Basic Express.js Backend App

This simple backend application, built with Express.js, demonstrates how to set up a basic server, handle routes, and use middleware like CORS. The app fetches user data based on an ID, illustrating how to work with basic HTTP requests and responses.

Getting Started

Prerequisites

• Node.js installed on your machine. If you don't have it, you can download it here.
• Basic knowledge of JavaScript and familiarity with HTTP requests.

Installation

1. Clone the repository or download the source files.
2. Open your terminal and navigate to the project directory.
3. Install the dependencies:

   npm install express cors

Running the Server

1. Start the server by running:

   node index.js

2. The server will start on http://localhost:8000.

Endpoints

GET /:id

This route fetches user data based on the id parameter.

• Request:

  GET http://localhost:8000/1

  Replace 1 with any valid user ID (e.g., 2 or 3).

• Response: If the user is found, you'll get a JSON response like this:

  {
  	"user": {
  		"id": 1,
  		"name": "John Doe"
  	}
  }

  If the user is not found, you'll receive a 404 response:

  {
  	"message": "User not found"
  }
