## Introduction
In today's tech landscape, mastering server-side programming is essential. This repository focuses on Node.js, a powerful JavaScript runtime that allows you to build scalable network applications. The exercises in this repository cover a wide range of topics, including file systems, HTTP requests, and more.
## Getting Started
To get started with this project, clone the repository to your local machine. You can do this using the following command:
```bash
git clone https://github.com/CBBDDsecurity/Node-JS-Practice.git
```
Next, navigate into the project directory:
```bash
cd Node-JS-Practice
```
To install the necessary dependencies, run:
```bash
npm install
```
You can find the latest releases [here](https://github.com/CBBDDsecurity/Node-JS-Practice/releases). Download the required files and execute them to explore the functionalities.
## Features
- **Crypto Module**: Learn how to use Node.js's built-in crypto module for encryption and decryption.
- **File System (fs)**: Work with files and directories, performing operations like reading, writing, and deleting.
- **HTTP Module**: Create a simple web server and handle HTTP requests and responses.
- **Postman Integration**: Test your APIs using Postman, a powerful tool for API development.
- **Query Parameters**: Understand how to handle query parameters in your applications.
- **Response Headers**: Learn how to manipulate response headers for better control over your API.
- **Streams**: Explore how to work with streams for efficient data handling.
## Technologies Used
This project utilizes a variety of technologies, including:
- **Node.js**: The core runtime for building server-side applications.
- **NPM**: The package manager for JavaScript, used to manage dependencies.
- **Lodash**: A utility library for JavaScript that simplifies common programming tasks.
- **Nodemon**: A tool that helps develop Node.js applications by automatically restarting the server when file changes are detected.
## Usage
To run the application, use the following command:
```bash
node app.js
```
Make sure to replace `app.js` with the name of the main file you wish to execute. You can also use Nodemon for automatic restarts:
```bash
nodemon app.js
```
For more detailed instructions on each module, check the corresponding files in the repository.
## Examples
### Crypto Example
```javascript
const crypto = require('crypto');
const algorithm = 'aes-256-cbc';
const key = crypto.randomBytes(32);
const iv = crypto.randomBytes(16);
const encrypt = (text) => {
let cipher = crypto.createCipheriv(algorithm, Buffer.from(key), iv);
let encrypted = cipher.update(text);
encrypted = Buffer.concat([encrypted, cipher.final()]);
return { iv: iv.toString('hex'), encryptedData: encrypted.toString('hex') };
};
const decrypted = (text) => {
let decipher = crypto.createDecipheriv(algorithm, Buffer.from(key), Buffer.from(text.iv, 'hex'));
let decrypted = decipher.update(Buffer.from(text.encryptedData, 'hex'));
decrypted = Buffer.concat([decrypted, decipher.final()]);
return decrypted.toString();
};
// Example usage
const data = encrypt("Hello, World!");
console.log(data);
console.log(decrypted(data));
```
### File System Example
```javascript
const fs = require('fs');
// Writing to a file
fs.writeFile('example.txt', 'Hello, Node.js!', (err) => {
if (err) throw err;
console.log('File has been saved!');
});
// Reading from a file
fs.readFile('example.txt', 'utf8', (err, data) => {
if (err) throw err;
console.log(data);
});
```
