## React Router with Nx
React Router is the successor of Remix and is the recommended routing library for new projects that may require Server-Side Routing (SSR).
There are three modes when using React Router: `framework`, `declarative` and `data`. `Framework` mode is the most comprehensive and is what will be covered in this recipe.
We'll show you how to create a [React Router](https://reactrouter.com/home) application with Nx.
## Create Nx Workspace
```{% command="npx create-nx-workspace@latest acme --preset=apps" path="~/" %}
✔ Which stack do you want to use? · react
✔ What framework would you like to use? · none
✔ Application name · acme
✔ Would you like to use React Router for server-side rendering [https://reactrouter.com/]? · Yes
```
## Have an existing App?
If you already have an existing React Router application and want to add Nx to it you can do so by running the following command:
```shell
npx nx init
```
## Generate a React Router Application
If you would like to generate a new React Router application, you can do so by running the following command in your Nx workspace
```{% command="nx g @nx/react:app apps/happynrwl --routing --use-react-router" path="~/acme" %}
```
There is no need to install any additional plugins to use React Router with Nx. The `@nx/react` plugin already includes support for React Router.
## Running the Application
Now that you have created your React Router application with Nx you can build, serve and test with the following commands:
### Build
To build your application run the following command:
```{% command="nx build happynrwl" path="~/acme" %}
> nx run acme:happynrwl
> react-router build

```
### Serve (Development)
To serve your application for development use the following command:
```{% command="nx dev happynrwl" path="~/acme" %}
> nx run happynrwl:dev
> react-router dev
1:30:42 p.m. [vite] (client) Re-optimizing dependencies because lockfile has changed
➜ Local: http://localhost:4200/
➜ press h + enter to show help
```
### Serve (Production)
To serve your application's production build use the following command:
```{% command="nx start happynrwl" path="~/acme" %}
> nx run happynrwl:build
> react-router build
vite v6.2.1 building for production...

```
{% callout type="note" title="PORT" %}
The default port for `production` is 3000 if you want to change it use the PORT environment variable
{% /callout %}
### Unit Test
To unit test the application run the following command:
```{% command="nx test happynrwl" path="~/acme" %}
> nx run happynrwl:test
> vitest
RUN v3.0.8 /private/tmp/projects/acme/apps/happynrwl
✓ tests/routes/_index.spec.tsx (1 test) 45ms
✓ renders loader data
Test Files 1 passed (1)
Tests 1 passed (1)
Start at 13:40:29
Duration 807ms (transform 59ms, setup 0ms, collect 168ms, tests 45ms, environment 372ms, prepare 52ms)
```
## Generate a Route
By default a route is generated for you when you create a new React Router application. If you would like to generate a new route you can do so by running the following command:
```{% command="nx g @nx/react:component --path=apps/happynrwl/app/routes/contact" path="~/happynrwl" %}
CREATE apps/happynrwl/app/routes/contact.tsx
CREATE apps/happynrwl/app/routes/contact.module.scss
CREATE apps/happynrwl/app/routes/contact.spec.tsx
```
Now we have create a new route called `contact` in our application. Let's add that route to our `routes.tsx` file.
```tsx
import { type RouteConfig, index, route } from "@react-router/dev/routes";
export default [
index('./app.tsx'),
route('about', './routes/about.tsx')
route('contact', './routes/contact.tsx')
] satisfies RouteConfig;
```
Now if we serve or app and navigate to `https://localhost:4200/contact` we will see our new route.
