MongoDB, the most popular NoSQL database, is an open-source document-oriented database. The term ‘NoSQL’ means ‘non-relational’. It means that MongoDB isn’t based on the table-like relational database structure but provides an altogether different mechanism for storage and retrieval of data. This format of storage is called BSON ( similar to JSON format).

MongoDB Module: This module of Node.js is used for connecting the MongoDB database as well as used for manipulating the collections and databases in MongoDB. The mongodb.connect() method is used for connecting the MongoDB database which is running on a particular server on your machine. (Refer to this article).

sort() Method of MongoDB is used for sorting the documents. This method is used to define the ordering of the documents.

  • Collection’s particular key  in ascending order
{Collection's key:1}

    const connect = db.db(databasename);
  
    // Connecting to collection
    const collection = connect.collection("aayush");
    console.log("Connection Created")
  
    // Sort the document key
    const sort = { rollno: 1 }
  
    collection.find().sort(sort).toArray((err, ans,) => {
        if (!err) {
  
            // Printing the documents
            console.log(ans);
