I'm trying to insert a document into MongoDB in Node.js. I have read from the DB successfully, and added documents via the command-line interface. However, I can't insert a document from JavaScript. If I do, I get an error: Error: Cannot use a writeConcern without a provided callback Here is my code: var mongodb = require("mongodb"); var MongoClient = mongodb.MongoClient; MongoClient.connect("mongodb://localhost:27017/test", function(err, db) { if (!err) { db.collection("test").insert({ str: "foobar" }); } }); I can't for the life of me figure out why I get this error. What did I do wrong, and how should I do this instead?
