Exports HTML to javascript instructions. Create javascript functions from HTML templates.

npm i -D html2js-loader


Add the html2js-loader to your webpack.config.js.

  test: /\.html$/,
  use: {
    loader: 'html2js-loader',
    options: {}

Now, simply import/require any html. For example:

<!-- templates/list.html -->
<ul role="list">
    <li>Item one</li>
    <li>Item two</li>
    <li>Item three</li>
const createList = require('./templates/list.html');


this will be converted to the following javascript:

function createNode() {
  var e_0 = document.createElement("ul");
  e_0.setAttribute("role", "list");
  var e_1 = document.createElement("li");
  e_1.appendChild(document.createTextNode("Item one"));
  var e_2 = document.createElement("li");
  e_2.appendChild(document.createTextNode("Item two"));
  var e_3 = document.createElement("li");
  e_3.appendChild(document.createTextNode("Item three"));
  return e_0;

You can use this online tool: which will convert your html to javascript on the fly.

The loader will optimize this code by injecting the following base code into your bundle:

module.exports = {
    document_createDocumentFragment: () => {
        return document.createDocumentFragment();
    document_createElement: name => {
        return document.createElement(name);
    document_createTextNode: text => {
        return document.createTextNode(text);
    appendChild: (parent, child) => {
    setAttribute: (elem, key, value) => {
        elem.setAttribute(key, value);

This will enable the compiler to name mangle these function calls. For example if we convert the following html:

<ul role="list">
    <li>Item one</li>
    <li>Item two</li>
    <li>Item three</li>

That will produce the following minified base code (this will only be included once):

var a=function(e){return document.createElement(e)},b=function(e){return document.createTextNode(e)},c=function(e,f,g){return e.setAttribute(f,g)},d=function(e,f){return e.appendChild(f)}

And the following minified javascript instructions for the html template:

var e=a("ul");c(e,"role","list");var f=a("li");d(f,b("Item one"));d(e,f);f=a("li");d(f,b("Item two"));d(e,f);f=a("li");d(f,b("Item three"));d(e,f);
