How to install and use mongodb with node js?

Question

I am very new to MongoDB and node. So first of all:

How can I install MongoDB using the terminal on a Mac computer
Then how can I connect MongoDB with node?

How can I create a database in MongoDB using node?

Any help is appreciated. Thank You.

var MongoClient = require('mongodb').MongoClient;   
var url = "mongodb://localhost:8080/mydb";
MongoClient.connect(url, function(err, db){
if(err)
{
  console.log('error');
  throw err;
}
else
{
   console.log('success');
}
});

I tried this code but it shows an error.

This is the error I received:

You have to start mongo server in your computer and then only you will able to connect it to the client. — Oli

Default port for mongodb is 27017 so your url should be like mongodb://localhost:8080/mydb — Pavan Vora

You have to open the MongoDB server first.

Do this:

Go to the directory where mongo is installed: i.e.: <mongodb-install-directory>/bin
Start the server by : ./mongod --dbpath <mongo-data-directory>
