What is cache-bust-plugin?

cache-bust-plugin is a tiny Webpack plugin for generating bundle hashes. It's a useful alternative to html-webpack-plugin for when you only require cache-busting.

Installation

Install the cache-bust-plugin package from npm.
npm install cache-bust-plugin

Usage

import {CacheBustPlugin} from "cache-bust-plugin";

export const webpackConfig = {
    // ... Webpack config
    plugins: [
        new CacheBustPlugin({
            // ... cache-bust-plugin options
        })
    ]
}

If the writeToIndexHtml option is used then cache-bust-plugin searches for bundle file names in index.html (located in the root directory of your project) and appends bundle hashes using a query string.

index.html (before cache-bust-plugin) =>
<script type="text/javascript" src="/app.js"></script>
index.html (after cache-bust-plugin) =>
<script type="text/javascript" src="/app.js?hash=68b1a4d74cf4ef2b516f492bef010d8e"></script>

If the writeToJson option is used then cache-bust-plugin will write the bundle hashes to a JSON formatted text file.

{
  "app.css": "faa879842aef4070b5563ccdc0016cf8",
  "app.js": "faa879842aef4070b5563ccdc0016cf8",
