Web Development Tutorial
Beginning Web Development
Web development involves the development of websites and web applications. This includes web design, web programming, and database management. In this tutorial we will walk you through the basics of web development — front-end and back-end.
1. Understanding the Basics
1.1 Front-End Development, What is it?
In web development, front-end development is the client side. It is all of the stuff that people actually see and use in their web browsers. Here are the main languages you will use for front-end development:
HTML (HyperText Markup Language)—The foundation of every webpage that provides structure to the content.
CSS (Cascading Style Sheets) : It is used for styling the HTML elements like layout, colors, and fonts.
JavaScript: A programming language that enables interactivity on web pages and the ability to update content dynamically, add animations, and more.
1.2 Back-end DeveloperWhat is a Back-end Developer?
Back-end development is the server-side of web development. The server, application and database interact with it. The key components include:
Server: A machine that holds the application and serves the contents to users.
Database − A system that used to store and manage data (e.g. MySQL, MongoDB etc)
Backend programming languages: such as PHP, Python, Ruby or Node. js that handle requests from the (client) side.
2. Your Development Environment Setup
Step 1: Setting Up Your Development Environment Before you start writing code, you need to prepare an environment that is suitable for it.
2.1 Code Editor
Select a code editor that fits your work style. Popular options include:
Visual Studio Code: Versatile editor with many extensions
Sublime Text: A fast and lightweight editor.
Atom: A free editor with a highly customizable workspace.
2.2 Local Server
To get things started from the back-end, how to run a local server. Some common tools are:
XAMPP – A very simple Apache distribution, provides MySQL, PHP, and Perl.
MAMP: This is like the same thing, but for macOS.
Node. js: For server-side Javascript.
3. Front-End Development
3.1 HTML Structure
Step 1: Set Up Basic HTML: Begin with a Basic HTML Document:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>My Web Page</title>
</head>
<body>
<header>
<h1>Hi there, This is My Site</h1>
</header>
<main>
<p>This is a simple web page. </p>
</main>
<footer>
<p>© 2024 My Website</p>
</footer>
</body>
</html>
3.2 Styling with CSS
Now you have some CSS here to apply styles to your page. Create a file named styles. css:
body {
The fonts used for the gastropods and rocks graphics.
margin: 0;
padding: 0;
background-color: #f4f4f4;
}
header {
background: #35424a;
color: white;
padding: 10px 0;
text-align: center;
}
main {
padding: 20px;
}
footer {
text-align: center;
padding: 10px 0;
background: #35424a;
color: white;
}
Step 1 — Link the CSS file in your HTML:
Text-compatible version for Browser: Text version compatible with web browser: <link rel="stylesheet" href="styles. css">
3.3 JavaScript for Adding Interactivity
Writing JavaScript in your HTML file:
<script>
document. document.addEventListener("DOMContentLoaded", function() {
const message = document. createElement('p');
message. This is how I set the text content during that event listener.;
document. body. appendChild(message);
});
</script>
4. Back-End Development
4.1 Simple Server with Node. js
Set up a basic server with Node. js:
1. Install Node. js from the official website.
2. Create a new folder for your project and go to that folder using the terminal.
mkdir my-website
cd my-website
npm init -y
npm install express
3. Create a file named server. js:
require('express)
const app = express();
const PORT = process. env. PORT || 3000;
app.get('/', (req, res) => {
res. send('Hello, World!' );
});
app.listen(PORT, () => {
console. consolelog`Server running on http://localhost:${PORT}`;
});
4. Start the server:
node server.js
Open your web browser and go to http://localhost:3000 and see your server work.
4.2 Working with a Database
It allows you to be able to read and write to a database. For instance, using MongoDB along with Node. js:
1. Ensure that you have MongoDB installed with the service running.
2. Step 3: Interact with db using mongoose
npm install mongoose
3. Establish connection in your server to mongo DB. js:
mongoose — Mongoose for your MongoDB database.
mongoose. connect('mongodb://localhost/mydatabase', {useNewUrlParser: true, useUnifiedTopology: true});
4. Define a schema and model:
Here is an example user schema: const userSchema = new mongoose. Schema({
name: String,
age: Number,
});
const User = mongoose. model('User', userSchema);
5. Deploying Your Website
Once you have designed your website, you will need to deploy it on the web.
5.1 Select a Hosting Provider
Select a hosting provider. Popular options include:
DotCloud/Heroku: Very beginner and Node. js.
Netlify — Best for Static Sites
Vercel – made for React and Next js applications.
5.2 Deploying Your App
Even a more basic guide to your hosting provider on how to deploy your application. For Heroku, you would:
1. Create a Heroku account.
2. Install the Heroku CLI.
3. Git initYour codeGit addDeployed with:
git add.
The command is: git commit -m "Deploying my website"
heroku create
git push heroku master
Conclusion
The area of web development is massive and requires a creative as well as technical skillset. The piece aimed to give you a basic initial knowledge about front-end and back-end development. While your journey continues to the journey of frame
works like React, Angular, or Vue for the front end or Express or Django for the back end.
Practice more, and you will soon be building functional, dynamic web applications!
