Over the years, I have developed various software applications and hired developers for projects ranging from small startups to enterprise-level solutions.
A crucial part of my job has been deciding which technology stack to choose for each specific project, and why. The choice of stack impacts everything, from development speed to long-term scalability and maintenance.
In this two-part article, I’m sharing my experience with some of the most popular technology stacks, along with real-world examples and code snippets to help you understand where each shines.
Let’s dive into the top five technology stacks, detailing their components, when to use them, and how they can help you achieve your project goals.
1. MEAN Stack
- Technologies: MongoDB, Express.js, Angular, Node.js
- Best for: Dynamic web applications with highly interactive user interfaces.
When I first started working with the MEAN stack, what drew me in was the fact that you can use JavaScript from the backend to the frontend, making it incredibly efficient. MongoDB, a NoSQL database, is flexible with JSON-like documents, and Angular provides a structured way to manage complex user interfaces. Express.js simplifies backend development, while Node.js powers the server side.
Sample Code:
Node.js and Express.js (Backend)
const express = require('express');
const app = express();
const MongoClient = require('mongodb').MongoClient;
app.get('/', (req, res) => {
res.send('Hello from MEAN Stack!');
});
MongoClient.connect('mongodb://localhost:27017/mydatabase', (err, db) => {
if (err) throw err;
console.log('Database connected!');
});
app.listen(3000, () => {
console.log('Server running on port 3000');
});
Angular (Frontend)
import { Component } from '@angular/core';
@Component({
selector: 'app-root',
template: `<h1>Hello from Angular in MEAN Stack!</h1>`,
})
export class AppComponent {}
When to Use: Use MEAN when developing real-time, dynamic web applications, such as messaging apps, social networks, or e-commerce websites that need to be scalable and highly interactive.
2. MERN Stack
- Technologies: MongoDB, Express.js, React, Node.js
- Best for: Web applications with a focus on dynamic and responsive user interfaces.
In some projects, I found that React’s component-based architecture was more flexible than Angular for frontend development, and that’s where the MERN stack comes in. With React replacing Angular, it allows for easier management of user interfaces and better performance optimization.
Sample Code:
Node.js and Express.js (Backend)
const express = require('express');
const app = express();
const mongoose = require('mongoose');
mongoose.connect('mongodb://localhost:27017/mydatabase', { useNewUrlParser: true });
app.get('/', (req, res) => {
res.send('Hello from MERN Stack!');
});
app.listen(3000, () => {
console.log('Server running on port 3000');
});
React (Frontend)
import React from 'react';
function App() {
return (
<div>
<h1>Hello from React in MERN Stack!</h1>
</div>
);
}
export default App;
When to Use: The MERN stack is best for applications where you need a rich, dynamic frontend with reusable UI components, such as social networks, content-sharing platforms, and SaaS products.
3. LAMP Stack
- Technologies: Linux, Apache, MySQL, PHP
- Best for: Traditional websites and dynamic web applications.
I’ve been using the LAMP stack since the early days of my LAMP! It’s reliable, widely supported, and great for applications where stability is key. Whether I’m building a content-driven website or a small-to-medium-sized web app, the LAMP stack has been a solid choice.
Sample Code:
PHP (Backend)
<?php
$servername = "localhost";
$username = "root";
$password = "";
$dbname = "mydatabase";
// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
echo "Hello from LAMP Stack!";
$conn->close();
?>
When to Use: LAMP is ideal for developing traditional dynamic websites, content management systems (CMS) like WordPress, and small-to-medium-sized web applications.
4. LEMP Stack
- Technologies: Linux, Nginx, MySQL, PHP
- Best for: High-performance websites that need to handle high traffic efficiently.
For performance-heavy applications, I often switch to the LEMP stack. The key difference is Nginx, which outperforms Apache in handling a large number of concurrent requests. It’s perfect when you’re expecting high traffic and need your application to stay responsive.
Sample Code:
Nginx Configuration
server {
listen 80;
server_name example.com;
root /var/www/html;
location / {
index index.php index.html;
}
location ~ \.php$ {
fastcgi_pass unix:/var/run/php/php7.4-fpm.sock;
include fastcgi_params;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
}
}
PHP (Backend)
<?php
$servername = "localhost";
$username = "root";
$password = "password";
$dbname = "mydatabase";
$conn = new mysqli($servername, $username, $password, $dbname);
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
echo "Hello from LEMP Stack!";
$conn->close();
?>
When to Use: LEMP is perfect for high-traffic websites, content-heavy applications, and media websites that need fast performance and scalability.
5. Django Stack
- Technologies: Django, PostgreSQL/MySQL, HTML/CSS/JavaScript
- Best for: Large-scale web applications with a focus on security, scalability, and speed.
Django is the stack I turn to when security and scalability are the top priorities. It’s Python-based, which makes it ideal for data-driven applications. With its built-in security features and rapid development capabilities, I’ve used Django for applications like social networks and secure enterprise solutions.
Sample Code:
Django (Backend)
# views.py
from django.http import HttpResponse
def home(request):
return HttpResponse("Hello from Django Stack!")
URL Configuration
# urls.py
from django.urls import path
from . import views
urlpatterns = [
path('', views.home),
]
When to Use: Django is best suited for large-scale applications, social networks, or enterprise-level systems where security and rapid development are critical.
