Backbone.Highway - Routing Backbone with style \o/

Backbone.Highway wraps the Backbone.Router to simplify its use and bring new functionalities.

This is a simplified version of the previous Backbone.Highway library completely re-written in ES2015.

Added functionalities compared to the Backbone.Router are:

  • Named routes
  • Special error routes 404
  • Event triggers distributed using an event aggregator

Installation

For now this version of Backbone.Highway is not distributed on npm or bower. But you can install it directly from gihub using any package manager.

npm i --save git+ssh://git@github.com/d4f/highway.git

or

bower i --save git+ssh://git@github.com/d4f/highway.git

Getting started

Simply declare some routes using the highway.route() method and then start the router with the highway.start() method.

import $ from 'jquery';
import highway from 'backbone-highway';

// Declare a home route
highway.route({
  name: 'home', // The name of the route
  path: '/', // The url to which the route will respond

  // Method to be executed when the given path is intercepted
  action() {
    // Do something fantastic \o/
  }
});

// Declare a user profile route
highway.route({
  name: 'profile',
  path: '/users/:id',
  action(id) {
    // Render user profile page using id parameter
  }
});

// Wait for document ready event
$(() => {
  // Start the router
  highway.start();
});

Navigating

Use the go method to navigate to a declared route

// Navigate to simple route using its name
highway.go('home');

// Navigate to route with parameters
highway.go({ name: 'profile', params: [42] });
// `params` can be called `args` aswell
highway.go({ name: 'profile', args: [42] });

// Navigate using url
highway.go({ path: '/users/42' });

Catching client-side 404

You can declare a special route named 404 to catch inexisting routes

highway.route({
  name: '404',
  action() {
    // Display 404 error page
  }
});

Events

Each route can trigger events using an event aggregator like Backbone.Events or Backbone.Radio

import $ from 'jquery';
import highway from 'backbone-highway';
import { Events } from 'backbone';

// Listen to 'core:render' event
Events.on('core:render', (name) => {
  console.log(`Hello ${name} from 'core:render' event!`);
});

// Declare a profile route
highway.route({
  name: 'profile',
  path: '/users/:name',
  // Declare events that will be triggered before the `action`
  events: [
    'core:render' // An event can be a simple string
    { name: 'core:render', params: ['World'] } // Or an object to pass in specific parameters
    { name: 'core:render', args: ['Arg World'] } // Same as above with `args` instead of `params`
  ],
  action(name) {
    console.log(`Hello ${name} from route action!`);
  }
});

// Wait for document ready
$(() => {
  // Start the router passing the event aggregator instance in the `dispatcher` option
  highway.start({ dispatcher: Events });

  // Navigate to the route
  highway.go({ name: profile, params: ['Highway'] });
});

In this example, the route parameter :name will be passed to the event, but it can be overridden by declaring specific params for the event.
