**Syntax:**
160
+
161
+
```html
162
+
<!-- Scroll position restoration -->
163
+
<div data-x-scroll="restore:position"></div>
164
+
165
+
<!-- Scroll to element when signal changes -->
166
+
<div data-x-scroll="scrollTo:targetId"></div>
167
+
168
+
<!-- Scroll spy (updates signal when in viewport) -->
169
+
<div data-x-scroll="spy:isVisible"></div>
170
+
171
+
<!-- Smooth scroll behavior -->
172
+
<div data-x-scroll="smooth:true"></div>
173
+
```
174
+
175
+
**Behaviors:**
176
+
177
+
**Position Restoration:**
178
+
179
+
```html
180
+
<div id="content" data-x-scroll="restore:scrollPos">
181
+
<!-- scroll position saved on scroll, restored on mount -->
182
+
</div>
183
+
```
184
+
185
+
Saves scroll position to the specified signal and restores on mount.
186
+
187
+
**Scroll-To:**
188
+
189
+
```html
190
+
<button data-x-on-click="scrollToSection.set('section2')">Go to Section 2</button>
191
+
<div id="section2" data-x-scroll="scrollTo:scrollToSection"></div>
192
+
```
193
+
194
+
Scrolls to element when the specified signal changes to match element's ID or selector.
195
+
196
+
**Scroll Spy:**
197
+
198
+
```html
199
+
<nav>
200
+
<a data-x-class="{ active: section1Visible }">Section 1</a>
201
+
<a data-x-class="{ active: section2Visible }">Section 2</a>
202
+
</nav>
203
+
<div data-x-scroll="spy:section1Visible"></div>
204
+
<div data-x-scroll="spy:section2Visible"></div>
205
+
```
206
+
207
+
Updates signal with boolean visibility state using Intersection Observer.
208
+
209
+
**Smooth Scrolling:**
210
+
211
+
```html
212
+
<div data-x-scroll="smooth:behavior"></div>
213
+
```
214
+
215
+
Enables smooth scrolling with configurable behavior from signal.
216
+
217
+
### data-x-url
218
+
219
+
Synchronizes signal values with URL parameters and hash-based routing.
220
+
221
+
**Syntax:**
222
+
223
+
```html
224
+
<!-- One-way: Read URL param into signal on mount -->
225
+
<input data-x-url="read:searchQuery" />
226
+
227
+
<!-- Bidirectional: Keep URL and signal in sync -->
228
+
<input data-x-url="sync:filter" />
229
+
230
+
<!-- Hash-based routing -->
231
+
<div data-x-url="hash:currentRoute"></div>
232
+
```
233
+
234
+
**Behaviors:**
235
+
236
+
**Read URL Parameters:**
237
+
238
+
```html
239
+
<!-- Initialize signal from ?tab=profile -->
240
+
<div data-x-url="read:tab"></div>
241
+
```
242
+
243
+
Reads URL parameter on mount and sets signal value. Signal changes do not update URL.
244
+
245
+
**Bidirectional Sync:**
246
+
247
+
```html
248
+
<!-- Keep ?search=query in sync with searchQuery signal -->
249
+
<input data-x-on-input="handleSearch" data-x-url="sync:searchQuery" />
250
+
```
251
+
252
+
Changes to signal update URL parameter, changes to URL update signal. Uses History API for clean URLs.
253
+
254
+
**Hash Routing:**
255
+
256
+
```html
257
+
<!-- Sync with #/page/about -->
258
+
<div data-x-url="hash:route"></div>
259
+
<div data-x-text="route === '/page/about' ? 'About Page' : 'Home'"></div>
260
+
```
261
+
262
+
Keeps hash portion of URL in sync with signal. Useful for client-side routing.
263
+
264
+
**Notes:**
265
+
266
+
- Uses History API (`pushState`/`replaceState`) for param sync
267
+
- Listens to `popstate` for browser back/forward
268
+
- Debounces URL updates to avoid excessive history entries
269
+
- Automatically serializes/deserializes values (strings, numbers, booleans)
270
+
271
+
## Implementation
272
+
273
+
### Integration
274
+
275
+
The binder system checks the plugin registry before falling through to unknown attribute warnings
276
+
277
+
### Context
278
+
279
+
The binder creates a PluginContext from BindingContext:
280
+
281
+
```ts
282
+
function createPluginContext(bindingContext: BindingContext): PluginContext {
283
+
return {
284
+
element: bindingContext.element,
285
+
scope: bindingContext.scope,
286
+
addCleanup: (fn) => bindingContext.cleanups.push(fn),
287
+
findSignal: (path) => findSignalInScope(bindingContext.scope, path),
288
+
evaluate: (expr) => evaluate(expr, bindingContext.scope)
289
+
};
290
+
}
291
+
```
292
+
293
+
### Module Structure
294
+
295
+
```sh
296
+
src/
297
+
core/
298
+
plugin.ts # Plugin registry and API
299
+
binder.ts # Modified to integrate plugins
300
+
plugins/
301
+
persist.ts # Persistence plugin
302
+
scroll.ts # Scroll behavior plugin
303
+
url.ts # URL synchronization plugin
304
+
index.ts # Exports registerPlugin and built-in plugins
305
+
```
306
+
307
+
## Bundle Size Considerations
308
+
309
+
With explicit registration, applications control their bundle size:
310
+
311
+
- Core framework: ~15 KB gzipped (no plugins)
312
+
- Each plugin: ~1-3 KB gzipped
313
+
- Applications import only what they use
314
+
- Tree-shaking eliminates unused plugins
315
+
316
+
Example bundle breakdown:
317
+
318
+
```sh
319
+
volt/core : 15 KB
320
+
volt/plugins/persist : 2 KB
321
+
volt/plugins/scroll : 2.5 KB
322
+
volt/plugins/url : 1.5 KB
323
+
--------------------------------
324
+
Total (all plugins) : 21 KB
325
+
```
326
+
327
+
## Extension Points
328
+
329
+
Future plugin capabilities:
330
+
331
+
- Lifecycle hooks (beforeMount, afterMount, beforeUnmount)
332
+
- Plugin dependencies and composition
333
+
- Plugin configuration API
334
+
- Async plugin initialization
335
+
- Plugin registry
