How to insert multiple items at once in a MongoDB collection

New Course Coming Soon:

Get Really Good at Git

I had the need to insert multiple items at once in a MongoDB collection, from a Node.js application

Here’s what I did:

const mongo = require('mongodb').MongoClient
const url = 'mongodb://localhost:27017'
let db, jobs

    useNewUrlParser: true,
    useUnifiedTopology: true,
  (err, client) => {
    if (err) {
    db = client.db('myapp')
    jobs = db.collection('jobs')

    const data = [{...}, {...}]

Given an array of objects, I called insertMany() on the collection I wanted to populate.

Are you intimidated by Git? Can’t figure out merge vs rebase? Are you afraid of screwing up something any time you have to do something in Git? Do you rely on ChatGPT or random people’s answer on StackOverflow to fix your problems? Your coworkers are tired of explaining Git to you all the time? Git is something we all need to use, but few of us really master it. I created this course to improve your Git (and GitHub) knowledge at a radical level. A course that helps you feel less frustrated with Git. Launching Summer 2024. Join the waiting list!
