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.
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
Creating Applications and Libraries
You can add a new application with the following:
❯
nx g @nx/react:app my-new-app
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

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
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
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.
