If a leaf node changes (e.g., `/foo/bar`), its parent container (`/foo`) has conceptually also changed, because the parent is the map/list containing that value. Therefore, a subscription to a path must notify if: +1. The value at the exact path changes. +2. Any *descendant* path changes (because the container's content changed). +3. Any *ancestor* path changes (because the container itself might have been replaced). + +This aligns with the `subscribe` behavior in Flutter but removes the need for `subscribeToValue` (which attempted to isolate value changes but is semantically ambiguous in a mutable JSON tree). + +**Requirement:** +* Implement `subscribe(path)` to notify on exact, ancestor, and descendant updates. +* Do *not* implement `subscribeToValue`. + +### 1.2 `Subscription` Object Return Type + +**Purpose:** +Instead of returning a simple `Unsubscribe` function, `subscribe` should return a rich `Subscription` object. This provides a more ergonomic API for consumers (like `DataContext` or external frameworks) to manage their connection to the data. + +**Requirement:** +Redesign the `subscribe` return type to match this interface: + +```typescript +export interface Subscription { + /** + * The current value at the subscribed path. + */ + readonly value: T; + + /** + * A callback function to be invoked when the value changes. + * The consumer sets this property to listen for updates. + */ + onChange?: (value: T) => void; + + /** + * Unsubscribes from the data model. + */ + unsubscribe(): void; +} +``` + +The `subscribe` method signature becomes: +```typescript +subscribe(path: string): Subscription +``` + +### 1.3 `dispose(): void` + +**Purpose:** +Cleans up all internal subscriptions. + +**Requirement:** +Add a `dispose` method to prevent memory leaks. + +### 1.4 `DataContext.resolve(value: any): any` + +**Purpose:** +In Flutter, `DataContext` is responsible for parsing expressions (e.g., `${/user/name}`) and executing function calls found within data values. In the Web v0.9 design, this was delegated to `ComponentContext`. + +**Requirement:** +Move `resolve` logic to `DataContext` or expose it via `DataContext` to allow data resolution outside of components (e.g., in Action handlers or other services). This ensures consistent evaluation logic across the application. + +## 2. Implementation Changes (Web Core) + +The following files in `@renderers/web_core/src/v0_9/**` need updates: + +### 2.1 `state/data-model.ts` + +* **Update `subscribe`**: + * Change return type to `Subscription`. + * Remove callback parameter. + * Ensure notification logic walks up the tree (ancestors) and checks for descendants, invoking `onChange` if set on the returned Subscription object. +* **Add `dispose`**. +* **Fix `set`**: Update logic to create arrays for numeric segments (smart intermediate node creation). +* **Fix `parsePath`**: Ensure consistency with Flutter's `DataPath` (handle leading/trailing slashes correctly). + +### 2.2 `state/data-context.ts` + +* **Update `subscribe`**: Forward the `Subscription` from `DataModel`. +* **Add `resolve`**: Move or copy resolution logic (handling paths, literals, and potentially expressions/function calls) from `ComponentContext`. + +### 2.3 `rendering/component-context.ts` + +* **Update `resolve`**: Delegate to `this.dataContext.resolve()` where possible, or align logic. +* **Refactor**: Use the new `Subscription` object if direct subscription is needed (though typically `resolve` handles this). + +### 2.4 `processing/message-processor.ts` & `state/surface-context.ts` + +* Ensure they use the updated `DataModel` API correctly (e.g., calling `.unsubscribe()` on the returned object instead of calling the function directly). + +## 3.

In a JSON tree: +- If a leaf node (child) changes, the parent container has conceptually changed as well. +- Subscribing to a container (Map/List) usually implies an interest in its contents. +- The `subscribeToValue` optimization relies on object identity, which can be misleading if the underlying data structure is mutable or if the update mechanism replaces parent objects (which `DataModel` often does). + +**Proposal:** +Remove `subscribeToValue` and standardize on the behavior of `subscribe` (notifying on ancestor, self, and descendant changes). This aligns the Flutter implementation with the proposed Web v0.9 implementation and the conceptual model of a JSON tree. + +## API Changes + +### 1. Remove `subscribeToValue` + +The `subscribeToValue` method will be deprecated and removed. + +**Before:** +```dart +// Notifies only if value at path changes identity +final valueNotifier = dataModel.subscribeToValue(DataPath('/user/name')); +``` + +**After:** +```dart +// Notifies if value at path, or any parent/child path changes. +// Returns a ValueNotifier which acts as the Subscription object. +// Listeners are added to this returned notifier. +final valueNotifier = dataModel.subscribe(DataPath('/user/name')); +``` + +### 2. Update `subscribe` Behavior (if needed) + +Ensure `subscribe` correctly handles the "container semantics": +- **Ancestor Update:** If `/user` is replaced, listeners at `/user/name` are notified. +- **Descendant Update:** If `/user/name` is updated, listeners at `/user` are notified. +- **Self Update:** If `/user/name` is updated, listeners at `/user/name` are notified. + +The current Flutter implementation of `subscribe` already supports this "bubbling up" notification for descendants. + +## Rationale + +1. **Conceptual Consistency:** A JSON object is a container. Changing a property inside it changes the object's state. Listeners to the object should be notified. +2. **API Simplicity:** Having two subscribe methods with subtle differences confuses consumers and increases the API surface area. +3. **Platform Parity:** Aligning with the Web v0.9 design ensures that A2UI renderers behave consistently across platforms, simplifying cross-platform development and testing. The Web `subscribe` method returns a `Subscription` object with an `onChange` callback property, which is conceptually similar to Flutter's `ValueNotifier` (an object you add listeners to). +4. **Reduced Complexity:** Removes the need for separate subscription maps (`_subscriptions` vs `_valueSubscriptions`) and the complex conditional logic in `_notifySubscribers` to handle them differently. + +## Migration Guide + +Existing usages of `subscribeToValue` should be replaced with `subscribe`. + +**Example Migration:** + +```dart +// OLD +class MyWidget extends StatelessWidget { + @override + Widget build(BuildContext context) { + // Only wanted updates if this specific string changed + return ValueListenableBuilder( + valueListenable: dataModel.subscribeToValue(path), + builder: (context, value, child) => Text(value ??

''), + ); + } +} +``` + +## Impact on Performance + +Replacing `subscribeToValue` with `subscribe` might trigger more frequent notifications for listeners attached to container nodes (Maps/Lists). However, in typical UI patterns: +- Leaf nodes (Strings, Numbers) have no descendants, so behavior is identical. +- Container nodes are usually bound to Lists or Layouts that *need* to update when their children change. +- The `ValueNotifier` in Flutter checks for equality (`==`) before notifying listeners. If the data update results in the same value (e.g. same String), no notification occurs, preserving the optimization where it matters most. diff --git a/specification/v0_9/docs/renderer_alignment_suggestions.md b/specification/v0_9/docs/renderer_alignment_suggestions.md new file mode 100644 index 000000000..ca546487f --- /dev/null +++ b/specification/v0_9/docs/renderer_alignment_suggestions.md @@ -0,0 +1,68 @@ +# Renderer Alignment Suggestions: Web vs. Flutter + +This document outlines opportunities to align the A2UI Web (v0.9) and Flutter renderer architectures.

Unified Component Naming +* **Suggestion:** Rename Flutter's `CatalogItem` to `Component` and `CatalogItemContext` to `ComponentContext`. +* **Winner:** **Web Design** +* **Reasoning:** `Component` is the standard terminology in modern UI development. It makes the concept of composition (e.g., `ButtonComponent`) more intuitive. + +## 2. Surface State Object +* **Suggestion:** Rename Flutter's `GenUiContext` to `SurfaceState`. +* **Winner:** **Web Design** +* **Reasoning:** `Context` is heavily overloaded (especially in Flutter). `SurfaceState` explicitly describes the object: a repository for the DataModel, Component Tree, Theme, and Catalog of a specific surface. + +## 3. Surface Widget Naming +* **Suggestion:** Rename Flutter's `GenUiSurface` widget to `Surface`. +* **Winner:** **Web Design** +* **Reasoning:** The `GenUi` prefix is redundant if namespaced by the package. `Surface` is concise and directly maps to the protocol terminology. + +## 4. Message Typing +* **Suggestion:** Adopt Flutter's sealed class/union pattern for messages in the Web implementation. +* **Winner:** **Flutter Design** +* **Reasoning:** Flutter's typed classes (`CreateSurface`, `UpdateComponents`) provide better type safety and internal dispatch logic compared to raw JSON objects. The Web `A2uiMessageProcessor` should accept these typed objects. + +## 5. Input Property Naming +* **Suggestion:** Rename Flutter's `CatalogItemContext.data` to `ComponentContext.properties`. +* **Winner:** **Web Design** +* **Reasoning:** `properties` (or `props`) clearly distinguishes configuration attributes from the `DataModel` application data. + +## 6. Message Handling Method +* **Suggestion:** Rename Web's `processMessages(messages: [])` to `handleMessage(message)` (singular) to support streaming patterns. +* **Winner:** **Flutter Design** +* **Reasoning:** `handleMessage` is standard for sink/actor patterns and handles individual stream events more naturally. + +## 7. Surface Cleanup Policy +* **Suggestion:** Add `SurfaceCleanupPolicy` to the Web `A2uiMessageProcessor`. +* **Winner:** **Flutter Design** +* **Reasoning:** Flutter explicitly handles memory management (e.g., `keepLatest` vs `manual`). As Web apps grow in complexity, explicit policies will prevent memory leaks in the surface registry. + +## 8. Transport/Controller Abstraction +* **Suggestion:** Introduce a `Controller` layer to the Web design (like Flutter's `GenUiController`). +* **Winner:** **Flutter Design** +* **Reasoning:** The Web design lacks a standardized layer to handle raw LLM text streams (Markdown + JSON). Shared logic for extracting A2UI JSON from a stream should be standardized. + +## 9. High-Level Facade +* **Suggestion:** Introduce a `Conversation` or `Session` class to the Web design. +* **Winner:** **Flutter Design** +* **Reasoning:** Providing a standard class to bind the Controller, Processor, and Transport together simplifies the developer experience. + +## 10. Data Binding Helpers +* **Suggestion:** Centralize helpers like `resolveString` on `ComponentContext`. +* **Winner:** **Web Design** +* **Reasoning:** Web's `context.resolve(val)` pattern is cleaner for component authors than requiring direct interaction with the `DataContext`. + +--- + +## Summary Table + +| Concept | Recommended Name/Design | Source | +| :--- | :--- | :--- | +| **Component Definition** | `Component` | Web | +| **Component Props** | `context.properties` | Web | +| **Surface State** | `SurfaceState` | Web | +| **Surface Widget** | `Surface` | Web | +| **Protocol Messages** | Sealed Classes / Typed Interfaces | Flutter | +| **Stream Parsing** | `GenUiController` | Flutter | +| **Conversation Mgmt** | `GenUiConversation` | Flutter | +| **Cleanup Logic** | `SurfaceCleanupPolicy` | Flutter | diff --git a/specification/v0_9/docs/schema_support.md b/specification/v0_9/docs/schema_support.md new file mode 100644 index 000000000..3b2a341bf --- /dev/null +++ b/specification/v0_9/docs/schema_support.md @@ -0,0 +1,316 @@ +# Schema Support and Inline Catalogs in v0.9 Web Renderers + +**Status:** Draft +**Target Version:** 0.9 + +## Overview + +This document describes the design for implementing schema validation and `inlineCatalogs` support in the A2UI v0.9 web renderers. The goal is to allow `Catalog` and `Component` definitions to be self-describing using Zod schemas. This enables: + +1. **Runtime Validation:** The core framework can validate incoming component properties against their schema during rendering, ensuring robustness. +2. **Capability Discovery:** The client can generate a machine-readable definition of its supported components (including custom ones) to send to the server via `clientCapabilities`. This supports the "Prompt-First" philosophy by allowing the Agent to learn the available tools (components) dynamically. + +## Architecture Changes + +The primary changes involve the `web_core` library, specifically the `Catalog` and `Component` interfaces and the `A2uiMessageProcessor`. + +### 1. Component Interface Update + +The `Component` interface will be updated to include a required `schema` property.

Common Types Definition + +To ensure generated schemas correctly reference shared definitions (like `DynamicString` or `Action`), we will expose a set of standard Zod schemas in `web_core`. + +**File:** `renderers/web_core/src/v0_9/catalog/schema_types.ts` (New) + +```typescript +import { z } from 'zod'; + +// Helper to tag a schema as a reference to common_types.json +export const withRef = (ref: string, schema: T) => { + return schema.describe(`REF:${ref}`); +}; + +export const CommonTypes = { + DynamicString: withRef( + 'common_types.json#/$defs/DynamicString', + z.union([z.string(), z.object({ path: z.string() }) /* ... full definition ... */]) + ), + Action: withRef( + 'common_types.json#/$defs/Action', + z.object({ /* ... */ }) + ), + // ... other common types +}; +``` + +### 3. Core Validation Logic + +Validation will be centralized in the `ComponentContext` (or a helper used by it). When a component is about to be rendered, the framework will validate the raw properties against the component's Zod schema. + +**File:** `renderers/web_core/src/v0_9/rendering/component-context.ts` + +```typescript +export class ComponentContext { + // ... + + validate(schema: z.ZodType): boolean { + const result = schema.safeParse(this.properties); + if (!result.success) { + console.warn(`Validation failed for ${this.id}:`, result.error); + // Logic to handle error (e.g. render error boundary or fallback) + return false; + } + return true; + } +} +``` + +*Note: Strict validation can be toggled. For v0.9, we might log warnings rather than crashing the render to support progressive/partial updates.* + +## Client Capabilities Generation + +The `A2uiMessageProcessor` will provide a method to generate the `a2uiClientCapabilities` object. This process involves transforming the runtime Zod schemas into the specific JSON Schema format required by the A2UI protocol (specifically matching the structure of `standard_catalog.json`). + +### 1. Replicating the Component Schema Format + +The Zod schema defined in a `Component` implementation represents only the **component-specific properties** (e.g., `text`, `variant` for a Text component). It does *not* include the protocol-level fields like `id`, `component`, or `weight`, nor does it explicitly include the `ComponentCommon` mixins. + +To replicate the `standard_catalog.json` format, the generator must **wrap** the converted Zod schema. + +**Transformation Logic:** + +For each component `(name, component)` in a catalog: +1. Convert `component.schema` (Zod) to a JSON Schema object. +2. Wrap it in the standard A2UI envelope structure: + ```json + { + "type": "object", + "allOf": [ + { "$ref": "common_types.json#/$defs/ComponentCommon" }, + { "$ref": "#/$defs/CatalogComponentCommon" }, + { + "type": "object", + "properties": { + "component": { "const": "" }, + // ... properties from Zod conversion ... + }, + "required": ["component", ... ] + } + ], + "unevaluatedProperties": false + } + ``` + +### 2. Generating `anyComponent` + +For validation and inference, a Catalog often defines an `anyComponent` type which is a discriminated union of all available components. While the `a2ui_client_capabilities.json` schema currently defines the `components` map, the server (or the generator) often requires this union for complete validation logic. + +The generator will construct this `oneOf` array dynamically: + +```typescript +const anyComponent = { + "oneOf": [ + { "$ref": "#/components/Text" }, + { "$ref": "#/components/Button" }, + // ... for all components in the catalog + ], + "discriminator": { + "propertyName": "component" + } +}; +``` + +*Note: If the strict `a2ui_client_capabilities.json` schema does not allow arbitrary `$defs` in the `inlineCatalogs` objects, this derived structure serves as the logical model used for server-side validation construction or is added if the schema permits extensions.* + +### 3. Capabilities API + +The method will allow the caller to specify which catalogs should be fully serialized (sent as `inlineCatalogs`). This is useful for sending custom catalogs that the server might not know about, while omitting the schema for the Standard Catalog (sending only its ID) to save bandwidth. + +**File:** `renderers/web_core/src/v0_9/processing/message-processor.ts` + +```typescript +import { zodToJsonSchema } from 'zod-to-json-schema'; +import { Catalog } from '../../catalog/types.js'; + +export interface ClientCapabilitiesOptions { + /** + * A list of Catalog instances that should be serialized + * and sent as 'inlineCatalogs'. + */ + inlineCatalogs?: Catalog[]; +} + +export class A2uiMessageProcessor { + // ... + + getClientCapabilities(options: ClientCapabilitiesOptions = {}): any { + const inlineCatalogsDef = (options.inlineCatalogs || []).map(catalog => { + const componentsSchema: Record = {}; + + for (const [name, comp] of catalog.components) { + // 1.

Zod provides a robust TypeScript-first way to define schemas. +* **Validation:** It handles runtime validation out-of-the-box. +* **Generation:** The `zod-to-json-schema` library allows converting these definitions to JSON Schema. +* **Refs:** To generate schemas that match `standard_catalog.json` (using `$ref` for common types), we will use a convention (like the `withRef` helper above) where specific Zod instances are tagged. The generation logic in `A2uiMessageProcessor` will intercept these tags and output the correct `$ref` string instead of expanding the schema inline. + +### Where should schema validation happen? +Validation should be centralized in the **Core Framework**, specifically within `ComponentContext` or `SurfaceContext`. +* **Why:** This prevents every renderer (Lit, Angular, etc.) from reimplementing validation logic. +* **When:** Validation should ideally occur **during rendering** (lazy validation). This allows the `updateComponents` message to be processed quickly even if some components are temporarily invalid or incomplete (progressive rendering). When `render()` is called for a specific component, `ComponentContext` can check the properties against `component.schema`. +* **Handling Failures:** If validation fails, the component can choose to render a fallback (e.g., an "Error" widget) or log a warning, rather than breaking the entire surface. + +## Implementation Plan + +1. **Dependencies:** Add `zod` and `zod-to-json-schema` to `@a2ui/web_core` dependencies. +2. **Common Schemas:** Create `schema_types.ts` in `web_core` with Zod definitions for `common_types.json` primitives (`DynamicString`, `Action`, etc.), utilizing a tagging mechanism for `$ref` generation. +3. **Interface Update:** Update `Component` interface in `types.ts`. +4. **Standard Catalog Update:** Iterate through all standard components (`Button`, `Text`, etc.) and define their `schema` properties using Zod and the common types. +5. **Capability Generator:** Implement the `clientCapabilities` getter in `A2uiMessageProcessor`, including the logic to transform Zod schemas to JSON schemas with correct references. +6. **Validation:** Add `validate()` method to `ComponentContext` and integrate calls (optional or mandatory) in component implementations. diff --git a/specification/v0_9/docs/web_renderers.md b/specification/v0_9/docs/web_renderers.md new file mode 100644 index 000000000..b1b5d1ce9 --- /dev/null +++ b/specification/v0_9/docs/web_renderers.md @@ -0,0 +1,945 @@ +# Web Renderer v0.9 Design Document + +**Status:** Draft +**Target Version:** 0.9 +**Authors:** Gemini Agent + +## Overview + +This document outlines the design for the v0.9 Web Renderers (Lit and Angular) for A2UI.

DataModel (Core) + +A standalone, observable data store representing the client-side state. It handles JSON Pointer path resolution and subscription management. + +```typescript +// web_core/src/v0_9/state/data-model.ts + +export interface Subscription { + /** + * The current value at the subscribed path. + */ + readonly value: T; + + /** + * A callback function to be invoked when the value changes. + * The consumer sets this property to listen for updates. + */ + onChange?: (value: T) => void; + + /** + * Unsubscribes from the data model. + */ + unsubscribe(): void; +} + +export class DataModel { + /** + * Updates the model at the specific path. + * If path is '/', replaces the entire root. + */ + set(path: string, value: any): void; + + /** + * Retrieves data at a specific path. + * Returns undefined if path does not exist. + */ + get(path: string): any; + + /** + * Subscribes to changes at a specific path. + * Returns a Subscription object that allows access to the current value, + * setting an onChange callback, and unsubscribing. + * + * Notification Behavior: + * The onChange callback (if set) is invoked whenever: + * 1. The value at the exact 'path' changes. + * 2. An ancestor path changes (implying the container of this value changed). + * 3. A descendant path changes (implying the content of this value changed). + * + * This ensures that a subscriber to a container (e.g. '/users') is notified when + * any of its children (e.g. '/users/0/name') are updated. + */ + subscribe(path: string): Subscription; + + /** + * Disposes of the DataModel, clearing all subscriptions. + */ + dispose(): void; +} + +``` + +### 2. SurfaceContext (Core) + +Holds the complete state for a single surface. This acts as the brain for a specific surface, processing messages and exposing state to the renderer. + +```typescript +// web_core/src/v0_9/state/surface-state.ts + +export type ActionHandler = (action: UserAction) => Promise; + +export class SurfaceContext { + readonly id: string; + readonly dataModel: DataModel; + readonly catalog: Catalog; + readonly theme: any; + + constructor( + id: string, + catalog: Catalog, + theme: any, + actionHandler: ActionHandler + ); + + /** + * The ID of the root component for this surface. + */ + get rootComponentId(): string | null; + + /** + * Retrieves the raw component definition (JSON) for a given ID. + */ + getComponentDefinition(componentId: string): ComponentInstance | undefined; + + /** + * Processes a single A2UI message targeted at this surface. + * Updates DataModel or Component definitions accordingly. + */ + handleMessage(message: ServerToClientMessage): void; + + /** + * Dispatches a user action to the registered handler. + */ + dispatchAction(action: UserAction): Promise; +} + +``` + +### 3. DataContext (Core) + +A contextual view of the main `DataModel`, used by components to resolve relative and absolute paths. It acts as a localized "window" into the state. + +```typescript +// web_core/src/v0_9/state/data-context.ts + +export class DataContext { + constructor(dataModel: DataModel, path: string); + + /** + * The absolute path this context is currently pointing to. + */ + readonly path: string; + + /** + * Subscribes to a path, resolving it against the current context. + * Returns a function to unsubscribe. + */ + subscribe(path: string, callback: (value: T) => void): Unsubscribe; + + /** + * Gets a snapshot value, resolving the path against the current context. + */ + getValue(path: string): T; + + /** + * Updates the data model, resolving the path against the current context. + */ + update(path: string, value: any): void; + + /** + * Creates a new, nested DataContext for a child component. + * Used by list/template components for their children. + */ + nested(relativePath: string): DataContext; +} + +``` + +### 4. Catalog & Component (Core Interface) + +The definition of what a Component is, generic over the output type `T` (e.g., `TemplateResult` for Lit). + +```typescript +// web_core/src/v0_9/catalog/types.ts + +/** + * A definition of a UI component. + * @template T The type of the rendered output (e.g. TemplateResult). + */ +export interface Component { + /** The name of the component as it appears in the A2UI JSON (e.g., 'Button'). */ + name: string; + + /** + * The Zod schema describing the **custom properties** of this component. + * This is used for runtime validation and generating machine-readable + * definitions for client capabilities. + */ + readonly schema: z.ZodType; + + /** + * Renders the component given the context. + */ + render(context: ComponentContext): T; +} + +export interface Catalog { + id: string; + + /** + * A map of available components. + * This is readonly to encourage immutable extension patterns. + */ + readonly components: ReadonlyMap>; + + // Note: Functions will also be defined here in future iterations + // readonly functions: ReadonlyMap; +} +``` + +### 5. ComponentContext (Core) + +A generic, concrete class that implements the core logic for property resolution and tree traversal. It is initialized with a callback to trigger the specific renderer's update mechanism. + +```typescript +// web_core/src/v0_9/rendering/component-context.ts + +export interface AccessibilityContext { + /** + * The resolved label for accessibility (e.g., aria-label). + */ + readonly label: string | undefined; + + /** + * The resolved description for accessibility (e.g., aria-description). + */ + readonly description: string | undefined; +} + +export class ComponentContext { + constructor( + readonly id: string, + readonly properties: Record, + readonly dataContext: DataContext, + readonly surfaceContext: SurfaceContext, + private readonly updateCallback: () => void + ) {} + + /** + * The accessibility attributes for this component, resolved from the + * 'accessibility' property in the A2UI message. + */ + get accessibility(): AccessibilityContext { + // Implementation would resolve 'accessibility.label' and 'description' + // using this.resolve() + return { label: undefined, description: undefined }; + } + + /** + * Validates the component properties against its schema. + * Centralizes validation in the core framework to ensure consistency. + */ + validate(schema: z.ZodType): boolean; + + /** + * Resolves a dynamic value (literal, path, or function call). + * When the underlying data changes, it calls `this.updateCallback()`. + */ + resolve(value: DynamicValue | V): V { + // ... + } + + /** + * Renders a child component by its ID. + * 1. Looks up the component definition in SurfaceContext. + * 2. Looks up the Component implementation in the Catalog. + * 3. Validates the component's properties against its schema (Optional/Lazy). + * 4. Creates a new nested ComponentContext, propagating the updateCallback. + * 5. Calls `component.render(childContext)`. + */ + renderChild(childId: string): T | null { + // ... + } + + dispatchAction(action: Action): Promise { + return this.surfaceContext.dispatchAction(action); + } +} + +``` + +### 6. Common Properties Handling + +A2UI distinguishes between two types of "common" properties: + +1. **Core Protocol Properties (e.g., `id`, `accessibility`):** + * These are defined in `common_types.json` and are part of the `ComponentCommon` envelope. + * **Handling:** The Core framework (`A2uiMessageProcessor` / `ComponentContext`) automatically extracts and manages these. + * **Usage:** Components access them via getters on `ComponentContext` (e.g. `context.id`, `context.accessibility`). They do *not* need to define these in their own Zod schema. + +2. **Catalog-Specific Common Properties (e.g., `weight` in Standard Catalog):** + * These are properties that a specific Catalog (like the Standard Catalog) decides to add to all or most of its components. + * **Handling:** Since the Core framework is catalog-agnostic, it does *not* know about these properties. + * **Usage:** Each component MUST explicitly declare these in its Zod schema. To maintain consistency, the Catalog implementation should define a shared Zod schema for these properties and reference it in each component's definition. + +### 7. A2uiMessageProcessor (Core) + +The central entry point. It manages the lifecycle of `SurfaceContext` objects, routing incoming messages to the correct surface and multiplexing outgoing events. + +```typescript +// web_core/src/v0_9/processing/message-processor.ts + +export interface ClientCapabilitiesOptions { + /** + * A list of Catalog instances that should be serialized + * and sent as 'inlineCatalogs' in the capabilities message. + */ + inlineCatalogs?: Catalog[]; +} + +export class A2uiMessageProcessor { + /** + * @param catalogs A map of available catalogs keyed by their URI. + * @param actionHandler A global handler for actions from all surfaces. + */ + constructor( + private catalogs: Map>, + private actionHandler: ActionHandler + ); + + /** + * Generates the `a2uiClientCapabilities` object. + * It transforms runtime Zod schemas from the components into JSON Schema, + * wrapping them in the standard A2UI envelope and resolving references + * to common types. + */ + getClientCapabilities(options: ClientCapabilitiesOptions): any; + + /** + * Processes a list of server-to-client messages. + * For `createSurface`, it instantiates a new `SurfaceContext` with the correct Catalog. + * For other messages, it delegates to the appropriate `SurfaceContext.handleMessage`. + */ + processMessages(messages: ServerToClientMessage[]): void; + + /** + * Gets the SurfaceContext for a specific surface ID. + */ + getSurfaceContext(surfaceId: string): SurfaceContext | undefined; +} + +``` + +### 8. Schema Validation and Capabilities (Core) + +v0.9 introduces formal schema support using Zod. This enables automated runtime validation of component properties and machine-readable capability discovery. + +**Key Concepts:** + +1. **Common Types Definition:** + The `web_core` library exposes a `CommonTypes` object containing Zod definitions for standard A2UI types (e.g., `DynamicString`, `Action`). These definitions are crucial for two reasons: + * **Runtime Validation:** They enforce structure (e.g., that an Action has an event name). + * **Reference Tagging:** Each common type is tagged with a special description (e.g., `.describe('REF:common_types.json#/$defs/DynamicString')`). This allows the capability generator to identify them. + +2. **Component Schema Definition:** + Each component defines a `schema` property using Zod. Developers must use the schemas from `CommonTypes` rather than redefining them. This ensures that the generated capabilities correctly reference the shared definitions instead of inlining verbose duplicates. + + ```typescript + // standard_catalog/components/button.ts + const buttonSchema = z.object({ + label: CommonTypes.DynamicString, // Uses the tagged schema + action: CommonTypes.Action + }); + ``` + +3. **JSON Schema Generation & Post-Processing:** + The `A2uiMessageProcessor.getClientCapabilities()` method performs a multi-step transformation: + * **Conversion:** It uses `zod-to-json-schema` to convert the component's Zod schema into a standard JSON Schema. + * **Envelope Wrapping:** It wraps the property schema in the standard A2UI envelope (including `allOf` references to `ComponentCommon` and `CatalogComponentCommon`), ensuring the output structure matches `standard_catalog.json`. + * **Reference Resolution:** It recursively traverses the generated JSON Schema. When it encounters a node with a description starting with `REF:`, it replaces that entire node with a `{ "$ref": "..." }` object using the path provided in the tag. This ensures the output is compact and modular, referencing `common_types.json` as required by the spec. + +4. **Runtime Validation:** + During rendering, the `ComponentContext.validate()` method uses the Zod schema to check the raw properties received from the server. This provides immediate feedback on malformed messages. + +### 9. Standard Catalog Components (Core & Frameworks) + +To reduce code duplication between Lit and Angular, we define concrete, generic component classes in Core that handle the protocol logic and delegate rendering via a functional interface (composition). This example illustrates the pattern using the **Button** component. + +#### A. Core Logic (Generic) +Location: `@a2ui/web_core/src/v0_9/standard_catalog/components/button.ts` + +```typescript +import { Component } from '../../catalog/types'; +import { ComponentContext } from '../../rendering/component-context'; + +export interface ButtonRenderProps { + childContent: T | null; + variant: 'primary' | 'borderless' | 'default'; + disabled: boolean; + onAction: () => void; +} + +export class ButtonComponent implements Component { + readonly name = 'Button'; + + constructor(private readonly renderer: (props: ButtonRenderProps) => T) {} + + render(context: ComponentContext): T { + const { properties } = context; + const childId = properties['child'] as string; + const variant = (properties['variant'] as string) || 'default'; + const isEnabled = context.resolve(properties['enabled'] ?? true); + const action = properties['action']; + + const onAction = () => { + if (isEnabled && action) { + context.dispatchAction(action); + } + }; + + return this.renderer({ + childContent: context.renderChild(childId), + variant: variant as any, + disabled: !isEnabled, + onAction + }); + } +} +``` + +#### B. Lit Implementation +Location: `@a2ui/lit/src/v0_9/standard_catalog/components/button.ts` + +```typescript +export const litButton = new ButtonComponent( + (props: ButtonRenderProps) => html` + + ` +); +``` + +#### C. Angular Implementation +Location: `@a2ui/angular/src/lib/v0_9/standard_catalog/components/button.ts` + +```typescript +export const angularButton = new ButtonComponent( + (props: ButtonRenderProps) => ({ + componentType: NgButtonComponent, + inputs: { variant: props.variant, disabled: props.disabled, child: props.childContent }, + outputs: { action: props.onAction } + }) +); +``` + + +### 10. Lit Renderer Implementation Example + +This example demonstrates how the Lit implementation of the Surface component orchestrates the rendering process, including creating the `ComponentContext` with the necessary callbacks. + +```typescript +// @a2ui/lit/src/v0_9/ui/surface.ts + +@customElement('a2ui-surface') +export class Surface extends LitElement { + @property({ attribute: false }) + state?: SurfaceContext; + + // Reactivity: Subscribe to SurfaceContext changes (or DataModel changes) + // Since we pass 'this.requestUpdate' to the context, components will call it when data changes. + + render() { + if (!this.state || !this.state.rootComponentId) return nothing; + + // 1. Get Root Definition + const rootId = this.state.rootComponentId; + const rootDef = this.state.getComponentDefinition(rootId); + if (!rootDef) return nothing; + + // 2. Create Context + // We pass a bound version of requestUpdate so components can trigger re-renders. + const context = new ComponentContext( + rootId, + rootDef.properties, + new DataContext(this.state.dataModel, rootDef.dataContextPath ?? '/'), + this.state, + () => this.requestUpdate() + ); + + // 3. Render Root + const component = this.state.catalog.components.get(rootDef.type); + if (!component) return html`Unknown component: ${rootDef.type}`; + + return component.render(context); + } +} +``` + +### 11. SurfaceRenderer (Framework Specific) + +The `SurfaceRenderer` (typically exported as `Surface`) is the top-level component that users place in their applications. It serves as the gateway between the framework's DOM and the A2UI state. + +```typescript +// Interface for the component's inputs +export interface SurfaceProps { + /** + * The complete state for this surface, obtained from A2uiMessageProcessor. + */ + state: SurfaceContext; +} +``` + +**Responsibilities:** +1. **Reactivity**: It observes the `SurfaceContext`. When the `rootComponentId` changes, or when component definitions are updated, it triggers a re-render. +2. **Theming**: It reads `SurfaceContext.theme` and applies it to the surface container, typically by generating CSS Custom Properties (variables) like `--a2ui-primary-color`. +3. **Root Orchestration**: It identifies the component definition for 'root', instantiates the framework-specific `ComponentContext`, and calls the root component's `render()` method. +4. **Error Boundaries**: It provides a top-level catch for rendering errors within the surface. + +## Detailed File Structure + +### Web Core (`@a2ui/web_core`) + +```text +src/ + v0_9/ + index.ts # Public API exports + types/ + messages.ts # TS interfaces for JSON schemas + common.ts + state/ + data-model.ts # DataModel implementation + data-model.test.ts + surface-state.ts # SurfaceContext implementation + data-context.ts # DataContext implementation + processing/ + message-processor.ts # A2uiMessageProcessor + message-processor.test.ts + catalog/ + types.ts # Component, Catalog interfaces + catalog-registry.ts # Helper to manage multiple catalogs + rendering/ + component-context.ts # ComponentContext implementation + standard_catalog/ + factory.ts # Strict catalog factory + components/ # Generic component classes + text.ts + card.ts + button.ts + ... + functions/ # Standard function implementations (pure JS/TS) + logic.ts + formatting.ts +``` + +### Lit Renderer (`@a2ui/lit`) + +```text +src/ + v0_9/ + index.ts # Public exports + renderer/ + lit-component-context.ts # Implementation of ComponentContext + lit-renderer.ts # Orchestrates rendering a Surface + standard_catalog/ + index.ts # Exports the catalog definition + components/ # Concrete implementations of standard components + text.ts # Concrete implementation extending TextBaseComponent + card.ts + ... + ui/ + surface.ts # custom element +``` + +### Angular Renderer (`@a2ui/angular`) + +```text +src/ + lib/ + v0_9/ + index.ts + renderer/ + angular-component-context.ts + renderer.service.ts + standard_catalog/ + index.ts # Exports the catalog definition + components/ # Concrete Angular components for standard catalog + text.component.ts + card.component.ts + ... + ui/ + surface.component.ts +``` + + +### Binding to A2UI (Catalog Registration) + +To ensure consistency across different renderers, `@a2ui/web_core` provides a strict interface and a factory function. This enforces that every renderer implements the full set of components required by the A2UI Standard Catalog. + +#### 1. Core Factory Utility +Location: `@a2ui/web_core/src/v0_9/standard_catalog/factory.ts` + +```typescript +import { Component, Catalog } from '../catalog/types'; + +/** + * Strict contract for the Standard Catalog. + * Add all standard components here to enforce implementation in all renderers. + */ +export interface StandardCatalogComponents { + Button: Component; + Text: Component; + Column: Component; + Row: Component; + // ... other standard components +} + +export function createStandardCatalog( + components: StandardCatalogComponents +): Catalog { + const componentMap = new Map>( + Object.entries(components) as [string, Component][] + ); + + return { + id: 'https://a2ui.org/specification/v0_9/standard_catalog.json', + components: componentMap + }; +} +``` + +#### 2. Framework Usage (Lit Example) +Location: `@a2ui/lit/src/v0_9/standard_catalog/index.ts` + +```typescript +import { createStandardCatalog } from '@a2ui/web_core/v0_9/standard_catalog/factory'; +import { litButton } from './components/button'; +import { litText } from './components/text'; + +export function createLitStandardCatalog(): Catalog { + // TypeScript will enforce that all components defined in + // StandardCatalogComponents are provided here. + return createStandardCatalog({ + Button: litButton, + Text: litText, + Column: litColumn, + Row: litRow, + }); +} +``` + +### Creating a Custom Catalog + +Developers can create custom catalogs by combining the standard catalog with their own components. This is done by creating a new `Catalog` implementation that merges the standard component map with custom definitions. + +```typescript +// my-app/src/custom-catalog.ts + +import { createLitStandardCatalog } from '@a2ui/lit'; +import { Catalog, Component } from '@a2ui/web_core/v0_9/catalog/types'; +import { html, TemplateResult } from 'lit'; +import { ComponentContext } from '@a2ui/web_core/v0_9/rendering/component-context'; + +// 1. Define a Custom Component +class MyCustomComponent implements Component { + readonly name = 'MyCustomComponent'; + + // Define schema for properties. + // Common types like DynamicString are tagged to generate $refs in capabilities. + readonly schema = z.object({ + title: CommonTypes.DynamicString.describe('The title for the special widget') + }); + + render(context: ComponentContext): TemplateResult { + const title = context.resolve(context.properties['title'] ?? 'Custom'); + return html`
Special: ${title}
`; + } +} + +// 2. Create the Custom Catalog +export function createMyCustomCatalog(): Catalog { + // Start with the standard catalog + const standardCatalog = createLitStandardCatalog(); + + // Create a new map seeded with standard components + const components = new Map>( + standardCatalog.components + ); + + // Add (or override) components + components.set('MyCustomComponent', new MyCustomComponent()); + + return { + id: 'https://myapp.com/catalog/v1', + components + }; +} +``` + +## Renderer Output Formats & Resolution + +### Lit +* **Output Format (`T`):** `TemplateResult` (from `lit-html`). +* **Dynamic Resolution:** `LitComponentContext.resolve()` uses `@lit-labs/signals` or a similar mechanism to create a signal that updates when the underlying `DataModel` path changes. The `render` method of the component will effectively be a computed signal. + +### Angular +* **Output Format (`T`):** This is trickier in Angular. The "Render" function for an Angular component in this design is actually a factory or a configuration that the `Surface` component uses to dynamically spawn `NgComponentOutlet` or `ViewContainerRef`. + * *Proposed:* `T` is an object: `{ type: Type, inputs: Record }`. + * The `AngularStandardCatalog` returns a mapping to actual Angular Components (`@Component`). + * The `render` function in the `Component` interface calculates the inputs based on the context. + +## Testing Plan + +1. **Core DataModel**: + * Test `set`/`get` with simple values, objects, and arrays. + * Test `subscribe` triggers correctly for direct updates, parent updates, and child updates. +2. **Core MessageProcessor**: + * Test processing `createSurface`, `updateComponents`, `updateDataModel`. + * Verify internal state matches the message sequence. +3. **Core Standard Catalog Bases**: + * Unit test property parsing and validation logic independent of rendering. +4. **Framework Renderers**: + * **Isolation**: Test individual components (e.g., Lit `Text` component) by passing a mock `ComponentContext`. Verify the output HTML/Template. + * **Integration**: Test `Surface` component with a real `A2uiMessageProcessor` and a mock Catalog. Feed it JSON messages and verify the DOM structure. + +## Implementation Phasing + +1. **Phase 1: Core Foundation** + * Implement `DataModel` with tests. + * Implement `A2uiMessageProcessor` (skeleton handling messages) with tests. + * Define `Component`, `Catalog`, `ComponentContext` interfaces. + +2. **Phase 2: Standard Catalog Components (Core)** + * Implement `StandardCatalog` generic component classes in Core for 2-3 components (e.g., `Text`, `Column`, `Button`). + * Implement standard functions logic (string interpolation etc). + +3. **Phase 3: Lit Prototype** + * Implement `LitComponentContext`. + * Implement `LitStandardCatalog` in the `standard_catalog` directory for the initial 2-3 components. + * Implement `` that connects the Processor to the rendering logic. + +4. **Phase 4: Angular Prototype** + * Implement `AngularComponentContext`. + * Implement `AngularStandardCatalog` in the `standard_catalog` directory and corresponding Angular Components. + * Implement `` for Angular. + +5. **Phase 5: Full Standard Catalog** + * Flesh out the rest of the components (Inputs, Lists, etc.) in Core and both renderers. + +## Open Questions & Answers + +* **Q: Should the surface and a2uimessageprocessor both accept the catalogs?** + * **A:** No. `A2uiMessageProcessor` accepts the registry of Catalogs. When `createSurface` is processed, the Processor creates a `SurfaceContext` and injects the specific `Catalog` required for that surface. The `Surface` component then accepts the `SurfaceContext` as input, giving it access to everything it needs (DataModel, Catalog, Event Dispatcher). + * *Decision:* `A2uiMessageProcessor` holds the registry. `SurfaceContext` holds the specific instance. `Surface` (Renderer) takes `SurfaceContext`. + +* **Q: API for resolving DynamicString?** + * **A:** `ComponentContext.resolve(value: DynamicValue): T`. This method encapsulates checking if it's a literal, a path (calling DataModel), or a function (executing logic). + +* **Q: DataModel API?** + * **A:** See "API Design > DataModel". It mimics a simplified deep-observable object store. + +* **Q: Renderer Output Format?** + * **A:** Lit: `TemplateResult`. Angular: `{ component: Type, inputs: Record }` (Representation of a dynamic component). + +## Standard catalog implementation + +There will be a standard catalog implementation, decoupled from the core renderer in a folder like standard_catalog which has an implementation of the standard catalog. + +So in the framework-specific catalog renderers, the standard catalog implementation should be clearly separated from the rendering framework, in the same way as the web core codebase. This is achieved by having the generic logic in Core and the framework-specific rendering functions in the renderer packages. + +The standard catalog implementation for each framework will reside in a `standard_catalog` directory within the framework's package. This directory will export the catalog definition and contain the concrete implementations of the standard components. + +## Renderer Structure Differences: v0.8 vs v0.9 + +This section outlines the architectural and structural differences between the existing v0.8 A2UI web renderers and the proposed v0.9 design. + +### 1. Codebase Structure & Responsibilities + +* **v0.8 (Current)**: + * **Core**: Contains types and basic message processing. Logic is scattered. + * **Renderers**: Hold the bulk of the logic and strictly typed component nodes. +* **v0.9 (Proposed)**: + * **Core**: Becomes the "Brain", handling State (`DataModel`, `SurfaceContext`) and Base Logic (Generic `ButtonComponent`, `TextComponent`, etc. which handle protocol tasks). + * **Renderers**: Become thinner "View" layers, implementing `ComponentContext` and providing concrete renderer functions for standard components. + +### 2. Component Implementation & "Node" Intermediate Representation + +* **v0.8**: Uses a two-step process: Decode JSON to strict `AnyComponentNode` tree -> Render. Adding a component requires updating Core types. +* **v0.9**: Removes the "Node" IR. Components access raw JSON properties via `ComponentContext`. Logic is driven by the component implementation itself, making the core framework extensible without type changes. + +### 3. Custom Components & Catalog Management + +* **v0.8**: Uses a singleton registry or static maps. Hard to scope components per surface. +* **v0.9**: Introduces `Catalog` instances. A `Surface` is initialized with a specific `Catalog`, allowing easy scoping and composition. + +**Example: Adding a "Map" component by extending the standard catalog** + +```typescript +import { createLitStandardCatalog } from '@a2ui/lit'; +import { MapComponent } from './my-map-component'; + +const standardCatalog = createLitStandardCatalog(); +const components = new Map(standardCatalog.components); + +// Add custom component +components.set('Map', new MapComponent()); + +const myAppCatalog: Catalog = { + id: 'https://myapp.com/catalog', + components +}; + +processor.registerCatalog(myAppCatalog); +``` + +### 4. Data Binding & State + +* **v0.8**: Data managed as a flat map. Binding logic manual in components. Reactivity implicit. +* **v0.9**: Data managed by `SurfaceContext` -> `DataModel`. Components use `context.resolve(value)` which automatically subscribes the rendering context to the specific data path, ensuring precise updates. + +### Summary Table + + + +| Feature | v0.8 | v0.9 | + +| :------------------ | :------------------------------------------ | :----------------------------------- | + +| **Parsing** | JSON -> `AnyComponentNode` (Typed) | JSON -> Schema Validated (Zod) | + +| **Component Logic** | Duplicated in Renderers | Centralized in Core Generic Classes | + +| **Registry** | Singleton / Static Map | `Catalog` Interface (Instance based) | + +| **Extensibility** | Register globally | Compose/Wrap Catalog objects | + +| **State Scope** | Global (mostly) | Scoped to `SurfaceContext` | + +| **Surface Entry** | `` | `` | + + + +## References + + + +* **v0.9 Spec:** `@specification/v0_9/**` + +* **Schema Support Design:** `schema_support.md` + +* **Existing Lit Renderer:** `@renderers/lit/**` + +* **Flutter Catalog Implementation:** `genui` package (reference for catalog patterns). + +
