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

require([

app_router_view.show(searchView, options);
},

app_router_view.show(staticView, { static_view: { template: template }});
},

app_router_view.show(profileView);

},
//more stuff

app_router_view.show(homeView);
},

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?
