This introduces the complete architecture documentation for Iris Apps, a revolutionary system where apps are developed inside Iris, expose tools to AI agents, and can run standalone or be shared with others. Documents included: - Vision: Philosophy and goals for the system - Architecture: System components and their interactions - App Model: App structure, lifecycle, and configuration - SDK Design: APIs for server and React client - Security Model: Permissions, sandboxing, and audit logging - Resilience: Error handling and development experience - Protocol: Communication protocols between components - Implementation Roadmap: Phased approach with milestones Key innovations: - Self-hosted development (build apps inside Iris) - AI-native tools as first-class citizens - Graceful error handling during development - Three modes: development, installed, standalone - Robust permission and security model
- Make Server-Defined Rendering (SDR) the primary approach - Keep iframes as escape hatch for custom UI mode (3D, canvas, etc.) - Simplify single-file app model (app.json + server.ts) - Update security model with VS Code-like trust levels - Revise protocol for SDR component trees and actions - Update implementation roadmap for simpler SDR-based phases - Add React Native component registry for mobile support
Phase 1 implementation of the Iris Apps system: Backend (src/apps/): - types.ts: Core types, manifest schema, SDR message types - manager/: App discovery, loading, lifecycle management - runtime/: App execution, state management, hot reload SDK packages (packages/): - @iris/app-sdk: defineApp, defineTool, state primitives - @iris/ui: Component functions (Stack, Button, Input, etc.) Frontend (webui/src/components/apps/): - SDRRenderer: Renders component trees to React - AppHost: Manages WebSocket connection and error handling Demo app (examples/counter-app/): - Complete counter app showcasing SDR architecture - Tools exposed for AI agent integration - State management with history tracking This implements the foundation for the SDR-first architecture where apps are single-file TypeScript modules with state, tools, and ui(). TODOs remaining: - Wire up WebSocket handlers - Integrate with existing Iris routes - Add proper hot reload debouncing - Implement remaining specialized components
API Routes (src/server/routes/apps.ts): - GET /api/projects/:projectId/apps - List apps in project - GET /api/projects/:projectId/apps/:appId - Get app details - POST /api/projects/:projectId/apps/:appId/activate - Activate app - POST /api/projects/:projectId/apps/:appId/deactivate - Deactivate app - POST /api/projects/:projectId/apps/:appId/reload - Hot reload app - POST /api/projects/:projectId/apps/:appId/action - Execute action - GET /api/projects/:projectId/apps/:appId/ui - Get current UI tree WebSocket Protocol: - app.subscribe - Subscribe to app UI updates - app.unsubscribe - Unsubscribe from app updates - app.action - Execute an action (tool call) - app.activate - Activate an app - app.deactivate - Deactivate an app - app.reload - Trigger hot reload Events: app.ui.sync, app.ui.patch, app.state.update, app.error, etc. Hot Reload (src/apps/hot-reload.ts): - Debounced file watching (150ms default) - Configurable file extensions and ignore patterns - State preservation across reloads Wired into existing Hono app and WebSocket handler registry.
