When working with MongoDB you might have the need to remove all items from a collection.
You can do so by calling the deleteMany method of a collection, passing an empty object.
Like this:
yourcollection.deleteMany({})
Here’s a full example:
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('jobs')
jobs = db.collection('jobs')
jobs.deleteMany({})
}
)
