Fastify is a web framework highly focused on providing the best developer experience with the least overhead and a powerful plugin architecture.
To install Fastify in an existing project as a dependency install with npm:
npm i fastify
- Highly performant: as far as we know, Fastify is one of the fastest web frameworks in town, depending on the code complexity we can serve up to 76+ thousand requests per second.
- Extendible: Fastify is fully extensible via its hooks, plugins and decorators.
- Schema based: even if it is not mandatory we recommend to use JSON Schema to validate your routes and serialize your outputs, internally Fastify compiles the schema in a highly performant function.
- Logging: logs are extremely important but are costly; we chose the best logger to almost remove this cost, Pino!
- Developer friendly: the framework is built to be very expressive and help the developer in their daily use, without sacrificing performance and security.
