How to handle 'expired' Firebase Instance ID Token
AFAIK, the Firebase Instance Token will be refreshed under the following 4 conditions:
(i) App deletes Instance ID
(ii) App is restored on a new device
(iii) User uninstalls/reinstall the app
(iv) User clears app data
Suppose a user is using Token A as his 'FCM address'. Every time when he logs in the app, he will register the Token A to the Firestore along with this user's UUID so user-specific cloud message can be sent to him. When he logs out, the system will fire a request to firestore for removing the token A record.
Now, when the user reinstalls the app, the instance id is refreshed and a new Token B is generated. The Token A becomes useless. Unfortunately, if the user does not log out before the uninstallation, token A will stay in the firestore forever.
Any workaround or wiser way to handle this case?

Keeping your token registry up to date requires two steps:
- Remove outdated tokens from your application code.
- Check for outdated tokens and remove them when you send messages.
Your approach of removing a token that is no longer used, is #1.
The second step though is to remove tokens from your registry/database when you get a messaging/invalid-registration-token or messaging/registration-token-not-registered response when trying to send a message to it. The functions-samples repo contains a great example of this:
admin.messaging().sendToDevice(tokens, payload).then((response) => {
// For each message check if there was an error.
const tokensToRemove = ;
response.results.forEach((result, index) => {
const error = result.error;
if (error) {
console.error('Failure sending notification to', tokens[index], error);
// Cleanup the tokens who are not registered anymore.
if (error.code === 'messaging/invalid-registration-token' ||
error.code === 'messaging/registration-token-not-registered') {
// TODO: remove the token from your registry/database
}
}
});
});
The above code uses the Firebase Admin SDK for Node.js, but the same logic could also be applied to other platforms or when sending messages through the HTTPS endpoints.
