Status Codes Case Studies

1. Introduction

HTTP status codes are essential for understanding the outcome of HTTP requests made to web servers. They are issued by a server in response to a client's request, providing information about the status of the request and the server's response.

2. Status Codes Overview

Status codes are divided into five categories:

• 1xx: Informational – Request received, continuing process
• 2xx: Success – The action was successfully received, understood, and accepted
• 3xx: Redirection – Further action needs to be taken to complete the request
• 4xx: Client Error – The request contains bad syntax or cannot be fulfilled
• 5xx: Server Error – The server failed to fulfill a valid request

3. Case Studies

const express = require('express');
const app = express();

app.get('/', (req, res) => {
    throw new Error('Something went wrong!');
});

app.use((err, req, res, next) => {
    res.status(500).send('Internal Server Error');
});

4. Best Practices

Here are some best practices when working with HTTP status codes:

• Use appropriate status codes to represent the outcome of requests.
• Provide meaningful responses for error codes, including troubleshooting steps.
• Log error responses for further analysis and debugging.
• Implement custom error handling to improve user experience.
