npm:mongodb connection issue, timeout

It's resolved, mongodb documentation for nodejs was useful. Since importing MongoClient from deno package (https://deno.land/x/[email protected]/mod.ts) was giving frequent BSONError: corrupt object bson so migrated to npm:mongodb

import { MongoClient, ServerApiVersion } from "npm:[email protected]";
// import "https://deno.land/[email protected]/dotenv/load.ts"; // Load .env variables

const MONGO_USERNAME = Deno.env.get("MONGO_USERNAME");
const MONGO_PASSWORD = Deno.env.get("MONGO_PASSWORD");
const MONGO_APP_NAME = Deno.env.get("MONGO_APP_NAME");
const MONGO_CLUSTER_NAME = Deno.env.get("MONGO_CLUSTER_NAME");

const uri = `mongodb+srv://${MONGO_USERNAME}:${MONGO_PASSWORD}@${MONGO_CLUSTER_NAME}/?retryWrites=true&w=majority&appName=${MONGO_APP_NAME}`;


// Create a MongoClient with a MongoClientOptions object to set the Stable API version
const client = new MongoClient(uri, {
  serverApi: {
    version: ServerApiVersion.v1,
    strict: true,
    deprecationErrors: true,
  },
});

const connectToMongoDB = async () => {
  try {
    console.log("Connecting to MongoDB...");
    await client.connect();
    console.log("Successfully connected to MongoDB");
    return client.db("Faydo");
  } catch (err) {
    console.error("Error connecting to MongoDB:", err);
    throw err;
  }
};

const db = await connectToMongoDB();

export default db;

import { MongoClient, ServerApiVersion } from "npm:[email protected]";
// import "https://deno.land/[email protected]/dotenv/load.ts"; // Load .env variables

const MONGO_USERNAME = Deno.env.get("MONGO_USERNAME");
const MONGO_PASSWORD = Deno.env.get("MONGO_PASSWORD");
const MONGO_APP_NAME = Deno.env.get("MONGO_APP_NAME");
const MONGO_CLUSTER_NAME = Deno.env.get("MONGO_CLUSTER_NAME");

const uri = `mongodb+srv://${MONGO_USERNAME}:${MONGO_PASSWORD}@${MONGO_CLUSTER_NAME}/?retryWrites=true&w=majority&appName=${MONGO_APP_NAME}`;

});

const connectToMongoDB = async () => {
  try {
    console.log("Connecting to MongoDB...");
    await client.connect();
    console.log("Successfully connected to MongoDB");
    return client.db("Faydo");
  } catch (err) {

The serverApi object passed to MongoClient is important to connect mongodb using nodejs/deno.
