Getting started with Cloud Functions

Cloud Functions allows you to write server code that responds to events. You can respond to HTTP requests and events from within the Firebase ecosystem.
This lets you respond to events in services like Firestore, Authentication, Storage, Realtime Database, and so many other Firebase services.
Chapters:
0:00 - Serverless concurrency, eventings, and scale
1:35 - Setting up the Firebase CLI to boilerplate functions
2:20 - Setting up a project
4:35 - Project structure
5:30 - The anatomy of a function
7:24 - https events: handling requests and responses
9:23 - Running the local emulator suite
10:38 - Setting up breakpoint debugging in functions
12:23 - Deploying Cloud Functions
13:28 - Firestore triggers
15:08 - Best practice: promises & background triggers
15:46 - Running the Firestore local emulator & function shell
18:25 - Before building! Make sure to check out Extensions.

I've been using functions for a long time and learned so much during this video... Wish this had come out when I started w/ Firebase 🙂 More like this please

[@LearningwithJS-ei3ci]

I agree these videos make it easier to learn .

[@AtuOma]

wow.. welcome back David East

[@Ryan-zz6hh]

shoutout to cloud function hellworld all seriousness though, great tutorial.

[@arunsharma0001]

Eagerly waiting from complete video on cloud functions and express.js, also will be much appreciated if you could include the best practices and optimization. Thanks

[@user-yc3mr7tg7z]

same lul

[@cindysi63]

Fantastic video. Easy to follow and nicely explained. Thankyou. Very cool tech.

[@shintasari9667]

😅😅 , . 😊😊😊

[@anmolsharma9539]

Just a quick tip: If you want to use firestore your emulator port must be same as the function emulator port. In my case I was using the firebase-admin-sdk and the function port was 5000 & firestore emulator at 5001, so instead of the local emulator it directly push the data in the production firestore.

[@srivats22]

Amazing video... Really well explained

[@mfk8475]

We need an updated firebase cloud functions tutorial, the others were from 5 years ago.

[@antoineweb1]

Never knew about the function shell feature.

[@codewithfelix3940]

great video, when is cloud functions going to support java

[@JuanLopez-zh2sp]

Help, run test with onDocumentCreated for the 2gen in the emulator and it generates errors, how can I identify what the error is?

[@chaminduchanaka641]

How to pass parameters (Key value pairs) for test functions?

[@antoineweb1]

excellent!!

[@jbwesleyster]

its great !!

[@Vijayking505]

Nice

[@antoineweb1]

function name has to be lowercase? but the sample code provided by firebase is "helloWorld", aka not lowercase

[@davejl79]

I was loving Python functions until they stopped working. I have a simple on_call function that just stops responding after an hour, then I have to re-deploy. All it does it calls an external API to fetch a small amount of data then retrieves a small amount of docs from Firestore. Maybe move to JS? p.s. Please change the shocking font in this demo. 😆

[@CharlesAE]

Can you guys switch to dark backgrounds please?

[@applesheep6117]

hello mr firebase this is an epic video i wll like an subscrib !!

[@Bozkurt-1071]

👏👏👏

[@Coccolinoification]

wish I had found this video long time ago :(

[@Vijayking505]

🌟🌟🌟🌟🌟 Nice

[@boots172]

Who make the decision to use only lowercase? Who puts dashes in function names? It makes for a completely crazy migration path for v1 to v2. Essentially a rewrite.

[@antoineweb1]

13:27 Gen 1 and Gen 2 are mixed up I believe

[@evangelosspyromilios5994]

Functions with Python ?

[@danvilela]

"needs java" 💀

[@jefforycarretta996]

Ah dude im the newest ill grab coffee

[@bid0u12345]

I don't understand why you're using typescript. If you know typescript, you know JavaScript, but if you know JavaScript, you don't necessarily know typescript. So why not using JavaScript so this tutorial reaches a wider audience?

[@paca3107]

TypeScript its just a JS linter, which adds only fake types. If you ignore this part its pure JavaScript, so even if you dont know TS, you know what its going on.
