I have followed the basic tutorials (results in one file after you run r.js)
The problem is, my main.js file at the end is 500KB. That's too big. I want to split it into two files.
I want to optimize my main.js file into two files:
- One that holds the front page and user profile pages, since they're most accessed
- One that holds all the other pages (ordering, account settings, profile settings, etc.)
Most people will hit the front page and user profile pages, and I want those to load quickly first (while having the other pages load in the background in the 2nd main file)
The problem is, I don't know how to do this. There are examples like this online, but these examples do not use Backbone. They don't cover how to deal with router and app.js
I'm confused...because I only have one app.js, one router.js...how can I split router.js into two files?
I don't know how to split my project up when dealing with Backbone.
Below is the code
HTML PAGE (the entry point for my Single Page Application)
<html>
<head>
<script type="text/javascript" data-main='/media/js/main' src='/media/js/lib/requirejs/require-jquery.js'></script>
</head>
<body>
Hello
</body>
</html>
Main.js
require.config({

jquery_ui:'lib/jquery-ui/jquery-ui-1.10.3.custom',
underscore: 'lib/underscore/underscore-min',

backbone_viewhelper:'lib/backbone/backbone.viewhelper',
text: 'lib/requirejs/text',
birthdaypicker: 'lib/birthdaypicker/bday-picker',
//more paths
},
waitSeconds: 30,
shim:{
'underscore':{
exports: '_'

'backbone':{
deps:[ 'underscore', 'jquery'],
exports: 'Backbone'
},
'backbone_viewhelper':{
deps:['underscore','backbone']
}
}
});
require([
'app',
'json2',
'jquery_ui',
'backbone_viewhelper',
'bootstrap_js',
'bootstrap_select',
'birthdaypicker',
'accounting',
'numbersonly',

App.initialize();
});
App.js
define([
'jquery',
'underscore',
'backbone',
'router'
], function($, _, Backbone, Router){
var initialize = function(){
Router.initialize();
}
return {
initialize: initialize
};
});
Router.js
define([

var AppRouter = Backbone.Router.extend({
initialize:function(){
_.bindAll(this);
},
routes:{
'':'index',
'home': 'home',

},
index:function(){
app_router_view.show(indexView);
},
search:function(start, num){
var options = {
filters:{
start: start,
num: num
}
};
app_router_view.show(searchView, options);
},
static:function(template){
app_router_view.show(staticView, { static_view: { template: template }});
},
profile:function(){
app_router_view.show(profileView);
},
passResetCode:function(code){
app_router_view.show(passCodeView, {'code':code});
},
//more stuff
home:function(){
app_router_view.show(homeView);
},
defaultAction:function(actions){
this.navigate('/', { trigger:true});
}
});
var initialize = function(){
var app_router = new AppRouter;
Backbone.history.start({pushState:true, root: '/'});
$(document).on('click', 'a:not([data-bypass])', function (evt) {
var href = $(this).attr('href');
if(href){
var protocol = this.protocol + '//';
if (href.slice(protocol.length) !== protocol && href != '#') {
evt.preventDefault();
app_router.navigate(href, { trigger: true});
}
}else{
}
});
};
return {
initialize:initialize
}
});
As you can see , my entire app starts with main.js, goes to app.js, and finally goes to router.js.
How can I split this?
