If you’re an API developer working with Node.js, then you’re probably familiar with Express. But have you tried out the Fastify framework to build with power, speed, and convenience? In this walkthrough, we build a full-featured, easy-to-consume API with Fastify. And we deploy it to the cloud with ease. We show you how to:
- Get started working with Fastify to build an API
- Implement API authentication by using a JSON web token (JWT)
- Use Fastify’s Swagger plugins to generate an OpenAPI specification
- Consume the OpenAPI specification with Postman, giving you an API client that can send requests seamlessly to your back-end API
- Deploy your application to Heroku
