Fastify is a Node.js web framework engineered for speed. It's 2-3x faster than Express due to architecture choices: schema validation, smart caching, and efficient routing. Used by Uber, Netflix, and fintech platforms. The learning curve is identical to Express (similar API), but Fastify handles 10x more requests/sec. Senior Fastify engineers earn 10-20% premium because they squeeze performance: streaming responses, connection pooling, and sub-millisecond latency. Learning takes 1-2 weeks; production mastery takes 3-6 months. Fastify also teaches HTTP protocol deeply, transferring to any framework.
Fastify is a modern, high-performance Node.js web framework. Unlike Express (which processes requests serially), Fastify is engineered for concurrency and speed: efficient JSON schema validation, smart routing, and streaming response support. It's the framework of choice for performance-critical applications (trading, real-time analytics, high-traffic APIs). Fastify's killer feature: built-in JSON schema validation and OpenAPI doc generation. Define a schema, Fastify validates incoming requests automatically and serializes responses efficiently.
