How to find unused package exports

In a monorepo

1. Add the check-exports script in the package.json of the package that needs to be checked

"scripts": {
  "check-exports": "pure-index"
}

2. Run

npm run check-exports

3. Depending on the project, you may need to configure Pure Index.

Tip

Use nx (or any other monorepo manager) to run a script for checking multiple packages with a single command.

Example

nx run-many --target=check-usage --parallel=12

In different repositories

1. Use the findUnusedExports function from JavaScript API.
