Fastify and Express are both great API frameworks for Node.js. Which one you choose will depend on your specific needs and preferences. If performance is a top priority and you need built-in support for data validation and serialization, Fastify may be the better choice. If simplicity and a large ecosystem of third-party middleware packages is more important, then Express may be the way to go.
