Fastify Fundamentals: Building Your First Route
Fastify is a robust framework for Node.js developers to build neat, secure, and scalable applications. It has internal infrastructure to help with logging, testing, and error handling.
In this blog, we will teach you how to use factories and plugins, and how to handle environment variables while building your applications.
