find-my-way

A crazy fast HTTP router, internally uses an highly performant Radix Tree (aka compact Prefix Tree), supports route params, wildcards, and it's framework independent.
It is inspired by the echo router, some parts have been extracted from trekjs router.

Install

npm i find-my-way --save

Usage

const http = require('http')
const router = require('find-my-way')()

router.on('GET', '/', (req, res, params) => {
  res.end('{"hello":"world"}')
})

const server = http.createServer((req, res) => {
  router.lookup(req, res)
})

server.listen(3000, err => {
  if (err) throw err
  console.log('Server listening on: http://localost:3000')
})

API

FindMyway([options])

Instance a new router.
You can pass a default route with the option defaultRoute.

const router = require('find-my-way')({
  defaultRoute: (req, res) => {
    res.statusCode = 404
    res.end()
  }
})

on(method, path, handler, [store])

router.on('GET', '/', (req, res, params) => {
  // your code
})

// with store
router.on('GET', '/store', (req, res, params, store) => {
  // the store can be updated
  assert.equal(store, { hello: 'world' })
}, { hello: 'world' })

If you want to register a parametric path, just use the colon before the parameter name, if you need a wildcard use the star.

// parametric
router.on('GET', '/example/:name', () => {}))
// wildcard
router.on('GET', '/other-example/*', () => {}))

lookup(request, response)

Start a new search, request and response are the server req/res objects.
If a route is found it will automatically called the handler, otherwise the default route will be called.
The url is sanitized internally, all the parameters and wildcards are decoded automatically.

router.lookup(req, res)

find(method, path)

Return (if present) the route registered in method:path.
The path must be sanitized, all the parameters and wildcards are decoded automatically.

router.find('GET', '/example')
// => { handler: Function, params: Object, store: Object}
// => null
