Hi, talk about schedule notification with firestore, in my case, i want to give warning notification ex.5 minutes left, and when deadline coming i wanna change my data in firestore? is it possible? thank you

[@neilrara]

Is it possible to use callable functions with Firestore? Like changing the content of a Firestore document by directly calling a callable function? Docs provide a sample only for Realtime Database. I was wondering if the same can be done with Firestore (without using the Firestore triggers).

[@artemzhuravlenko9955]

Thanks for evеrythin. I spend all-day to saw that serious video. It was great!

[@FredYang]

The cleanUpReview can be deployed to more than two instances (two container), will that two instance handle the update at the same time? This could cost race condition or waste of processing, ist that right?

[@manish76345]

Sir, recently I used firebase authentication and hosting for my angular application they are simply awesome. I am also developed backend for that angular app using spring frame work. I wanna know how can use my backend rest api for my application

[@aytunch]

Hi Todd, Great video. I have a question: Why are always "triggers" shown when teaching about Cloud Functions? I always thought carrying all the client code related to Firebase and db logic to Cloud Functions would be very nice idea. It would keep the client code clean, make us not worry too much about safety rules. And we would be able to make updates without a client update if needed. That's why I am implementing my App to use http requests to Cloud Functions(custom cloud functions). But since it is never been promoted in your videos, I am a little skeptical. If I do that, would I have problems with Performance(cold start) or pricing? or something else? what are the pros/cons of carrying all Firestore crud and logic to Cloud Functions from client? Thank you very much

[@nerdswhosell]

Just to let you know... I have done exactly what you said. I created an API using Cloud Functions for an app of mine. I did it because I wanted to keep Firebase (except auth) out of my client bundle so it’s small. So I make http requests to do all of my database work and some other things too. I have not noticed any speed issues so far in production. It actually is surprisingly fast... even when I tested on bad connections and old phones.

[@aytunch]

@@nerdswhosell Thank you very much for the valuable input. I am relieved now:) what about pricing though? Do you think it is worse compared to using Firestore through the client directly? Edit: I am using Flutter

[@nerdswhosell]

Cool. I want to get deep into Flutter this year. But to your question... I don’t know. I mean you are adding another service into the mix so you will have to pay for the function invocations. But it depends on how big your app will be. I pay for the Flame plan and I think I get many millions of invocations which I don’t think my app will hit for a while. I am building a more robust version of my app which is a paid version and what I plan on doing for this one is only use functions for the small tasks like Todd gives examples of. For my API I am going to containerize it and use Cloud Run instead. I hope that helps in some way.

[@aytunch]

@@nerdswhosell Yes it helps a lot:) I wish you the best luck and success with your App. And I do think you will love Flutter even more once you get deep in to it. Right now I am struggling through deciding if I should move to Provider from Flutter_Bloc, or use them both or stay with Bloc. State management in my opinion is the part of Flutter which needs most interest by the community for it to become a leader in industry.

[@ahmdevelopments49]

guys i am having cold start issue. my cloud functions need 5-8+ seconds for booting up the first time a user calls them. the second time it goes faster(0.2sec) any idea on how to avoid this cold starts?

[@legend_mr_wayne]

Love the video, always good to know how things work, now I understand why cold start happens

hello sir, I am using the firebase function but when I call the function which is deployed in firebase I got [Error: UNAUTHENTICATED] back in the catch block.

How can I create a like system using Firestore. But Firestore allows one write per second per document? And is it good to use Firestore to store likes count and list of users who like because Firestore charges on Write and Read

[@Exploremore658]

So basically you need to learn typescript before being able to use cloud functions, right? How long would it take me to learn it in that case? Thanks

[@Exploremore658]

@@ToddKerpelmanCorp Thank you Todd. It's just that from now. I just know kotlin. So if I want to use cloud functions I will have to learn either type script or Javascript for creating advanced features in my app.

Can you quit Firebase, and get rid of Firebase, and just start an entire department for training and education - train on Oracle, Microsoft's services, Google services - you guys' videos and your documentation is decades better than anything else out there - literally love you guys and love the offering. Been using since 2013! I do have a quick question though - do you know or can reference a video on how to use Firebase in TypeScript? My googling skills have failed me. Can't seem to import firebase.

[@xerzes5900]

Have you found any thing yet?

[@DKPstudios]

XERZES from what I found you need a module framework (like Angular) to use it. If I figure out how to do it without, I’ll post here.

[@xerzes5900]

@@DKPstudios Thank you very much

[@Arystosedesss]

Ok so we have some quirks like functions can be called twice or with different ordering. Previously you removed flame plan, so any bigger mistake during development stage can kill our project and finance too (without any possibility to easy STOP it if there is big issue with for example infinite loops. No, alerts are not a solution..). Awesome.. depression and neurosis, we are waiting! :/

Hello Team Firebase! On the Cloud Firestore page of the Firebase Console, I don't see a way to start creating a Firestore database. The Create Database button has been replaced with the following text: "Ask a project owner to set up Cloud Firestore before using it for the first time"

Wait a sec, doesn't serverless computing means I don't pre-allocate the number of resources I need from the could so I don't have to worry about scaling and maintaining the server? Sure security and deployment speed are nice when running our code on the server-side, but I'm still using the exact resources I need when running the code on the client-side.
