Import html from typescript using webpack

Question

I am trying to import html into a variable in typescript using webpack.

Here is my setup:

package.json:

{
  "devDependencies": {
    "awesome-typescript-loader": "^3.2.3",
    "html-loader": "^0.5.1",
    "ts-loader": "^2.3.7",
    "typescript": "^2.5.3",
    "webpack": "^3.6.0"
  }
}

webpack.config.js:

const path = require('path');
const webpack = require('webpack');

module.exports = {
  context: path.join(__dirname),
  entry: './main',
  output: {
    path: path.join(__dirname, 'dist'),
    filename: 'app.js'
  },
  resolve: {
    // Add '.ts' and '.tsx' as resolvable extensions.
    extensions: [".ts", ".js"],
    modules: [
      "node_modules",
      path.join(__dirname, 'app'),
    ],
  },
  module: {
    rules: [
      {
        enforce: 'pre',
        test: /\.html$/,
        loader: 'html-loader',
      },
      // Faster alternative to ts-loader
      { 
        test: /\.tsx?$/, 
        loader: 'awesome-typescript-loader',
        options: {
          configFileName: 'tsconfig.json',
        },
        exclude: /(node_modules)/,
      },
    ],
  },  
};

main.ts:

import template from './template.html';
console.log(template);

template.html:

<p>Hello World !</p>

When I try to compile using webpack:

$ ./node_modules/.bin/webpack

I have been doing this for half a day, so you can be sure that template.htmlthis is where it should be.

From what I understand from the webpack configuration, the html loader must first process the file, so it must load the contents of the html file into a variable. At least it was used to work with es6 ...

Can anyone tell me how to load html into a variable using webpack / typescript? Or at least what's wrong with my approach.

- CommonJS "require" TypeScript :

const template = require('./template.html');

import, TypeScript . TypeScript 2.4.2.

( typings.d.ts):

// typings.d.ts
declare module '*.html' {
  const content: string;
  export default content;
}

html :

// main.ts
import template from './template.html';
console.log(template); // <p>Hello world !</p>

: (. ).

// webpack.config.js
config.module = {
  rules: [
    {
      test: /\.ts$/,
      loader: '@ngtools/webpack'
    },
    {
      test: /\.html$/,
      use: 'raw-loader'
    }
  ]
}
