Conflict: Multiple assets emit to the same filename

I’m a webpack rookie who wants to learn all about it. I came across a conflict when running my webpack telling me:

ERROR in chunk html [entry] app.js Conflict: Multiple assets emit to the same filename app.js

What should I do to avoid the conflict?

This is my webpack.config.js:

module.exports = {
  context: __dirname + "/app",

  entry: {
    'javascript': "./js/app.js",
    'html': "./index.html",
  output: {
    path: __dirname + "/dist",
    filename: "app.js",
  resolve: {
    extensions: ['.js', '.jsx', '.json']
  module: {
    loaders: [
        test: /.jsx?$/,
        exclude: /node_modules/,
        loaders: ["babel-loader"]
        test: /.html$/,
        loader: "file-loader?name=[name].[ext]",



i’m not quite familiar with your approach so I’ll show you a common way to help you out.

First of all, on your output, you are specifying the filename to app.js which makes sense for me that the output will still be app.js. If you want to make it dynamic, then just use "filename": "[name].js".

The [name] part will make the filename dynamic for you. That’s the purpose of your entry as an object. Each key will be used as a name in replacement of the [name].js.

And second, you can use the html-webpack-plugin. You don’t need to include it as a test.
