Node & MongoDB - Embedded Document
To insert embedded document(s) in a collection of a database, you can use collection.insertOne() or collection.insertMany() methods to insert one or multiple documents.
database.collection("sampleCollection").insertOne(firstDocument, function(error, res) { if (error) throw error; console.log("1 document inserted"); }); database.collection("sampleCollection").insertMany(documents, function(error, res) { if (error) throw error; console.log("Documents inserted: " + res.insertedCount); });
Example
Try the following example to insert documents in a mongodb collection −
Copy and paste the following example as mongodb_example.js −
const MongoClient = require('mongodb').MongoClient; // Prepare URL const url = "mongodb://localhost:27017/"; const firstPost = { title : 'MongoDB Overview', description : 'MongoDB is no SQL database', by: 'tutorials point', url: 'http://www.tutorialspoint.com', comments: [{ user: 'user1', message: 'My First Comment', dateCreated: '20/2/2020', like: 0 }, { user: 'user2', message: 'My Second Comment', dateCreated: '20/2/2020', like: 0 }] }; // make a connection to the database MongoClient.connect(url, function(error, client) { if (error) throw error; console.log("Connected!"); // Connect to the database const database = client.db('posts'); database.collection("samplePost").insertOne(firstPost, function(error, res) { if (error) throw error; console.log("1 document inserted"); }); // close the connection client.close(); });
Output
Execute the mysql_example.js script using node and verify the output.
