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
mongo.connect(
url,
{
useNewUrlParser: true,
useUnifiedTopology: true,
},
(err, client) => {
if (err) {
console.error(err)
return
}
db = client.db('myapp')
jobs = db.collection('jobs')
const data = [{...}, {...}]
jobs.insertMany(data)
}
)
Given an array of objects, I called insertMany() on the collection I wanted to populate.
