When the user edits the value, it emits an + `a2ui:datamodel` event via the `emit` callback +4. **The event string format** is `a2ui:datamodel:{path}:{value}` + +### Using `emitBinding` + +Catalog components use the `emitBinding` utility to emit binding events: + +```typescript +import { emitBinding } from '@cacheplane/chat'; + +// In your component's change handler: +onInput(event: Event): void { + const val = (event.target as HTMLInputElement).value; + emitBinding(this.emit(), this._bindings(), 'value', val); +} +``` + +### Known Limitations + +The current binding mechanism is client-side only — the `a2ui:datamodel` events are emitted +but do not yet flow through the render lib's `StateStore`. This means data model updates +from user input are not reflected back to other components in real time. Full `StateStore` +integration is planned for a future release. + +For now, data model state is refreshed when the agent sends an `updateDataModel` message. +``` + +- [ ] **Step 2: Add component prop reference tables to catalog.mdx** + +Add prop reference tables to `apps/website/content/docs/render/a2ui/catalog.mdx` after the existing component sections: + +```mdx +## Component Reference + +### Input Components + +#### TextField + +| Prop | Type | Default | Description | +|------|------|---------|-------------| +| `label` | `string` | `''` | Label text above the input | +| `value` | `string` | `''` | Current input value | +| `placeholder` | `string` | `''` | Placeholder text | +| `validationResult` | `A2uiValidationResult` | `{ valid: true, errors: [] }` | Validation state | + +#### CheckBox + +| Prop | Type | Default | Description | +|------|------|---------|-------------| +| `label` | `string` | `''` | Label text next to checkbox | +| `checked` | `boolean` | `false` | Whether the checkbox is checked | +| `validationResult` | `A2uiValidationResult` | `{ valid: true, errors: [] }` | Validation state | + +#### Slider + +| Prop | Type | Default | Description | +|------|------|---------|-------------| +| `label` | `string` | `''` | Label text (shows current value) | +| `value` | `number` | `0` | Current slider value | +| `min` | `number` | `0` | Minimum value | +| `max` | `number` | `100` | Maximum value | +| `step` | `number` | `1` | Step increment | +| `validationResult` | `A2uiValidationResult` | `{ valid: true, errors: [] }` | Validation state | + +#### ChoicePicker + +| Prop | Type | Default | Description | +|------|------|---------|-------------| +| `label` | `string` | `''` | Label text above dropdown | +| `options` | `string[]` | `[]` | Available options | +| `selected` | `string` | `''` | Currently selected option | +| `validationResult` | `A2uiValidationResult` | `{ valid: true, errors: [] }` | Validation state | + +#### DateTimeInput + +| Prop | Type | Default | Description | +|------|------|---------|-------------| +| `label` | `string` | `''` | Label text above input | +| `value` | `string` | `''` | Current value | +| `inputType` | `'date' \| 'time' \| 'datetime-local'` | `'date'` | Input type | +| `min` | `string` | `''` | Minimum value | +| `max` | `string` | `''` | Maximum value | +| `validationResult` | `A2uiValidationResult` | `{ valid: true, errors: [] }` | Validation state | + +#### Button + +| Prop | Type | Default | Description | +|------|------|---------|-------------| +| `label` | `string` | `''` | Button text | +| `variant` | `string` | `'primary'` | Visual variant (`'primary'` or `'borderless'`) | +| `disabled` | `boolean` | `false` | Whether the button is disabled | +| `validationResult` | `A2uiValidationResult` | `{ valid: true, errors: [] }` | Validation state (disables when invalid) | + +### Display Components + +#### Text + +| Prop | Type | Default | Description | +|------|------|---------|-------------| +| `text` | `string` | `''` | Text content to display | + +#### Icon + +| Prop | Type | Default | Description | +|------|------|---------|-------------| +| `name` | `string` | `''` | Icon character or emoji | + +#### Image + +| Prop | Type | Default | Description | +|------|------|---------|-------------| +| `url` | `string` | `''` | Image source URL | +| `alt` | `string` | `''` | Alt text for accessibility | + +### Layout Components + +#### Column + +Vertical layout container.

Catch rough edges before the codebase grows further. + +## 1. Type Safety — `surface.component.ts` + +**Problem:** `surfaceToSpec()` uses `Record` for the elements map and several `as any` casts for DynamicValue and child template access. + +**Fix:** +- Replace `Record` with `Record` (import from `@json-render/core`) +- Add a type guard `isDynamicPathRef(value): value is { path: string }` to replace `(value as any).path` casts +- Use `A2uiChildTemplate` type directly for the children template cast (already imported) + +**Scope:** `libs/chat/src/lib/a2ui/surface.component.ts` only.

Public API Exports + +**Problem:** `surfaceToSpec` not exported from `@cacheplane/chat`.

Catalog Component Unit Tests + +**Problem:** Zero unit tests for 18 catalog components.
