Web Development Guide

What Even is Web Development? 🤔

Web development is all about creating websites and web apps. It’s basically divided into three main parts:

  • 1️⃣ Frontend Development (What users see) – The design, buttons, text, images, and animations.
  • 2️⃣ Backend Development (What happens behind the scenes) – Databases, user logins, and server logic.
  • 3️⃣ Full-Stack Development (The best of both worlds) – If you know both frontend and backend, you’re full-stack! 😎

Step 1: Learn the Basics of Frontend Development 🎨

Frontend consists of three main technologies:

  • ✅ HTML – The skeleton of a website.
  • ✅ CSS – The styles, colors, and layouts.
  • ✅ JavaScript – Adds interactivity.

Example: Basic HTML Structure

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>My First Website</title>
</head>
<body>
    <h1>Welcome to My Website!</h1>
    <p>This is my first ever website. Cool, right?</p>
</body>
</html>

Step 2: Add Some Backend Magic 🧙‍♂️

The backend is responsible for handling user data and website functionality.

Popular backend languages:

  • ✔ Python (with Flask/Django)
  • ✔ Node.js (JavaScript)
  • ✔ PHP

Example: A Simple Backend with Flask (Python)

from flask import Flask
app = Flask(__name__)

@app.route('/')
def home():
    return "Hello, World! This is my backend."

if __name__ == '__main__':
    app.run(debug=True)

Step 3: Database (Where the Data Lives) 📂

Websites need a database to store information like user details, posts, and comments.

  • ✅ MySQL – Structured and widely used.
  • ✅ MongoDB – Great for flexible, fast data storage.
  • ✅ PostgreSQL – Powerful and secure.

Example: Connecting Python to MySQL

import mysql.connector

db = mysql.connector.connect(
    host="localhost",
    user="yourusername",
    password="yourpassword",
    database="yourdatabase"
)

cursor = db.cursor()
cursor.execute("SELECT * FROM users")
for user in cursor.fetchall():
    print(user)

Step 4: Hosting Your Website 🌎

Once your website is ready, you need to host it online. Some popular options:

  • 🌍 GitHub Pages – Free for static sites.
  • 🚀 Netlify – Great for frontend projects.
  • 🖥 Railway – Free hosting for backend apps.
