使用requirejs扩展Web应用程序

Question

I am building a js application based on RequireJs. Everything is working fine except one thing, after compiling it with r.js application is around 2.5Mb. And it does not have yet all the functionality available, i mean there is still room to work inside. And i am afraid that the compiled js file will be over 5Mb and mobile users might face some challenges on slow internet connection.

So my question is:

Is this normal to have such big files on very large js applications? Or should i split it on smaller applications/modules?

Answer 1

I would really recommend splitting that large file in modules/files. Data transfer is not much of an issue nowadays but still, this could mean some really performance issues for some users that still dont have access to fast networks. You should check what resources you need in order to bootstrap your app and have them loaded first, and everything else should be loaded on demand as you need them. Requirejs is a really good approach.
