REST API libraries and API versioning

In microservices architecture, you can use Node.js frameworks such as Express.js or Fastify to build RESTful APIs and implement API versioning to handle changes and updates to your microservices APIs.

REST API libraries

When building RESTful APIs in Node.js, several libraries simplify the development process, handling routing, request parsing, and response formatting. Here are some commonly used libraries:

• Express: Express.js is a minimalist web framework for Node.js that provides robust routing, middleware support, and an easy-to-use API. The following is an example of using Express.js:

  const express = require('express');

  const app = express();

  app.get('/api/resource', (req, res) => {

    res.send('Hello, API!');

  });

  app.listen(3000, () => {

    console.log('Server is running on port 3000');

  });

• Restify: Restify is designed specifically for building REST APIs and focuses on...
