RequireJS, Load timeout for modules!

Working with BackboneJS, will make you work with RequireJS. And if you are working with BackboneJS for a little time, then you probably know what I am talking about. Sometimes, the modules we are loading through RequireJS throw errors saying

Error: Load timeout for modules

I will suggest to have a look at RequireJS documentation for detailed explanation.
The most common and which may hit you in the begining is the timeout for timeout itself. There are ways to fix this. The options are

• increase the timeout limit
• reload the page or the module on timeout error

The RequireJS configuration has an option called waitSeconds, which defaults to 7. Now if the module does not load in 7 seconds, it will giveup and throw the error. If waitSeconds is set to 0, it will wait for infinite. Well, along with that setting, set the enforceDefine to true for reliability in all browsers and scenarios. This setting will look as below.

requirejs.config({
    enforceDefine: true,
    waitSeconds: 0,

Thats a quickfix. But again, it may hit the performace of the application.
The otherway is Errbacks as per RequireJS. so what are they. They are simply callbacks but since it happens in errors, its called Errbacks. We can do stuff like reloading the whole application or the specified module or other error handling on these.

require(['modules/one','modules/two'],
           function(One,Two){
            //Application logic
        },
        function(error){
            console.log('Custom ERROR handler',error);
            //error.requireModules : is Array of all failed modules
            var failedId = error.requireModules && error.requireModules[0];
            console.log(failedId);
            console.log(error.message);
        });

Happy Coding.
