How to hash AngularJS template htmls with webpack

I recently made the transition from using gulp to webpack for our AngularJS application. While in the gulp version, I utilized the rev plugin to hash all files (css, js, and html), I am facing difficulty adding a hash to the html templates in webpack. This issue is causing problems as the browser keeps serving old html files. How can this be resolved? Below is my webpack configuration file:

const webpack = require('webpack');
const path = require('path');
const HtmlWebpackPlugin = require('html-webpack-plugin');
...

};

if (RemoteServer) {
     console.log('running with remote server', RemoteServer);
     config.devServer.proxy = {
    '/occm/*': 'http://' + RemoteServer
    };
 }

if (isProduction) {
config.plugins.push(
    new CleanWebpackPlugin(buildPath)
    );
}

module.exports = config;

One major advantage of utilizing Webpack is the ability to decrease the number of requests required for a browser to render your application, resulting in faster app initialization. This is accomplished by grouping related resources into "chunks", which are then loaded together in a single request. It's considered inefficient to load individual HTML templates separately without a specific reason.

A best practice approach involves consolidating all JS, HTML, and CSS code into a single large bundle that is loaded once. For larger applications, having a secondary 'vendor' bundle specifically for node_modules code can expedite development since this chunk tends to be more stable.

Another option:

In your scenario, if there isn't a specific need for keeping components separate (which you didn't mention), I would suggest combining HTML with the corresponding control code into a single chunk instead of loading HTML files individually.

An effective starting point would be to generate just two chunks. Update your optimization configuration with the following code:

optimization: {
  splitChunks: {
    cacheGroups: {
      commons: {
        test: /[\\/]node_modules[\\/]/,
        name: 'vendor',
        chunks: 'all'
      }
    }
  }
},

This setup will generate two chunks: a primary chunk containing all JS and HTML files, and a distinct one dedicated solely to content from the node_modules directory.

By doing this, you eliminate concerns about browser caching for HTML files as they are included in your primary chunk, leading to faster app startup times as an added benefit.

When I undertook a similar migration a few years ago, I approached it differently and did not require that particular type of solution. Instead, I focused on encapsulating each component as a module and then optimizing for lazy loading.

// Webpack Configuration
{
  test: /\.html$/,
  use: ['html-loader'],
},

Within each component, I simply included styles and templates like this:

require('./_proposal-page.scss');

(function() {
  'use strict';
  angular.module('component.myComponent', []).component('myComponent', {
    template: require('./proposal-page.html'),
    controller: MyController,
  });

  /** @ngInject */
  function MyController($log) {
    const $ctrl = this;
    $ctrl.$onInit = function() {
      $log.log('$onInit myComponent');
    }
  }
})();
if (typeof module !== 'undefined' && typeof exports !== 'undefined' && module.exports === exports) {
  module.exports = 'component.myComponent';
}

Webpack recognizes the requires and exports each .html file as a module, resulting in smooth functionality.
