How could I use a custom Backend like Supabase?

[Cherryrubim]

I've been reading the documentation for custom backend, but I'm still unclear on how I could extend or replace the logic for the DataSource, StorageSource, and AuthController interfaces.

I'll be grateful for any information or assistance provided. 🙏

Hi @Cherryrubim

It's very cool that you want to implement a backend like Supabase!
It is something we've had in our minds for a while.

For that reason, could you join our Discord channel so we can discuss the details?

In any case, as you said, you need to implement all the non-optional fields of those interfaces.

Internally we have implemented those components using React Hooks:

• Auth : https://github.com/Camberi/firecms/blob/main/lib/src/firebase_app/hooks/useFirebaseAuthController.ts
  This one is tied to our login view
  Essentially in charge of returning a logged in user.

• Datasource: https://github.com/Camberi/firecms/blob/main/lib/src/firebase_app/hooks/useFirestoreDataSource.ts
  For saving and retrieving data.

• Storage: https://github.com/Camberi/firecms/blob/main/lib/src/firebase_app/hooks/useFirebaseStorageSource.ts
  For uploading files.

Then you can use them in a custom app like in this example:
