Troubleshooting

babel-loader is slow!

Some files in my nodemodules are not transpiled for IE 11

Babel is injecting helpers into each file and bloating my code!

NOTE: transform-runtime & custom polyfills (e.g. Promise library)

The Node.js API for `babel` has been moved to `babel-core`.

Exclude libraries that should not be transpiled

Top level function (IIFE) is still arrow (on Webpack 5)

Customize config based on webpack target

Customized Loader

Example

`customOptions(options: Object): { custom: Object, loader: Object }`

`config(cfg: PartialConfig): Object`

`result(result: Result): Result`
