Webpack 5
FYI, my understanding is that Webpack 5 does not automatically include this package by default, so this package's documentation may need to be updated 🙂
For those wanting to use this package with Webpack 5, here's a way to do so:
- Install the
utilandprocesspackages:
npm install util
npm install process
- In
webpack.config.js, add 'util' tofallbacksand make a globalprocessvariable viawebpack.ProvidePlugin:
module: {
...
},
resolve: {
...,
extensions: ['*', '.js', '.jsx'],
fallback: {
'util': require.resolve('util/')
}
},
plugins: {
...,
new webpack.ProvidePlugin({
// Make a global `process` variable that points to the `process` package,
// because the `util` package expects there to be a global variable named `process`.
// Thanks to https://stackoverflow.com/a/65018686/14239942
process: 'process/browser'
})
}
Updating the docs so webpack 5 users can reverse v5’s breakage sounds like a good idea.
Ya, that's what I'm thinking, too. Especially once Webpack 5 becomes the norm, although at the moment I think Webpack 4 is still far more popular 🙂
I'm usingwebpack.config.babel.js. And it says require is not defined. How can I make this work with es6?
@chardskarth likely you’d use import in a babelified webpack config, not require?

This is no longer the case. Verify if you need this module and configure a polyfill for it.
