React Plugin

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.

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

# For npm users
npm install -D @nrwl/react

# For yarn users
yarn add -D @nrwl/react

Creating Applications and Libraries

You can add a new application with the following:

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

# If you want the library to be buildable or publishable to npm
nx g @nrwl/react:lib my-new-lib --buildable
nx g @nrwl/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 @nrwl/react:component my-new-component \
--project=my-new-app

# Note: If you want to export the component
# from the library use  --export
nx g @nrwl/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 @nrwl/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 --buildable, 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.
