Hey guys mongodb is one of my favourite databases but there arn't any orms that are actually type safe and impement db level schema rules so i made one please do give me feed back on it Thanks

AI puts this in every route file it touches:

    const client = new MongoClient(uri);
    await client.connect();
    // query
    await client.close();

Looks clean. Problem is a MongoClient is a POOL, up to 100 connections. A free Atlas cluster takes 500 total. Five of these alive at once and your whole cluster budget is gone before one query runs. Then everyone blames Mongo for "randomly dying under load".

One client for the whole app. Create it once, import it everywhere. The driver does the pooling, that is literally its job.

Bonus AI also never gets right: Next.js dev SSR mode re-runs module scope on every hot reload. Your correct singleton turns into a new pool every time you hit save. Cache it on globalThis and it survives reloads:

    let client = globalThis._mongoClient;
    if (!client) {
      client = new MongoClient(process.env.MONGODB_URI);
      globalThis._mongoClient = client;
    }

Costs nothing in production, saves your dev cluster.

Grep your codebase for "new MongoClient". If you have more than one, you have a problem.

Make a module you import, and reuse so every script imports the same active connection.

    // db.js
    import { MongoClient } from 'mongodb';

    export const client = new MongoClient(process.env.MONGODB_URI, {
      appName: 'my-api',
    });

    export const db = client.db('app');

How did my Node.js + MongoDB API take 13 seconds to respond? 😭

I recently ran into a performance issue in one of my backend APIs.

The API was built with Node.js + MongoDB, and the response time was nearly 13 seconds. 🫠

At first, I thought:

“Maybe MongoDB is slow?”

But obviously, there was more going on.

Now I'm trying to identify the actual bottleneck and optimize the API properly — database queries, indexing, population/aggregation, unnecessary processing, network calls, etc.

For developers who have worked on Node.js + MongoDB production APIs:

What would you check first when an API takes ~13 seconds to respond?

Would love to hear how you would debug this step-by-step

I am learning backend dev and have switched from using wsl2 to fedora. But having issues downloading MongoDB.
From all the gpt'ing I found out this :
Your Fedora kernel: 7.1.7

MongoDB 8.0.28: refuses to start

Error message: "6.19 and newer"

right now its recommending me to uninstall MongoDB completely and install it against but this time use Podman + MongoDB container(i don't have the slightest idea about what its talking about, im just a beginner for ffs!!😭)
So what should i do now??
can someone help me setup my Linux environment(focused on backend dev)
also recommend me some extensions/tools/apps that would make my life navigating fedora(GNOME DE) much easier!

P.S if possible can you dm me, i have some question regarding setting my up linux for backend dev🙏

I have a replica set cluster, and every 15 min there is 1.5GB data that is being dumped from oplog.

At the end I am trying for restores, withe the help of mongorestore tool with total of such 118 oplog dumps.

It takes around 10-15 min each for all the oplog dumps to be restored, in total of 9 hrs.

Is there any other way we can improve the perfomance

We are struggling with compliance requirements around the official MongoDB Agent container image. Our company policy mandates that all production images have zero Critical or High severity vulnerabilities.

Even across new version releases, we see the same fixable Critical/High CVEs lingering in the base image components. Because the image source isn't public, we can't patch and rebuild it ourselves without risking broken dependencies or vendor support issues.

What strategies are teams using to address this? Are people creating custom wrapper images, filing enterprise support requests, or using specific vulnerability suppression/exception workflows for third-party proprietary agents?

hello after searching for a stack that fit me well i found sveltekit remote function when adding mongo db with agregate framework from day one one of the simplest with best dx stack for someone just start learning and making apps pairing with atlas for fast deployment but when i read about mongo all i found is negative feedbacks and advices about avoid it at all cost for my side it s clicked more tryng to embeed as much as i can no schema just using zod for validation

is there here solo developers that made theirs own saas with mongo with active ? if yes how s your experience does aggregate framework enough for all you needs and not feeling the need to use an sql database ? thanks for the feedback
