TypeScript Migration Guide

This project now supports TypeScript alongside JavaScript. The migration is gradual and incremental.

Current Status

• ✅ TypeScript configuration files created
• ✅ Type definitions for debug logger
• ✅ allowJs: true - JavaScript files can coexist with TypeScript
• ⏳ Gradual migration in progress

Setup

1. Install TypeScript dependencies:

npm install

2. TypeScript is configured to:
   • Allow JavaScript files (allowJs: true)
   • Not check JavaScript files (checkJs: false)
   • Use strict mode for TypeScript files
   • Support both frontend (React) and backend (Node.js) code

Migration Strategy

Phase 1: New Files (Current)

• New utility files can be written in TypeScript
• Example: server/utils/debugLogger.ts (when ready)

Phase 2: Type Definitions

• Add .d.ts files for existing JavaScript modules
• Example: server/utils/debugLogger.d.ts (already created)

Phase 3: Gradual Migration

• Migrate files one at a time from .js to .ts
• Start with utility files, then move to core logic
• Test after each migration

TypeScript Configuration Files

• tsconfig.json - Main config for frontend and shared code
• tsconfig.server.json - Server-specific config

Benefits

1. Type Safety: Catch errors at compile time
2. Better IDE Support: Autocomplete, refactoring, navigation
3. Documentation: Types serve as inline documentation
4. Refactoring: Safer refactoring with type checking

Next Steps

1. Migrate utility files (e.g., debugLogger.js → debugLogger.ts)
2. Add types to core interfaces (e.g., Agent, Memory, Transaction)
3. Migrate middleware files
4. Migrate agent files
5. Migrate orchestrator and workflow engine

Running TypeScript

• Type checking: npx tsc --noEmit
• Build: npm run build (uses Vite, which handles TypeScript)
• Development: npm run dev (Vite handles TypeScript automatically)
