问题 From my google search, we can send notifications to all users only from FCM console. Currently there is no support for that in REST API. But we can specify a topic in REST API and whoever subscribed to that topic will get the notification. Is there any restriction on user count on a single topic. What if 10k users subscribed to the topic and REST API choose that topic to send the notification. Will FCM send notification to all 10k users?

问题 Google Cloud Messaging (GCM) support two types of push messages: "notification" messages and "data" messages.

问题 I'm trying to switch the push message service. The new push service is Firebase. I have JSON with tokens from parse.com, but can't find how to import it in Firebase. 回答1: I'm pretty sure you can't just import the tokens used by parse.com to Firebase Cloud Messaging for use. What should be done is to register your client app users to FCM by adding it to your app. More details can be found in the Migrate your Parse Android App to Firebase (or if you're using iOS) docs: Suggested Migration

问题 I am testing out the Firebase Cloud Messaging function in my React app which was bootstrapped with create-react-app. Note that I have already intialized firebase (including admin SDK on server-side) properly and my client side is deployed on https. What I did so far was to: Initialize firebase messaging in firebase.js, and also request for notification permission and listen out for onMessage event const messaging = firebase.messaging(); messaging .requestPermission() .then(() => { console.log
