https://github.com/exelearning/exelearning
2024-11¶
Migration from Symfony/PHP to modern TypeScript stack begins: - Backend rewritten with Elysia + Bun - Database layer migrated to Kysely ORM - Real-time collaboration implemented with Yjs WebSocket
2025¶
Current state:
- Backend: Elysia framework running on Bun runtime
- Database: Multi-database support via Kysely (SQLite, PostgreSQL, MySQL)
- Real-time: Yjs-based collaborative editing with WebSocket
- Testing: 90%+ coverage requirement with Bun test, Vitest, Playwright
- Legacy code: Available in symfony_legacy/ and nestjs_legacy/ for reference
Development Practices¶
- Git workflow: Feature branches merged via Pull Requests
- Testing: Unit (Bun), Integration, Frontend (Vitest), E2E (Playwright)
- Coverage: Minimum 90% for new code
- CI/CD: GitHub Actions for testing and deployment
