How to integrate an Angular 2 app into a Django app
<p>I've been following this <a href="https://angular.io/docs/ts/latest/tutorial/" rel="nofollow noreferrer">Tour of Heroes</a> tutorial. I have a Django app whose structure can be simplified as follows</p>

<pre><code>apps/my_app/migrations/
apps/my_app/__init__.py
apps/my_app/urls.py
apps/my_app/views.py

frontend_stuff/js/    javascripts here
frontend_stuff/css/   css here
</code></pre>

<p>the hero app has the following structure:</p>

<pre><code>heroes/app/           contains all the .ts and .html files
heroes/node_modules/  angular2 and other libraries
heroes/styles.css     css file
heroes/index.html
heroes/package.json and other config files
</code></pre>

<p>currently i've built an API using Django View that handles Http Request via URL and returns JSON. But where/how should I place this Angular app into the current Django app, and how can I load the Angular app into the browser upon the initial GET request to Django backend?</p>

<p>EDIT: more specific questions on loading HTML and JS:</p>

<p>Since Angular 2 uses <code>Component</code> and the templates are rendered by Angular rather than Django, how to let Angular "access" those html?  @Luis mentioned that those files should be placed inside the static folder, but <code>{% static %}</code> is Django syntax which wouldn't make sense to Angular.</p>

<p>Similarly, I suppose <code>app/main</code> (shown below) should also be placed in static folder. But how to refer to the location inside Angular? Thanks!</p>

<pre><code>  System.import('app/main')
        .then(null, console.error.bind(console));
</code></pre>

<p>UPDATE:
i followed <a href="https://stackoverflow.com/a/35815803/3974213">this answer</a> and used <code>/static/js/my_app/main</code> and it's "mostly" loading fine now. so far all my js files seem to be loaded; but the console log shows that some angular files give 404 error before loading successfully. error as shown below:</p>

<p>Update: the above error was due to incorrect path in System Confing. Now everything loads with the following config:</p>

<pre><code>&lt;script&gt;
  System.config({
    defaultJSExtensions: true,
    map:{
      angular2: '/static/js/node_modules/angular2',
      rxjs: '/static/js/node_modules/rxjs'
    },
    packages: {
      app: {
        format: 'register',
        defaultExtension: 'js'
      }
    }
  });
  System.import('/static/apps/my_app/app/main')
        .then(null, console.error.bind(console));
&lt;/script&gt;
</code></pre>
