If an insert fails when ordered is to true, the remaining inserts will not be executed. One optional setting to note for insertMany() is the boolean ordered. The only argument you are required to pass to insertMany() is an array of documents to insert.īoth insertOne() and insertMany() allow you to pass optional settings. To create multiple documents, use insertMany(). If the document does not include a field named _id, the MongoDB Node.js driver will add one automatically. insertOne() has only one required parameter: the document to insert. Use insertOne() to create a new document. These methods are known as CRUD (create, read, update, and delete) operations. The MongoDB Node.js driver provides a variety of methods to help you query your data. For more detailed information on how to get connected to a MongoDB database from a Node.js script, see Connect to a MongoDB Database Using Node.js. These are the basics of getting connected. Now you're ready to get connected: await nnect() const client = new MongoClient(yourConnectionURI) For more information on how to find your connection URI and ensure your Atlas database is ready for connection, see the official MongoDB documentation on connecting to a cluster. Then create an instance of MongoClient by passing your connection URI to it. Import the MongoClient in a new Node.js script: const = require('mongodb') You can use the MongoClient to connect to a MongoDB database. Now that you have completed the prerequisites, you're ready to begin coding! Get Connected Add the MongoDB Node.js Driver to your Node project dependencies using the following command:.The easiest way to get started with MongoDB is to create a free cluster in MongoDB Atlas, MongoDB's fully-managed, multi-cloud document database service. If you haven't already, install Node.js and create a new Node.js project.Prerequisitesīefore you begin, you'll need to ensure you've completed a few prerequisite steps. In this section, we'll walk through how to set up a Node.js script that connects to a MongoDB database.
