connect is not a function when connecting to mongodb

Question

Error occurs when trying to run the function from the mongodb website that connects code to db.

const MongoClient = require('mongodb')

const client = new MongoClient(uri, { useNewUrlParser: true });
client.connect(err => {
  const collection = client.db("test").collection("devices");
  // perform actions on the collection object
  client.close();
});

Error is:

client.connect(err => {
  ^

    TypeError: client.connect is not a function

I have mongodb installed via npm and uri defined as the string they gave. Do I need anything else?

Answer 1

The reason is that you should import the MongoClient class:

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

Instead of the following line in your code: const MongoClient = require("mongodb");
