What is micro?

The 'micro' npm package is a minimalistic framework for creating HTTP microservices. It is designed to be simple, fast, and lightweight, making it ideal for building small, focused services that can be deployed independently.

What are micro's main functionalities?

Basic HTTP Server

This code demonstrates how to create a basic HTTP server using 'micro'. The server listens on port 3000 and responds with 'Hello, world!' to any incoming request.

const { send } = require('micro');
const http = require('http');

const server = http.createServer((req, res) => send(res, 200, 'Hello, world!'));

server.listen(3000, () => console.log('Server running on port 3000'));

Handling JSON Requests

This example shows how to handle JSON requests with 'micro'. The server reads the JSON body of the incoming request and responds with the same data wrapped in an object.

const { json, send } = require('micro');

module.exports = async (req, res) => {
  const data = await json(req);
  send(res, 200, { received: data });
};

Routing with micro-router

This code demonstrates how to use 'microrouter' with 'micro' to handle routing. It defines routes for GET and POST requests to '/hello' and a catch-all route for 404 Not Found responses.

const { send } = require('micro');
const { router, get, post } = require('microrouter');

const hello = (req, res) => send(res, 200, 'Hello, world!');
const notFound = (req, res) => send(res, 404, 'Not Found');

module.exports = router(
  get('/hello', hello),
  post('/hello', hello),
  get('/*', notFound)
);
