I'm new to the whole cloud functions thing , I have two questions , first is the timeout for the function is really just 60 second ? and why is that , and second how can I deploy the cloud function always ? will it charge more ? can anyone explain this to me ? I have write the post in typescript but should I deploy it every 60s its not a solution ! what should I do ? I'm working on flutter app .
should I deploy the function using the cloud-function package ? I'm so confused !
I have two questions , first is the timeout for the function is really just 60 second ?
Yes.
and why is that
A reason is not given anywhere in the documentation. However, it's a sensible place to start for the sort of work that's expected to be performed in Cloud Functions. It's definitely not intended for long-running work.
how can I deploy the cloud function always ? will it charge more ? can anyone explain this to me ?
I think you are confused about what a timeout is. It's not the amount of time that a function stays deployed. Once deployed, it still stay deployed forever. The timeout refers to the amount of time it will spend processing a single event before shutting down that one invocation.

Today after a simple deploy for adjusts (without install new features) my angularfire application stay lot delay. When checked the console log see this message, in login screen, without any operation or request.
Somebody can give some trick?

Problem solved after unistall old unused functions

I am also facing the same error in angularfire 2. It looks like there are two possible options to solve this issue
1) User firebase cloud functions. Move your code there and call the function from angular. Retrieve the data.
2) Write a python script and execute it using tools like PyCharm.
I got stuck when edit example function generateThumbnail, which is convert to multiple image resolution but unfortunately, it raised some exceptions then it running continuously util system report quota exceeded. Would you show me how to stop running process in Functions?
The simplest way to stop a function like that is to deploy an empty function for it instead, or to deploy an index.js without the function present.
I am making a spam counter ( on Firebase ). What I do is I use database trigger on firebase cloud functions to increment a path (/counter/${uid}). This path will hold an integer for each user that other path will have a security rule that reference to it and check whether it exceed the limit. However, I would like to clear the counter once a day.
When I search on google I found official way of firebase to do this by using another Google cloud service to deploy cron job. However, I wonder if I use setInterval on cloud function instead would work. This task would only be a one line execution ( admin.database().ref('/counter').set({}) . And it is not so serious that if it were to skip once or twice of the execution due to some problem, it should be ok.
Thanks
The use of setInterval won't work, and it's not really ever recommended to do so. You can use setInterval to keep a function alive for some amount of time, but you will be paying for that time even if the function is just waiting. Also you are still subject to the way Cloud Functions will time out your function (default 60 seconds, max 9 minutes by special configuration).
Don't use setInterval as you'll be paying for un-used compute time.
Instead see this video on YouTube; https://www.youtube.com/watch?v=CbE2PzvAMxA
They go into detail of how to setup a free-schedule service and setup a HTTP trigger that should achieve the result you're after.
Is there a way to disable a Cloud Function for Firebase through the Firebase dashboard?
I deployed a Cloud Function with a bug which caused an infinite loop of the function being triggered, updating the data, then the function triggering again. I discovered the error quickly, but I had to fix the code and redeploy the entire project to get the function to stop triggering.
Even though I deployed the new function, the deployment took some time and the function was triggered hundreds of times (which actually caused others to be triggered hundreds of times).
I'd like to be able to disable a function immediately when this happens, but I don't see any options in the dashboard or through the Firebase CLI.
If you view Cloud Functions in the Cloud Console, you can delete them individually from there: https://console.cloud.google.com/functions
Dont want to delete the function as I want to keep the usage history, logs, health ect?
This work around,long winded, but does the trick:
Disable function:
comment out the code in then function in your index.js
deploy just the firebase function:
firebase deploy --only functions:functionName
Enable function:
uncomment code
redeploy just the function with above line
Unfortunately Firebase has only a delete option and no disable option :(
A thing that I'm doing which isn't particularly neat but does the job. is just add a node in the database. for me I have a weekly script I run where I don't want my cloud functions to run when that's running. so at the top of my function I read that node and if the script is running, I just return early. not ideal but saves me having to comment out and redeploy every time
For me the fastest way is to edit function code directly in Google Cloud Console editor. In case of the HTTP function adding something like this at the beginning of a handler
res.status(500).send('The function is disabled');
return;
I use a solution similar to Red Baron. I have a Firestore Collection of booleans (one for each function) and I check that boolean at the beginning of my function to determine if it's allowed to run. The function will indeed be called, but it won't do anything if that boolean is set to false. It's not a perfect solution because it doesn't completely disable the function. But at least it will retain the log history.
Is it possible on Firebase or Parse to set up something kinda like a cron job?
Is there a way to set up some sort of timed operation that runs over the stored user data?
For example, I'm writing a program that allows people to RSVP for lunch everyday. If you have RSVPed by noon, then you get paired up with somebody else who has also RSVPed. Using JavaScript, the user can submit their RSVP in the browser.
The question is, can Firebase/Parse execute the code to match everyone at 12:00pm every day?
Yes, this can be done with Parse. You'll need to write your matching function as a background job in cloud code, and then you'll need to schedule the task in the dashboard. In terms of the flexibility in scheduling, it's not as flexible as cron but you can definitely run a task at the same time every day, or every x minutes/hours.
Tasks can take 15 mins max to execute before they're killed, so depending on the size of your database or the complexity of your task, you may need to break it up into different tasks or make it resumable.
Just to confirm about Firebase:
As #rickerbh said, it can be done with Parse, but currently there is no way for you to run your code on Firebase's server. There are 2 options for you 2 solve this:
You could use Firebase Queue and run your code in Node.js
You could use a different library such as Microsoft Azure (I still haven't tried this yet, I'm not sure if it provides Job Scheduling for Android)
However, Firebase is working on something called Firebase Trigger, which will solve our problem, however it is still not released with no confirmed release date.
