Mongo
Connect to a database and retrieve data from a collection
***

Here I have a collection of useful JS/TS snippets used in profession day to day work routine.

# Mongo

# Connect to a database and retrieve data from a collection

While crawling the official docs, could not find a working example of how to extract data from a database. The snippet below is basically a compilation of some posts from Stackoverflow:

#!/usr/bin/env node


const MongoClient = require('mongodb').MongoClient;


const MONGO_URI = 'mongodb://localhost:27017/?maxPoolSize=20&w=majority';
const client = new MongoClient(MONGO_URI);


async function run() {
  try {
    const connection = await client.connect();
    const database = connection.db('db_name');
    const registry = database.collection('collection_name');


    const result = await registry.find({}).toArray();


    console.log(result);
  } finally {
    await client.close();
  }
}
run().catch(console.dir);
