How to configure mongodb on node js with example

 

Try the below steps to configure mongodb on node js :

1. Install mongoose

npm install mongoose --save 2. Create a new Mongoose model var Model = require ( ' mongoose ' );

var User = new Model ();

User . name = ' John ' ;

User . age = 25 ;

3. Connect to the MongoDB server var mongoose = require ( ' mongoose ' );

var db = mongoose . connect ( ' localhost:27017/users ' );

// or use a connection string

var db = new mongoose.Db ( ' users ' , { host : ' localhost ' });

// or use a connection pool

var pool = new mongoose.DbPool ( 10 );

// or use a connection URI

var uri = "mongodb://localhost:27017/users " ;

db . connect (uri);

// or use a named instance

var instance = db . createConnection ( " mydb " );

instance . connect ();

// or use an existing database instance

var db = new mongoose.Db ( " users " , { host : " localhost " });

// or use a connection pool

var pool = new mongoose.DbPool ( 10 );

// or use a connection URI

var uri = "mongodb://localhost:27017/users " ;

db . connect (uri);

4. Create a model instance and query it var user = db . createModel ({ name : " John " , age : 25 });

user . save ();

console . log (user);

// {name: "John", age: 25}

Hope the above helps
