Answers:
Q: Where get a registration tokens?
The registration token is sent by the user when he uses your application. You need save token to use it later
Q: I need to remove all "bad" token from my database, how do I do that?
For example like this:
import { EventsList } from '@ioc:Adonis/Core/Event'
import FCM from '@ioc:Adonis/Addons/FCM'
import Device from 'App/Models/Device'
export default class NotificationListener {
public async created(notification: EventsList['notification::created']) {
const { title, text } = notification.toJSON();
const devices = await Device.all();
const registrationTokens = devices.toJSON().map(device => device.token);
const recipients = { registrationTokens };
const response = await FCM.send({ notification: { title, body: text }}, recipients);
const badTokens = registrationTokens.filter((token, i) => response[i].error !== null);
await Device.query().whereIn('token', badTokens).delete();
}
}
