Fastify

These are the main features and principles on which fastify has been built:

• 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 30 thousand requests per second.
• Extensible: 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 to help developers in their daily use, without sacrificing performance and security.
• TypeScript ready: we work hard to maintain a TypeScript type declaration file so we can support the growing TypeScript community.
