Sample MERN Stack Projects: Enhance Your Development Skills

The MERN stack is a powerful combination of technologies that allows developers to build robust, full-stack web applications. Whether you are a beginner or an experienced developer, working on MERN stack projects can significantly improve your programming skills and prepare you for a successful career in web development. In this guide, we will explore various project ideas, tools, and resources to help you master the MERN stack.

What is the MERN Stack?

The MERN stack consists of four key technologies:

• MongoDB: A NoSQL database for storing and managing data.
• Express.js: A web application framework for building server-side logic.
• React.js: A JavaScript library for building dynamic user interfaces.
• Node.js: A runtime environment for executing JavaScript on the server side.

These technologies together offer a comprehensive solution for building modern web development projects, covering both frontend and backend development.

Sample Code for a Simple MERN Application

Here is an example of a basic MERN stack application that displays a list of tasks:

Backend Code (Node.js)

📄
const express = require('express');
const mongoose = require('mongoose');
const cors = require('cors');

const app = express();
app.use(express.json());
app.use(cors());

mongoose.connect('mongodb://localhost:27017/mernstack', {
  useNewUrlParser: true,
  useUnifiedTopology: true,
});

const taskSchema = new mongoose.Schema({
  title: String,
  completed: Boolean,
});

const Task = mongoose.model('Task', taskSchema);

app.get('/tasks', async (req, res) => {
  const tasks = await Task.find();
  res.json(tasks);
});

app.post('/tasks', async (req, res) => {
  const newTask = new Task(req.body);
  await newTask.save();
  res.json(newTask);
});

app.listen(5000, () => console.log('Server running on port 5000'));

Frontend Code (React.js)

📄
import React, { useState, useEffect } from 'react';
import axios from 'axios';

function App() {
  const [tasks, setTasks] = useState([]);
  const [newTask, setNewTask] = useState('');

  useEffect(() => {
    axios.get('http://localhost:5000/tasks').then((response) => {
      setTasks(response.data);
    });
  }, []);

  const addTask = () => {
    axios.post('http://localhost:5000/tasks', { title: newTask, completed: false }).then((response) => {
      setTasks([...tasks, response.data]);
      setNewTask('');
    });
  };

  return (
    

      
Task List
      

        {tasks.map((task) => (
          
{task.title}
        ))}
      
       setNewTask(e.target.value)} 
      />
      Add Task
    
  );
}

export default App;
