Micro Pico Router

Absolutely minimal, zero-dependency, Node or Micro router.

It allows you to map specific method-endpoint combinations to specific handlers.

Getting Started

npm install --save micro-pico-router

Node HTTP Server Usage

const http = require('http')
const router = require('micro-pico-router')
 
const app = router()
 
app.get('/', (req, res) => {
  res.statusCode = 200
  res.end('okay')
})
 
app.post('/submit', (req, res) => {
  res.statusCode = 200
  res.end()
})
 
// If you not define a default handler it will return status 404 by default
app.default((req, res) => {
  res.statusCode = 404
  res.end('Not Found')
})
 
http.createServer(app).listen(3000)

The previous example, is the same as doing this:

const http = require('http')
const { parse } = require('url')
 
http.createServer((req, res) => {
  const { pathname } = parse(req.url)
 
  if (req.method === 'GET' && pathname === '/') {
    res.writeHead(200, { 'Content-Type': 'text/plain' })
    res.end('Hello!')
  } else if (req.method === 'POST' && pathname === '/submit') {
    res.writeHead(200, { 'Content-Type': 'text/plain' })
    res.end('Thank you for submitting')
  } else {
    res.writeHead(404, { 'Content-Type': 'text/plain' })
    res.end('Not Found')
  }
}).listen(3000)

Micro Usage

const app = require('micro-pico-router')()
 
module.exports = app.get('/', (req, res) => 'Hello!')

Micro with Async

const sleep = require('then-sleep')
const app = require('micro-pico-router')()
 
module.exports = app.get('/', async (req, res) => {
  await sleep(500)
  return 'Ready!'
})

HTTP Methods

The methods available on app[METHOD] are the ones listed by http.METHODS, but lowercased.

You can also give them using the options:

const router = require('micro-pico-router')
 
const app = router({
  methods: ['GET', 'WEIRD']
})
 
app.weird('/', (req, res) => 'Some weird http method!')
