Quick Start

1. Add a new route

   edmond.addRoute('/users/:id', function(request) {
    
     // Do something...
    
   });

2. Listen to the ‘error’ event

   edmond.on('error', function(message) {
    
     // Do something...
    
   });

3. Dispatch the route

   edmond.dispatchRoute('/users/123');

   Please see the Tips section for more information about implementing HTML5 history.

Tips

HTML5 History

1. First of all, we need to add a new event listener

   window.addEventListener('popState', function() {
     edmond.dispatchRoute(window.location.pathname);
   });

2. Secondly, add a new event listener to the dispatch event

   edmond.on('dispatch', function(path) {
     history.pushState({}, null, path);
   });

Methods

• addRoute
• dispatchRoute
• on

Objects

• request

AddRoute

addRoute(route, fn1[, fn2, fn3, ...])

In route you can use placeholders (for instance :username) which are then available as request.params.

The callback fn gets two arguments request and next where request is a request object (see request for more information) and the second argument next allows you to move to the next callback (if defined).

Example

edmond.addRoute('/users/:username', function(request, next) {
 
  alert('Hello ' + request.username + '!');
 
});

DispatchRoute

dispatchRoute(path)

Example

edmond.dispatchRoute('/users/123/delete');

On

on(event, listener)
