Fastify plugins as building blocks for a backend Node.js API

Fastify is a high-performance web framework for building backend Node.js APIs. It offers advantages such as modern ESM support, async/await promise-based route definitions, high performance with fast radix route tree resolution, and a rich plugin architecture with encapsulation. The plugins mentioned in the post, including @fastify/pino, @fastify/cors, @fastify/env, and @fastify/swagger, serve as building blocks for Fastify applications and provide features like logging, CORS support, environment variable management, and API documentation.
