What is the correct way to efficiently connect to MongoDB in parallel?

Question

MongoDB

const MongoClient = require("mongodb").MongoClient;   
const url = "mongodb://localhost:27017/";
const mongoClient = new MongoClient(url);
Here is an example, we have created a mono client, can we use the same client in parallel to connect to the database, or do we need to re-create it every time?
Well, or how to send many requests more efficiently without overloading node js.

Answer 1

Can. Moreover - you need a good reason to have more than 1 client in the application. the client keeps a pool of connections inside that is used for simultaneous requests, this pool can be customized to fit your needs
