CRUD Operations Using MEAN Stack
🛠️ CRUD Operations Using the MEAN Stack
The MEAN stack is a powerful combination of technologies used to build full-stack web applications. It includes MongoDB, Express.js, Angular, and Node.js. In this blog, we’ll look at how to perform CRUD operations using the MEAN stack.
🔄 What is CRUD?
CRUD stands for:
Create – Add new data
Read – Get data
Update – Change existing data
Delete – Remove data
These are the basic operations that almost every web app needs.
🧱 The MEAN Stack Components
MongoDB – A NoSQL database to store data in JSON-like format.
Express.js – A backend web framework for Node.js to handle routes and requests.
Angular – A frontend framework that handles user interactions and shows data.
Node.js – Runs JavaScript on the server and powers Express.
🛠️ How CRUD Works in MEAN
Let’s break down how each CRUD operation flows in a MEAN app:
1. Create
User fills out a form in Angular.
Angular sends a POST request to the Express backend.
Express takes the data and stores it in MongoDB.
2. Read
Angular sends a GET request to fetch data.
Express fetches the data from MongoDB.
The data is sent back and displayed in Angular.
3. Update
User edits data in Angular.
Angular sends a PUT request with updated info.
Express updates the record in MongoDB.
4. Delete
User clicks delete in Angular.
Angular sends a DELETE request.
Express removes the item from MongoDB.
✅ Final Thoughts
The MEAN stack is great for building modern, full-featured web apps. With it, you can handle everything — from saving data to displaying it — using JavaScript on both the frontend and backend. Learning how CRUD works in MEAN is a solid first step to becoming a full-stack developer!
