When you're using Webpack, you have a really huge benefit that comes with all of your resolve statements being executed before your files are loaded into the browser. One thing that is insanely powerful is instead of using templateUrl, you can use template everywhere.
You don't need to worry about the templateCache or XHRs firing off to go get your templates. The way that this works is you simply require the file there. You're done. You do need to add a loader, but what's really nice about this is this makes things a lot more modular.
We could move these two files anywhere together. This component would still work. We wouldn't have to change the templateUrl to be pointing to the correct place wherever you move the file. This is a huge win that Webpack gives us.
If we were to save this and refresh, we're going to get an error right here. You need an appropriate loader to handle this file type. Webpack doesn't understand what on Earth this is talking about.
To accomplish this, we need a new loader. We'll npm install the raw loader. We'll add that as a dev dependency. We'll go to our Webpack config. We'll add a new loader here. Anything that ends in an HTML, we want it to use raw or the raw loader. Pro tip. This and this are the same thing. If you don't want it to be so verbose, then you just leave off the "loader."
Now, if we restart our dev server, everything should work properly. We refresh. Everything is good to go. You no longer need to use templateUrl or template anything. In fact, with something so simple as this, we don't even need to reference that. Because this application is using ES6, we could just as easily put our template right there. No worse for wear.
It depends on your style. Obviously, you're not going to want to do this if your template is very large, but as it is, it works really well just to use the template string with the backticks so we have multilines. That is loading your HTML, getting rid of your templateUrl, and just using template.
This really resolves a lot of the concerns with the HTTP backend when you're testing to make sure that you're loading stuff with ng-to-JS HTML loader plugins for Karma or whatever. You don't need to worry about that anymore with Webpack. That's another awesome thing that Webpack brings to the table with Angular.
