How to use mLab..!

Step 1) Set up a mLab Account. 

           To get started with mLab u need to create a mLab account and login to that account. Then you can add as many database subscriptions as you want.

 

Step 2) Create a database Subscription.

           After you have created your account add a new database subscription. Get started quickly at no cost with a free sandbox database. 

Step 3) Connecting to your new database

 In a terminal window, connect to your database using the mongo shell.

 example :- % mongo ds012345.mlab.com:56789/dbname -u dbuser -p dbpassword

You can grab your connection info after logging into your account and navigating to the database homepage

Here is a one example to how mLab connected to nodejs application.

Step 4) Load Data to the database.

Here’s a quick exercise that tests an insertion into your new database:

1. Assuming you successfully connected using the mongo shell in the previous step, run the following command:

    > db.person.insert({ "Name" : "Damith" })
   

2. Next, run the command in the first line below and confirm that the shell output matches the second line (your “_id” value will be different):

    > db.person.find()
    { "_id" : ObjectId("526705b4a3559a176784b4af"), "Name" : "Damith" }
