Entrypoint undefined = index.html using HtmlWebpackPlugin

entrypoint undefined = index.html angular
entrypoint undefined = extract-text-webpack-plugin-output-filename
html-loader
child html-webpack-plugin for index html
html-loader: 'html-webpack-plugin
htmlwebpackplugin react
htmlwebpackplugin multiple entry
htmlwebpackplugin is not defined

I'm using Webpack 4 and I'm creating the config file, when trying to use the HtmlWebpackPlugin it got this on the console: Entrypoint undefined = index.html, it opens the browser and the HTML does appear but I'm getting this weird message on the console, how to solve this?

That is how my config file looks like:

'use strict'

const webpack = require('webpack')
const { join, resolve } = require('path')

const HtmlWebpackPlugin = require('html-webpack-plugin')

module.exports = {
  mode: 'development', // dev
  devtool: 'cheap-module-eval-source-map', // dev
  entry: join(__dirname, 'src', 'index.js'),
  output: {
    filename: 'bundle.js',
    path: resolve(__dirname, 'dist')
  },
  module: {
    rules: [
      {
        test: /\.js$/,
        exclude: /node_modules/,
        loader: 'babel-loader'
      }
    ]
  },
  resolve: {
    extensions: ['*', '.js', '.jsx']
  },
  devServer: {
    contentBase: resolve(__dirname, 'build')
  },
  plugins: [
    new webpack.ProgressPlugin(),
    new HtmlWebpackPlugin({
      template: join(__dirname, 'public', 'index.html')
    }),

    new webpack.HotModuleReplacementPlugin(), // dev
    new webpack.NoEmitOnErrorsPlugin() // dev
  ]
}

Try this; you might be making wrong template path :

 new HtmlWebpackPlugin({
        template: resolve(__dirname, 'src/public', 'index.html'),
        filename: './index.html'
      }),

If public is in src folder this should work It's my assumption. Let me know if the issue still persists.

According to the creators of HtmlWebpackPlugin it's just a meaningless log message and an ignorable cosmetic issue. See this comment on the issue.

It seems like a problem with the extension of the template firing an unwanted loader. If the extension of the template is changed to any other the plugin will work.

If you're using the default webpack template system (EJS, as of webpack 4) it makes sense to use ejs because the template isn't valid html anymore:

new HtmlWebpackPlugin({
    // it works without 'path.resolve()'. No need for 'filename', defaults to 'index.html'
    template: "./public/index.ejs",
}),

webpack considers by default that the template is EJS and will automatically process it with the proper loader. If you use any other template system you will have to add the corresponding loader. More info on official documentation.

Entrypoint undefined = index.html using HtmlWebpackPlugin , This is a meaningless error in webpack 4, runing with an earlier version of webpack or ignoring the error with will fix this xahovuzu  Description When working with Webpack 4, people can now start with zero-configuration. This allows one to quickly get started with using Webpack, without any of the configuration hassle.

Entrypoint undefined = index.html using HtmlWebpackPlugin, This is a meaningless error in webpack 4, runing with an earlier version of webpack or ignoring the error with will fix this xahovuzu  You can't use a.css or.html file as an entrypoint (yet). It 'works' but will generate an 'empty' JS file with the webpack wrapper code. import the CSS in the JS entrypoint instead and the html-webpack-plugin emits the index.html (template) on it's own as an asset (no.html entry needed) and it won't pick it up anyways.

Getting Started, Before getting started, make sure you are using a recent version of Node. bytes [built] Child html-webpack-plugin for "index.html": 1 asset Entrypoint undefined  I think you should add the "entry" and "output" properties to your webpack config file. Your output should have a "path" pointing to a folder where the bundled files are stored.

The HtmlWebpackPlugin simplifies creation of HTML files to serve your webpack bundles. This is especially useful for webpack bundles that include a hash in the filename which changes every compilation.

  • show your directory structure where is your index.js? and where is your index.html ? This would be helpful in debugging the issue
  • The index.js is inside the src folder. The index.html is inside the public folder. There's nothing more than that. The Webpack config is in the root folder and the .babelrc with { "presets": ["env", "react"] }.
  • You got that wrong, the src is where the components are at, the public is where the static files are like the index.html. I noticed that this message appears only on the webpack-dev-server and not only for me but for a lot of people including the tutorials on Youtube, it seems to be harmeless and I could get rid of that by using stats: { children: false }
  • Glad to hear this. Finally it is fixed.
  • @xahovuzu how did you fix it? Please post an answer. Thanks!
  • @xahovuzu Did you ever resolve this? It's been bugging me forever and I can't find a fix anywhere.
  • @xahovuzu this does not only happen on web dev server, It happens for me when i run webpack --mode production
  • This didn't get rid of the undefined message for me.
