Push Notifications V2

[VNDRN]

I’m trying to implement push notifications by following the guide in the docs. I’ve encountered some issues/questions whilst doing.

In the section Upload Firebase Credentials under the dashboard section, this seems to be outdated? You can now access it via dashboard > Chat Messaging > Push Notifications instead of the description and images in the guide.

In the section Registering a device with Stream , it is unclear to me what the difference is between client.setLocalDevice and client.addDevice. I believe setLocalDevice was added for V2, but could someone explain the difference to me?

Thanks!

Prior to client.setLocalDevice, you would need to do two separate api calls:

await client.connectUser();
await client.addDevice();

But later we decided to make this more efficient, and merge these two api calls:

client.setLocalDevice(); // there is no api call here, we just store the device info in memory
await client.connectUser(); // pass the device info to backend

Ok, I get that, but why call client.addDevice after the user disconnects? It happens in the unsubscribeTokenRefreshListenerRef, which is called after client.disconnect?

And I could still use addDevice to add the device after the connection is already established?

Hey @VNDRN

it is not done after user disconnecting.. but rather after token refreshing (this is done by firebase)

messaging().onTokenRefresh(async newToken => {
        await Promise.all([
          removeOldToken(),
          client.addDevice(newToken, push_provider, USER_ID, push_provider_name),
          AsyncStorage.setItem('@current_push_token', newToken),
        ]);
      });
    };

This method will return a subscription removal method, and that is stored inside unsubscribeTokenRefreshListenerRef

What we do in this method is to remove the stale token from the server and send the new token

I hope its clear now
