Setting Up MongoDB Atlas and Performing CRUD Operations Using MongoDB Compass

Creating an Account on dev.to

I initially created an account on dev.to and logged in.

Installing MongoDB Compass on Linux

Next, I installed the latest version of MongoDB Compass for Linux as a .deb file via the terminal using the following commands:

wget https://downloads.mongodb.com/compass/mongodb-compass_1.43.3_amd64.deb
sudo apt install ./mongodb-compass_1.43.3_amd64.deb -y

Registering on MongoDB Atlas

After that, I created an account on MongoDB Atlas and signed in.

Creating a MongoDB Atlas Cluster

I created a free cluster on MongoDB Atlas.

After creating the cluster, I loaded the sample dataset.

Browsing Collections and Database Creation

I clicked "Browse Collections."

Then, I clicked Create Database and set the Database Name as 24SY040 and Collection Name as 24SY040.

Inserting Initial Document

After creating the database successfully, I inserted the following document:

• id:24SY040
• "Name": "Prasanth"

Creating a Database User

Next, I created a new user named temp_user with read and write permissions.

Configuring Network Access

Next, I went to the Network Access tab and added a new IP address by selecting the "Access from anywhere" option.

Connecting via MongoDB Compass

Then, I clicked the Connect option, selected Compass, and clicked Done.

Next, from MongoDB Compass, I pasted the connection URL with my username and password, then clicked Connect.

Performing CRUD Operations

In the MongoDB Compass, I spawned a shell and put the command "use 24SY040"

Create operation

db["24SY040"].insertOne({ name: "Aravind", roll_no: "24SY004" })

Read operation

db["24SY040"].find().pretty()

Update operation

db["24SY040"].updateOne(
  { name: "Aravind" },            
  { $set: { roll_no: "24SY040" }}
)

Delete operation

db["24SY040"].deleteOne({ name: "Aravind" })

Thank you!
