functions-samples VS The gist

I tried to make a reddit like app. I used both realtime-database and firestore as database. The billing of the two is different from each other. I used realtime-database for frequently updated data (like or upvote, downvote count for ex.) and firestore for more stable and large data (post, comment, community and user data..). While doing this, I only used database rules, I did not use Cloud functions. So, I suggest you use a hybrid database to minimize your bill as much as possible and you can do amazing things with database rules. Have a good works.

const functions = require("firebase-functions"); // // Create and deploy your first functions // // https://firebase.google.com/docs/functions/get-started // // exports.helloWorld = functions.https.onRequest((request, response) => { // functions.logger.info("Hello logs!", {structuredData: true}); // response.send("Hello from Firebase!"); // });

Try something along these lines…? https://github.com/firebase/functions-samples/tree/main/Node-1st-gen/quickstarts/email-users

Cloud Functions for Firebase - Pros: Aligns to my app which uses Firebase; Cons: have to use Typescript which I have no experience with

Cloud Functions run on Google's servers and are part of your project, so only you and your project collaborators can deploy that code.

That would be a Firebase Cloud Function. Check their latest list of YouTube tutorials, they'll guide you through creating an app with full Firebase features.

Cloud Functions for Firebase

Cloud Functions are a serverless solution that allows you to run backend code in response to HTTPS requests or even more ⚡ powerfully, in response to events triggered by other Firebase products.

Graphile worker has been great for me because it's a library that works with Postgres that allows me to queue jobs and execute them on the server without adding too many additional layers of complexity for being able to accomplish async tasks. (I'm aware of how popular bull is, but I don't want to add another data-store only for async tasks)

Bull is currently in maintenance mode, we are only fixing bugs. For new features check BullMQ, a modern rewritten implementation in Typescript. You are still very welcome to use Bull if it suits your needs, which is a safe, battle-tested library.

I use bullmq with node

You might consider using a queue for processing the request. I've found bullMQ, which works with Redis, to be a nice developer experience.

BullMQ is a pretty solid choice: https://github.com/taskforcesh/bullmq It's the successor of Bull: https://github.com/OptimalBits/bull

BullMQ

For Node.JS you can use something like BullMQ (https://github.com/taskforcesh/bullmq) and then dispatch jobs to the message queue with your worker handling the jobs. You can read about an example for Bull MQ here (https://deadsimplechat.com/blog/best-nodejs-schedulers/#2-bull)

bullmq seems like an open issue

In order to try and mitigate the OOMs. I read the Background Jobs in Node.JS with Redis blog post and implemented Heroku Data For Redis with ioredis, BullMQ and Throng,
