Webpack code splitting configuration example
module.exports = {
entry: {
main: './src/app.js',
output: {
// `filename` provides a template for naming your bundles (remember to use `[name]`)
filename: '[name].bundle.js',
// `chunkFilename` provides a template for naming code-split bundles (optional)
chunkFilename: '[name].bundle.js',
// `path` is the folder where Webpack will place your bundles
path: './dist',
// `publicPath` is where Webpack will load your bundles from (optional)
publicPath: 'dist/'

Hello Dan!

Do you have a reactjs example for code splitting with webpack 4 ?

I've tried so many things I've found online but I cannot get webpack to split my code.

If concerned about browser caching of bundles:

   filename: '[contenthash].bundle.js',
   chunkFilename: '[contenthash].bundle.js'

Thank you. my [name] is coming as 1, 0 ... as chunk name. I am using import(). can we have specific names for the chunk file names?

Great starting off point for code-splitting!

If I could make an addendum from trying what you used, the publicPath is what webpack in the browser will use. I was getting a confusing base path added at the beginning until I realized I had put a local path into publicPath based on what I interpreted from line 12 (instead of a browser relative path)
