"Error: Angular component's template URL could not be located by Webpack when in production

I have a TypeScript component for an Angular 1.5 app using webpack as the build tool. The component code is as follows:

import {Component} from "../../common/decorators"

const app = angular.module('app');
 @Component(app, {
  selector: 'navComponent',
  controllerAs: 'ctrl',
  styleUrls: './nav.style.scss',
  templateUrl: './nav.template.html'
 })
 class navComponent {
 static $inject = ['$scope', '$attrs', '$element'];

 constructor(private $element, $scope: ng.IScope, $attrs) { 

 }   
}

And this is the decorator used:

export const Component = function(module: ng.IModule, options: {
  selector:string,
  controllerAs?: string,
  styleUrls?: string,
  template?: string,
  templateUrl?: string
}) {
  return (controller: Function) => {
   module.component(options.selector, angular.extend(options, {   controller: controller }));
 }
}

Everything works fine locally, but after building with webpack, it fails to work in production with the bundled JavaScript file.

This is the loader configuration being used:

loaders: [
        {
            test: /\.html$/,
            loader: 'html-loader',
        }

Here's the error message encountered:

Error: [$compile:tpload] Failed to load template: /components/nav/nav.template.html (HTTP status: 404 Not Found)

Answer №1

One helpful tip is to include your template directly:

...
template: require('./nav.template.html')
...

If you prefer to use a separate template file, consider using CopyWebpackPlugin. Keep in mind that this may result in additional requests for each file when deploying your application.

Answer №2

If you are utilizing the es6 module import, you can easily import your HTML using the following style of import statement:

import mainTemplate from './mainpage.component.html';

Afterwards, you can reference this template in your component as shown below:

export class mainPageComponent implements ng.IComponentOptions {
  public bindings: any;
  public controller: any;
  public template: string;
  public controllerAs: string;

  constructor() {
    this.bindings = {};
    this.template = mainTemplate,
    this.controllerAs = "vm";
    this.controller = mainPageController;
  }
}

By following these steps, your template will be loaded properly. To ensure smooth handling during the webpack build process (webpack 3 utilized here), you can utilize html-loader.

{
    test: /\.html$/,
    exclude: /node_modules/,
    use: { loader: "html-loader" }
  }

This approach should work effectively for you.
