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
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).
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?
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
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
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.
@@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
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.
@@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.
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?
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
@@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.
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"
im new using cloud functions in JAVA environment but recently my cloud function kill the process before the job is finishes, I know the support for java still in betha, but it would be nice if we have something like promise in javascrip, I hope see something like that in the future.
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.
This guy needs a raise and be in charge of all technical writing at Google. Absolutely excellent speaker and presenter
Definitely agree, never seen this good developer instructor

13:38 Top 5 Quirks
13:47 Quirk #1: Performance cold start
14:37 Quirk #2: Global variable out of sync on each server
15:21 Quirk #3: Global variables/libraries always loaded, slowing all cold starts
16:07 ...use lazy loading of libraries instead
16:17 Quirk #4: Order of function execution not guaranteed
16:57 Quirk #5: Duplicate events, use the unique eventID property which is the same across all duplicate function calls
17:52 Conclusion and next video topics
wow you are great
One of the coolest tutorial episodes I've ever watched! Keep going Todd, we love the way you bring us in the Firestore world!
I have been waiting for this series so badly
Ahhh I love this guy!!
He looks like the older version of Leonard Hofstadter from the Big Bang Theory
@@Bogdan-op2py exactly what I was thinking! Sounds like him too
@@Bogdan-op2py no, he's definitely Database Robin Williams
Jhus knw mn ..
when i saw him, i didn't even bother scrolling
This speaker is so good. I don't know what it is but i could listen to him talk about anything for hours
Man long time no see! Have been waiting you for long. Love your tutorials. Thank you
Anyone else notice the 'Club Data(bass)' 😂 incredible attention to detail!
When is the next video, did the series stop?? :(
And Todd Keplerpann you are awesome in explaining things man!
These videos are always fun to watch.
I want that Firebase shirt!!
I really enjoyed this series! Very clarifying and funny!!
Excellent video, well explained as ever :)
Good suggestion on Stripe / idempotency / eventID

like realtime database ?
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

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.

4:57 me_irl, so can i make Cloud Function using Dart?
@@ToddKerpelmanCorp too bad it's not natively supported :(
@@alvinvin00 I agree. Given Dart's foundation support for Flutter I can only hope that some Googlers are hard at work on this issue.
@firebase If functions could accidentally run twice, wouldn't that mess up any counters?
Why can't I give two or more likes :D If this would be a Medium, I would Clap my trackpad out :D Great presentation!

Pls elaborate, this would be my preferred approach too. Thanks.
wanted to learn more about infinite loops and now im stuck in one, why does this always happen to me??
I believe Cloud Functions as of February 2022 supports Python? Could you please confirm?
Urgent question, Can I connect firebase without node or react just from plain javascript page?
Yep, you can
