Use typescript to import an HTML template

My objective is to import my HTML template in a way that webpack can recognize and include them during the build process. (webpack -d)

As advised in this GitHub thread, I should follow these steps:

declare module '*.html' {
    const _: string;
    export default _;
}

Afterwards, importing the template using

import template from './myTemplate.html';
should be successful.

Unfortunately, it doesn't seem to work as expected.

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

Strangely enough, this approach seems to "work":

import * as template from './myTemplate.html';
console.log(template); // <p>Hello world!</p>

However, the following method fails:

$routeProvider.when("/test", {
    template: template, // ERROR! template is typeof(*.html) expected string
    controller: MyController,
    controllerAs: "$ctrl"
});

If I modify my *.html module to resemble this:

declare module '*.html' {
    const _: string;
    export = _; // changed this
}

I can then proceed with:

import * as template from './myTemplate.html';

$routeProvider.when("/test", {
    template: template, // Great success!
    controller: MyController,
    controllerAs: "$ctrl"
});

It does the job, but why doesn't

import template from './myTemplate.html';
behave as expected? What am I missing, since others on the GitHub thread seemed to have success with that method.

No need to worry, there is nothing wrong with what you are doing. When using

import template from './myTemplate.html';
, make sure to use the export default syntax.

Since webpack manages the import of html files, it does not automatically export default. You can check this out in the documentation here.

You have the option to customize your html-loader settings to utilize export default if needed.
