Build status

Browser support

Install

$ npm install did-route

Example

var http = require('http')
var did = require('did-route')()
 
// Home
did.get('/', function (req, res) {
  res.end('Welcome to the homepage\n')
})
 
// Item
did.patch('/item/:id([a-f0-9]{16})',
  function (req, res, params) {
    res.end('Updated ' + params.id + '\n')
  }
)
 
http.createServer(function (req, res) {
  // No route has not been registered for
  // this URI and HTTP method.
  if (!did.route(req, res)) {
 
    // A route *has* been registered for this
    // URI, but not for this HTTP method.
    if (did.match(req)) {
      res.statusCode = 405
      res.end()
      return
    }
 
    res.statusCode = 404
    res.end()
  }
}).listen(8080)

Which would result in the following responses:

$ curl http://localhost:8080
> Welcome to the homepage
 
$ curl -X PATCH http://localhost:8080/item/6d80eb0c50b49a5
> Updated 6d80eb0c50b49a5
 
$ curl -iX DELETE http://localhost:8080/item/6d80eb0c50b49a5
> HTTP/1.1 405 Method Not Allowed

Browser

did-route also works in the browser with basically the same API. The only differences are that a) did.get is the only available routing method, and b) route handlers receive just one argument: the params object.

var did = require('did-route')()
 
did.get('/', function () {
  // No request or response in the browser.
})
 
did.get('/:name([a-zA-Z]+)', function (params) {
  // The only argument is the params object.
})
 
did.get('*#/:name([a-zA-Z]+)', function (params) {
  // It's possible to define routes based on
  // the value of location.hash.
})
 
window.onpopstate = function () {
  var path = window.location || '/path/to/page'
  if (!did.route(path)) {
    // Handle 404
  }
}
 
window.onhashchange = function () {
  var includeQueryAndHash = true
  if (!did.route(window.location, includeQueryAndHash)) {
    // Handle 404
  }
}
