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":
let MongoClient = require('mongodb').MongoClient;
let url = "mongodb://localhost:27017/";
MongoClient.connect(url, function(err, db) {
if (err) throw err;
let dbo = db.db("mydb");
dbo.createCollection("customers", function(err, res) {
if (err) throw err;
console.log("Collection created!");
db.close();
});
});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.jsWhich 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.
