Node.js MongoDB Create Collection
A collection in MongoDB is the same as a table in MySQL
Creating a Collection
To create a collection in MongoDB, use the createCollection() method:
Example
Create a collection called "customers":
var MongoClient = require('mongodb').MongoClient;
var url = "mongodb://localhost:27017/";
MongoClient.connect(url, function(err, db) {
if (err) throw err;
var dbo = db.db("mydb");
dbo.createCollection("customers",
function(err, res) {
if (err) throw err;
console.log("Collection created!");
db.close();
});
});
Run example »
Save the code above in a file called "demo_mongodb_createcollection.js" and run the file:
Run "demo_mongodb_createcollection.js"
C:\Users\Your Name>node demo_mongodb_createcollection.js
Which will give you this result:
Collection created!
Important: In MongoDB, a collection is not created until it gets content!
MongoDB waits until you have inserted a document before it actually creates the collection.
