@nx/react

The React plugin contains executors and generators for managing React applications and libraries within an Nx workspace. It provides:

  • Integration with libraries such as Jest, Cypress, and Storybook.
  • Generators for applications, libraries, components, hooks, and more.
  • Library build support for publishing packages to npm or other registries.
  • Utilities for automatic workspace refactoring.

Setting Up React

To create a new workspace with React, run npx create-nx-workspace@latest --preset=react-standalone.

Keep Nx Package Versions In Sync

Make sure to install the @nx/react 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.

To add the React plugin to an existing workspace, run one of the following:

# For npm users

npm install -D @nx/react

# For yarn users

yarn add -D @nx/react

Nx 15 and lower use @nrwl/ instead of @nx/

Creating Applications and Libraries

You can add a new application with the following:

nx g @nx/react:app my-new-app

Nx 15 and lower use @nrwl/ instead of @nx/

To start the application in development mode, run nx serve my-new-app.

And add a new library as follows:

nx g @nx/react:lib my-new-lib

# If you want the library to be buildable or publishable to npm

nx g @nx/react:lib my-new-lib --bundler=vite

nx g @nx/react:lib my-new-lib --bundler=rollup

nx g @nx/react:lib my-new-lib \

--publishable \

--importPath=@myorg/my-new-lib

Nx 15 and lower use @nrwl/ instead of @nx/

Creating Components

Adding a component to an existing project can be done with:

nx g @nx/react:component my-new-component \

--project=my-new-app

# Note: If you want to export the component

# from the library use --export

nx g @nx/react:component my-new-component \

--project=my-new-lib \

--export

Nx 15 and lower use @nrwl/ instead of @nx/

Replace my-new-app and my-new-lib with the name of your projects.

Creating Hooks

If you want to add a new hook, run the following

nx g @nx/react:hook my-new-hook --project=my-new-lib

Nx 15 and lower use @nrwl/ instead of @nx/

Replace my-new-lib with the name of your project.

Using React

Testing Projects

You can run unit tests with:

nx test my-new-app

nx test my-new-lib

Replace my-new-app with the name or your project. This command works for both applications and libraries.

You can also run E2E tests for applications:

nx e2e my-new-app-e2e

Replace my-new-app-e2e with the name or your project with -e2e appended.

Building Projects

React applications can be build with:

nx build my-new-app

And if you generated a library with --bundler specified, then you can build a library as well:

nx build my-new-lib

The output is in the dist folder. You can customize the output folder by setting outputPath in the project's project.json file.

The application in dist is deployable, and you can try it out locally with:

npx http-server dist/apps/my-new-app

The library in dist is publishable to npm or a private registry.
