Bun 1.3 introduces unified database APIs (MySQL, PostgreSQL, SQLite), native Redis client 7.9x faster than ioredis, and zero-config frontend development with hot reload.
Key Points
- Bun.SQL provides unified API across MySQL, MariaDB, PostgreSQL, SQLite with zero external dependencies
- Built-in Redis client delivers 7.9x performance improvement over ioredis package
- JavaScript memory usage reduced 10-30% in Next.js and Elysia; bun build 60% faster on macOS
