uWestJS

uWestJS v2.0.1 is a high-performance platform adapter for NestJS powered by uWebSockets.js, providing HTTP and WebSocket capabilities with up to 4-5x faster performance than Express and 2-2.5x faster than Fastify. It maintains full compatibility with NestJS decorators and patterns, supports native backpressure handling, built-in compression, and streaming. Notable for its low memory footprint and ability to handle thousands of concurrent connections. Built specifically for Node.js >=24, it ships with full TypeScript types and supports NestJS v9-11. Its key differentiator is bringing uWebSockets.js performance to NestJS without requiring code changes.
