Fastify Workshop

Fastify is a web framework designed to build APIs and servers for Node.js. It is known for its speed, security, and developer-friendly experience.

Fastify was created by Matteo Collina in 2016.

You should use Fastify because it is highly performant, secure, extensible through plugins, and offers a great developer experience with features like JSON schema support and logging by default.

Core features of Fastify include high performance with almost no overhead, extensibility through plugins and hooks, JSON schema support, default logging using Pino, and a welcoming community.

Fastify uses a logger called Pino, which is fast and efficient. Logging can be configured with options like PrettyPrint for human-readable logs.

Fastify uses AJV for JSON schema validation and serialization, which ensures high performance by compiling request and response schemas.

You can test Fastify applications using tools like 'tap' and 'C8' for code coverage. Fastify's inject function allows you to simulate HTTP requests for testing purposes.

Fastify JWT is a plugin for handling JSON Web Tokens (JWT) authentication. It is used to generate and verify JWTs, enabling secure authentication for your Fastify applications.

You can manage configuration using environment variables and the 'env-schema' module, which allows you to define and validate configuration through JSON schemas.

Fastify uses decorators to extend functionality and hooks to execute code at specific points in the request lifecycle, such as onRequest, preValidation, and preHandler hooks.

Fastify Auto-Load is a module that automatically registers plugins and routes from specified directories, simplifying the organization and scalability of your application.

Fastify fully supports TypeScript. You can define schemas using tools like TypeBox and add custom types through declaration merging to ensure type safety and autocompletion.
