Can i divide index.html file into different files in angularjs

Question

Hi i have now a big project done in angularjs and my index.html file starts to be very long :

<!DOCTYPE html>
<html class="no-js">

<head>
<title>InTouch</title>

<base href="/">
<meta charset="utf-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="viewport" content="width=device-width, initial-scale=1">

<!-- Bootstrap -->
<link rel="stylesheet" href="bootstrap/css/bootstrap.min.css">
<!-- Utilise LESS -->

<link rel="stylesheet" href="stylesheets/ngprogress-lite.min.css">

</head>

<body ng-app="InTouch">
<!--<div ng-include="" src="'./partials/header.html'"></div>-->
<div ng-view>
</div>
</div>

<!-- <div id="footer">
  <div class="container">
    <div ng-include="" src="'./partials/footer.html'"></div>
  </div>
</div> -->

What is the method to divide this file into different ones ? Is it a problem to have such a long file ? Would'nt it have any problem of loading ?

Now the real question is, do you have a basic arithmetic jQuery plugin? — Shahar, Mar 01 '15 at 22:10

@felix, this is not a problem to have a long index file as you have presented. Consider the tag for instance ng-include, you may want to uncomment and use this as a resource.

<!--<div ng-include="" src="'./partials/header.html'"></div>-->

This will fetch html asynchronously after initial load. https://docs.angularjs.org/api/ng/directive/ngInclude

Now consider your app.js, it will register as many modules that your project is using. These modules will be loaded asynchronously. So it is not such a terrible thing having as many script tags listed as you do.

<script type="text/javascript" src="app.js"></script>

When you build this for production, I would recommend minifying and concatenating your scripts however, that will reduce the number of requests to the server.

The AngularJS Yeoman project has examples on how to do that. https://github.com/yeoman/generator-angular

It can be a problem as the project grows though. For example my Chromium tabs straight up freeze if I'm trying to open my app if it's not minified. It's an annoying issue and I have no idea how to fix it. — Nephilim, Mar 11 '22 at 10:19

For development, what you have is fine. However when you deploy to production, you will want to combine all of the JavaScript files into one so that you have a single script. This SO question: Combine and Minify Multiple CSS / JS Files gives some good suggestions on how to do this. The most upvoted tool is minify.

Here are some reasons why combining the files would be a good idea:

It's faster. One single download is more efficient than many small downloads. (See this question: Is it better to load many small JavaScript files or one large JavaScript file?)
SEO. Many search engine spiders only index up to a certain number of bytes. You will want to make your head as succinct as possible in order to allow the engine to get to the real content.

Warning: It can get too big, and your Chrome tabs will freeze when you try to develop locally. — Nephilim, Mar 11 '22 at 10:20
