-Allow to use expressions in HTML syntax.
-You can use `interpolate` flag to enable interpolation syntax for ES6 template strings, like so:
-
-```js
-require('html-loader?interpolate!./file.html');
-```
-
-```html
-<img src="${require(`./images/gallery.png`).default}" />
-
-<div>${require('./components/gallery.html').default}</div>

-
-> ⚠ By default `file-loader` or `url-loader` use ES module syntax so you need use the `default` property.
-> You should not use the `default` property if you setup the `esModule` option to `false` value for `file-loader` or `url-loader`.
