Nx with Rollup

The Nx Plugin for Rollup contains executors and generators that support building applications with Rollup across a Rollup monorepo.

Requirements

The @nx/rollup plugin supports the following package versions.

Package	Supported Versions
rollup	^3.0.0 || ^4.0.0

Nx generators install the latest supported versions automatically when scaffolding new projects.

Setting up @nx/rollup

Installation

Keep Nx Package Versions In Sync

Make sure to install the @nx/rollup version that matches the version of nx in your repository. If the version numbers get out of sync, you can encounter some difficult to debug errors. You can fix Nx version mismatches with this recipe.

In any Nx workspace, you can install @nx/rollup by running the following command:

nx add @nx/rollup

This will install the correct version of @nx/rollup.

Using @nx/rollup

Generate a new project using Rollup

You can generate a new library that uses Rollup with the following command:

nx g @nx/js:lib mylib --bundler=rollup

This will create a new library configured to use Rollup for building.

Set up CI for your Rollup monorepo

In CI, Nx runs nx affected to rebuild and retest only the projects a change touches, and caches results to skip repeated work.

For a complete pipeline, see Set up CI.
