Introduction to Fastify
summary
Fastify claims one of the fastest Node.js frameworks with an 89% satisfaction rating and ~800,000 downloads and shows concrete choices: AJV for validation, pino for logging, autoload and a plugin system for encapsulation, and fast JSON stringify for schema-driven serialization that speeds responses. Benchmarks exist but run on GitHub Actions so results may vary. A live coded server, route plugin, autoload wiring, unit-test factory and dot inject tests are built on stage and mostly run after fixing ESM file extension gotchas to achieve zero overhead in production.
