manifest.json not injected

Hi,

my manifest.json is not injected in my html template

This is my plugins object:

const plugins = [
  new CopyPlugin([{ from: "./public" }]),
  new ExtractPlugin({
    filename: isProd ? "css/[chunkhash:7].min.css" : "css/[name].css",
    allChunks: true
  }),
  new HtmlPlugin({
    excludeChunks: ["polyfill"],
    inject: true,
    template: "./src/index.html",
    minify: { removeComments: isProd }
  }),
  new ManifestPlugin({
    filename: "manifest.json",
    name: "App",
    short_name: "App",
    description: "Description",
    fingerprints: false,
    orientation: "landscape"
  })
];

I had the same issue, I thought it was because of webpack-html-plugin v4 that I am using, so I wrote this PR, hope it might help you guys

I have the same problem, but you can easily solve by adding the tag to your template yourself:

<link rel="manifest" href="manifest.json">

However, in the end, I ended up using webapp-webpack-plugin
