Usage

You can also pass configuration optionsRemix Icon to rootAuthLoader() no matter which method you use.

Without a callback

To configure Clerk in your Remix app, you must export the rootAuthLoader() function as the root loader() function.

app/root.tsx
// Your other imports

// Import `rootAuthLoader`
import { rootAuthLoader } from '@clerk/remix/ssr.server'

// Export `rootAuthLoader()` as the root route `loader`
export const loader: LoaderFunction = (args) => rootAuthLoader(args)

// The rest of your code

With a callback

If you need to load in additional data, you can pass a callback to rootAuthLoader() that handles the route data loading with auth state.

app/root.tsx
// Your imports

export const loader: LoaderFunction = (args) => {
  return rootAuthLoader(args, ({ req }) => {
    const { sessionId, userId, getToken } = req.auth
    // Add logic to fetch data
    return { yourData: 'here' }
  })
}

// The rest of your code

Pass configuration options

To pass configuration optionsRemix Icon to rootAuthLoader(), you can pass an optional argument to the rootAuthLoader() function.

app/root.tsx
// Your imports

export const loader: LoaderFunction = (args) => {
  return rootAuthLoader(
    args,
    ({ req }) => {
      const { sessionId, userId, getToken } = req.auth
      // Add logic to fetch data
      return { yourData: 'here' }
    },
    {

    },
  )
}

// The rest of your code
