Chapter 2: MongoDB Getting Started
MongoDB Getting Started
Just like “MongoDB Home” was mostly the welcome/intro page in tutorials, “MongoDB Getting Started” is the next logical section — it’s the practical “first steps” guide that almost every tutorial, documentation, or course has.
In simple words:
MongoDB Getting Started = The beginner-friendly section that teaches you:
- How to set up MongoDB for the first time (cloud or local)
- How to connect to it
- How to run your very first commands (create database, insert data, query something simple)
- Usually includes the hello-world equivalent: “insert one document → find it → yay!”
It’s not a single fixed thing — different places call their version slightly differently, but the goal is always the same: get you from zero to “I have a working MongoDB database” in the shortest time possible.
Where do you usually see “MongoDB Getting Started”?
| Place | What they name it / link style | What it actually teaches (2026 style) |
|---|---|---|
| Official MongoDB Docs | “Get Started” or “Getting Started with MongoDB” | Create Atlas cluster → connect → CRUD basics |
| MongoDB Atlas section | “Get Started with Atlas” | Free cloud cluster in 5–10 minutes |
| W3Schools | “MongoDB Getting Started” | Install mongosh → basic shell commands |
| MongoDB University (free courses) | “Introduction to MongoDB” or “Getting Started with Atlas” | Video + hands-on labs |
| YouTube / Blogs | “MongoDB Getting Started in 10 Minutes” / “Crash Course” | Quick setup + first queries |
The official most recommended one in 2026 is:
- https://www.mongodb.com/docs/get-started (focuses on Atlas + app connection)
- Or the quick interactive one: https://www.mongodb.com/docs/manual/tutorial/getting-started (5-minute in-browser tutorial with Atlas)
Let’s Do It Like a Real Teacher — Step-by-Step “Getting Started” Class (Recommended 2026 Path)
Goal today: In next 15–20 minutes, you have a real MongoDB database running in the cloud (free forever), and you insert + query your first data.
Step 1: Create Free MongoDB Atlas Account (Cloud — Easiest & Most Popular)
- Open browser → go to https://www.mongodb.com → click “Try Free” (big button usually top right)
- Sign up with Google / GitHub / Email (takes 30 seconds)
- After login → you’ll land on Atlas dashboard
- Click “Build a Database” or “Create” (free tier M0)
- Choose Shared → M0 Free → pick any cloud provider (AWS is fine) → any region close to India (Mumbai is great for low latency)
- Give cluster name (e.g., “FirstCluster”) → click Create Cluster (takes 1–3 minutes)
While it’s building…
Step 2: Set Up Security (Important — Don’t Skip)
Once cluster is ready:
- Click “Database Access” (left menu) → Add New Database User
- Username: e.g., “student”
- Password: generate strong one (save it!)
- Role: Atlas admin (for learning)
- Click Add User
- Click “Network Access” → Add IP Address
- For learning: choose “Add My Current IP Address” (or 0.0.0.0/0 if you’re switching networks — but less secure)
Step 3: Get Your Connection String
- Go back to Clusters / Database Deployments
- Click Connect button on your cluster
- Choose mongosh (shell) or Drivers (for code later)
- Copy the connection string — it looks like:
|
0 1 2 3 4 5 6 |
mongodb+srv://student:<password>@firstcluster.abcde.mongodb.net/?retryWrites=true&w=majority |
Replace <password> with your real password.
Step 4: Install mongosh (MongoDB Shell) — Your Command Line Friend
- Windows/Mac/Linux → download from: https://www.mongodb.com/try/download/shell
- Or use npm if you have Node.js: npm install -g mongosh
Check version:
|
0 1 2 3 4 5 6 7 |
mongosh --version # Should show something like 2.x.x in 2026 |
Step 5: Connect & Say Hello (The Real “Getting Started” Moment!)
Open terminal / command prompt → run:
|
0 1 2 3 4 5 6 |
mongosh "mongodb+srv://student:YOUR_PASSWORD@firstcluster.abcde.mongodb.net/" |
(Replace with your string)
If successful → you’ll see:
|
0 1 2 3 4 5 6 7 8 9 |
Current Mongosh Log ID: ... Connecting to: mongodb+srv://... Using MongoDB: 8.0.x Using Mongosh: 2.x.x |
Now type these one by one (press Enter after each):
|
0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 |
// Switch to a playground database (MongoDB creates it automatically) use myFirstDatabase // Insert your first document — like adding a student record db.friends.insertOne({ name: "Rahul from Hyderabad", age: 24, city: "Hyderabad", learning: "MongoDB Getting Started", mood: "Excited!" }) // See what you just added db.friends.find().pretty() // Add more friends db.friends.insertMany([ { name: "Priya", age: 22, hobby: "Coffee" }, { name: "Amit", age: 25, city: "Secunderabad" } ]) // Find everyone db.friends.find().pretty() // Find only Hyderabad people db.friends.find({ city: "Hyderabad" }).pretty() |
You should see output like:
|
0 1 2 3 4 5 6 7 8 9 10 11 12 13 |
{ _id: ObjectId('...'), name: 'Rahul from Hyderabad', age: 24, city: 'Hyderabad', learning: 'MongoDB Getting Started', mood: 'Excited!' } |
Congratulations 🎉 — you just completed MongoDB Getting Started officially!
Bonus: Load Sample Data (Atlas Makes It Super Easy)
Back in Atlas dashboard:
- Click your cluster → Load Sample Dataset button (top right-ish)
- Wait 2–5 minutes
- Now you have databases like sample_mflix with movies, comments, theaters…
Try this in mongosh:
|
0 1 2 3 4 5 6 7 |
use sample_mflix db.movies.find({ title: "RRR" }).pretty() |
See? Real movie data!
Summary Table – What “Getting Started” Usually Covers
| Step | What You Do | Tool / Place |
|---|---|---|
| Sign up & create DB | Free Atlas cluster | mongodb.com → Try Free |
| Security | User + IP whitelist | Atlas dashboard |
| Connect | Get SRV string | Connect button |
| Install shell | mongosh | Download page |
| First commands | use db → insertOne → find() | mongosh terminal |
| Optional | Load sample data, try Compass GUI | Atlas UI |
Understood everything?
Next class options:
- Want to connect this Atlas database to Node.js / Python / Java? (very common next step)
- Learn MongoDB Compass (nice GUI instead of terminal)
- First real mini-project (todo app / blog)?
- Or jump to queries with filters, sort, limit?
