# React Plugin
![React Logo](/shared/react-logo.png)
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:
```bash
# 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:
```bash
nx g @nrwl/react:app my-new-app
```
And add a new library as follows:
```bash
nx g @nrwl/react:lib my-new-lib
# If you want the library to be buildable and publishable to npm
nx g @nrwl/react:lib my-new-lib
```
### Creating Components
Adding a component to an existing project can be done with:
```bash
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
```bash
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:
```bash
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:
```bash
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:
```bash
nx build my-new-app
```
And if you generated a library with `--buildable`, then you can build a library as well:
```bash
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:
```bash
npx http-server dist/apps/my-new-app
```
The library in `dist` is publishable to npm or a private registry.

### Executors / Builders
React applications are built using the executors from the `@nrwl/web` plugin.
- [build](/web/build) - Builds a web components application
- [dev-server](/web/package) - Builds and serves a web application
- [package](/web/package) - Bundles artifacts for a buildable library that can be distributed as an NPM package.
### Generators
- [application](/react/application) - Create a React application
- [component](/react/component) - Create a React component
- [library](/react/library) - Create a React library
- [redux](/react/redux) - Generate a Redux slice for a project
- [storybook-configuration](/react/storybook-configuration) - Set up Storybook for a react library
