module.exports = {
  // your config values here
  plugins: [
    new HtmlWebpackPlugin({
        template: './index-template.ejs'
    }),
    // InlineChunkManifestHtmlWebpackPlugin defaults to:
    // { filename: 'manifest.json', manifestVariable: 'webpackManifest', chunkManifestVariable: 'webpackChunkManifest', dropAsset: false }
    new InlineChunkManifestHtmlWebpackPlugin()
  ]
};

Config

const inlineChunkManifestConfig = {
  filename: 'manifest.json', // manifest.json is default
  manifestVariable: 'webpackManifest', // webpackManifest is default
  chunkManifestVariable: 'webpackChunkManifest', // webpackChunkManifest is default; use in html-webpack-plugin template
  dropAsset: true, // false is default; use to skip output of the chunk manifest asset (removes manifest.json)
  manifestPlugins: [/* override default chunk manifest plugin(s) */],
  extractManifest: false // true is default. When set to false, manifestPlugins (incl default) is not applied
};
 
new InlineChunkManifestHtmlWebpackPlugin(inlineChunkManifestConfig)

Explicit inject

When option inject: false is passed to html-webpack-plugin the content of the chunk manifest can be inlined matching the config option chunkManifestVariable.

Example template for html-webpack-plugin:

<!DOCTYPE html>
<html>
  <head>
    <meta http-equiv="Content-type" content="text/html; charset=utf-8"/>
    <title><%= htmlWebpackPlugin.options.title %></title>
  </head>
  <body>
    <h1>My web site</h1>
    <%=htmlWebpackPlugin.files.webpackChunkManifest%>
  </body>
</html>

Override default chunk manifest plugin

To use plugins like webpack-manifest-plugin you can override the default plugin used to extract the webpack chunk manifest. To do this, you can do either of below configs:

inline-chunk-manifest-html-webpack-plugin apply dependency plugins:

const InlineChunkManifestHtmlWebpackPlugin = require('inline-chunk-manifest-html-webpack-plugin');
 
module.exports = {
  /* webpack config */
  plugins: [
    /* more plugins goes here */
 
    new InlineChunkManifestHtmlWebpackPlugin({
      manifestPlugins: [
        new WebpackManifestPlugin()
      ],
      manifestVariable: "manifest"
    }),
    new HtmlWebpackPlugin({
        template: './index-template.ejs'
    })
    /* more plugins goes here */
  ]
};

Plugins applied separately:

const InlineChunkManifestHtmlWebpackPlugin = require('inline-chunk-manifest-html-webpack-plugin');
 
module.exports = {
  /* webpack config */
  plugins: [
    /* more plugins goes here */
    new WebpackManifestPlugin(),
    new InlineChunkManifestHtmlWebpackPlugin({
      manifestVariable: "manifest",
      extractManifest: false
    }),
    new HtmlWebpackPlugin({
        template: './index-template.ejs'
    })
    /* more plugins goes here */
  ]
};
