You have questions about Firebase, and the Firebase community has answers!
But do you know the best place to get your questions answered?
It can be kind of overwhelming to figure out which destination is the best for your particular question. What I'd like to explore today are your options, and how to choose the best one. Choosing the best (and knowing how best to ask) could give you a huge advantage in getting the answers you need. There are five leading options, each with a different purpose. Let's explore those options!
It might seems silly to say, but I think your question should start with a Google search. A well-constructed search could surface existing answers in some of the forums I'll discuss next. You can't pass up the chance of getting your question answered immediately because someone else asked it first!
Try entering your question directly into the search box. Or, if you have an error message in your code, try copying it in there. For exact error messages, sometimes it's helpful to put your search string in quotes to force the most relevant matches to the top of the results.
Bear in mind that not every search yields good results. In some cases, you might stumble across something so rare that only one other person has ever seen it!
That time I searched for "ERROR: Walrus not found: have you checked the polar ice caps?"
If a search doesn't give what you're looking for, it's time to choose from some other options.
But before we continue - if you end up deciding that your question is appropriate for multiple forums, be sure to state that you've cross-posted your question. That gives everyone a chance to figure out which forum may be the best options, and if the question has already been answered elsewhere. That saves everyone time.
Stack Overflow is great for programming questions. In fact, that's the only kind of question you're supposed to ask there. Many Firebase team members pay attention there, including members of the greater community. There are a few tips to making the best of your question on SO:
Not all questions are good for Stack Overflow. In particular, your question may be closed by the community if it's any of the following:
If your question is closed by the community, it will almost certainly not be answered. But don't worry: for questions about Firebase that don't follow the Stack Overflow requirements, there are other options!
Quora is great for general questions, especially those seeking recommendations and opinions. There doesn't have to be a "correct" answer to a question on Quora. It's OK to ask broad questions.
If you choose Quora, be sure to tag your question with the Firebase topic so it's more likely to get noticed by people who have experience with Firebase.
firebase-talk is a long-standing mailing list for people who are looking for open-ended discussion about all things Firebase. It's great for open-ended discussions that require a lot of text that goes back and forth between group members. Many Firebase team members scan the messages here.
When you post your first message here, be prepared to wait for some time for a moderator to accept it.
The Firebase Slack is where Firebase enthusiasts gather to talk about, well, Firebase! This is good for general chit-chat and gathering opinions. While some Firebase team members check in from time to time, it's not an official support channel. So if you have a question that better fits Stack Overflow or Quora, I think it's better to ask there first.
One notable exception is the Firebase Test Lab team who use the #test-lab channel for direct support.
Here's a couple tips for using the Firebase Slack effectively:
This is a good place to ask for urgent issues such as problems with your production app. It's also good for troubleshooting if you require some back and forth with a real person with a problem that can be reproduced in code. You can expect a response from support within 24 hours of asking your question.
Firebase support also handles bug reports and feature requests. So if you have one of those, please fill out the form in that link.
If you want a timely response, I would avoid the following destinations for general questions:
The other reason I would avoid these is because they have limited visibility to the world, whereas the destinations above are well known by the Firebase community. You probably want your question to reach the maximum number of people as possible, in order to get answered quickly.
However, we do encourage you to use Twitter and other social media to broadcast the questions you ask on other sites. For example, it's good to ask a question on Stack Overflow or Quora, then tweet the URL of the question with the hashtag #AskFirebase. Your questions may get picked up for use on the Firebase channel on YouTube.
The Firebase community loves to help with Firebase! And it's easier to get help if you follow the guidelines here to make sure your questions reach the correct audience.

I'm always amazed when I think about the fact that Firebase Cloud Messaging sends billions of messages a day. Developers on iOS, Android, and web rely on FCM to send notifications and data messages to their clients. We recently updated FCM to incorporate better security and new features, and now you can access the new FCM through the Firebase Admin SDK for Node.js, Python, Java, and Go.
The latest version of FCM, called FCM v1, includes the ability to send a single request with platform-specific overrides. For example, you can set a time to live for an Android notification and an APNs priority for an iOS notification in the same body. See the documentation or this blog post for more information on platform overrides.
You can now conveniently integrate your server-side applications with the FCM v1 API using the Firebase Admin SDKs. Here's how you can send a simple data message in Node.js:
var registrationToken = 'YOUR_REGISTRATION_TOKEN'; var message = { data: { score: '850', time: '2:45' }, token: registrationToken }; admin.messaging().send(message) .then((response) => { console.log('Successfully sent message:', response); }) .catch((error) => { console.log('Error sending message:', error); });
To see this code in Java, Python, and Go, check the documentation. To see all message payload options, check out the FCM v1 documentation. In addition to sending messages to devices and topics, the Admin SDK for FCM also allows you to manage topic subscriptions from your server.
Here's an example of subscribing to a topic in Node.js:
var registrationTokens = [ 'YOUR_REGISTRATION_TOKEN_1', // ... 'YOUR_REGISTRATION_TOKEN_n' ]; admin.messaging().subscribeToTopic(registrationTokens, topic) .then(function(response) { console.log('Successfully subscribed to topic:', response); }) .catch(function(error) { console.log('Error subscribing to topic:', error); });
To see this code in Java, Python, and Go, check the documentation. Thanks to the Admin SDK, it's even easier than ever to send messages! Check out the full documentation here. And if you build something cool with FCM, be sure to tell us about it! Tweet @Firebase and @ThatJenPerson and let us know how it's going!
