The React Router CLI comes from the @react-router/dev package. Make sure it is in your package.json devDependencies so it doesn't get deployed to your server.
To get a full list of available commands and flags, run:
npx @react-router/dev -h

react-router devRuns your app in development mode with HMR and Hot Data Revalidation (HDR), powered by Vite.
react-router dev
What is "Hot Data Revalidation"?
Like HMR, HDR is a way of hot updating your app without needing to refresh the page. That way you can keep your app state as your edits are applied in your app. HMR handles client-side code updates like when you change the components, markup, or styles in your app. Likewise, HDR handles server-side code updates.
That means any time you make a change to the current page (or any code that your current page depends on), React Router will re-fetch data from your loaders. That way your app is always up to date with the latest code changes, client-side or server-side.
| Flag | Description | Type | Default |

--clearScreen |
Allow/disable clear screen when logging | boolean |
|
--config, -c |
Use specified config file | string |
|
--cors |
Enable CORS | boolean |
|
--force |
Force the optimizer to ignore the cache and re-bundle |
