Error Message: “GET /blog/about HTTP/1.1” 404 Not Found: Troubleshooting Guide for Blog App Creators

If you’re creating a blog app and encountering the frustrating “GET /blog/about HTTP/1.1” 404 Not Found error message, you’re not alone! This pesky error can bring your development progress to a grinding halt. But fear not, dear developer, for we’ve got a comprehensive guide to help you troubleshoot and resolve this issue once and for all.

What’s Causing the Error?

Before we dive into the solutions, let’s understand what’s causing this error message. When a user requests a URL, the server responds with a status code. In this case, the 404 Not Found error code indicates that the server cannot find the requested resource (/blog/about). This can occur due to a variety of reasons, including:

• Incorrect routing or URL mapping
• Misconfigured server settings
• Missing or incorrect file/folder structure
• Typo in the URL or file name
• Incompatible or outdated dependencies

Solution 1: Check Your Routing and URL Mapping

Take a closer look at your routing configuration. Make sure you have correctly defined the routes for your blog app. Check for any typos or incorrect syntax in your route definitions. Here’s an example of a basic route configuration:

app.get('/blog/about', (req, res) => {
  res.render('about');
});

In this example, the `/blog/about` route is defined to render the `about` template. Ensure that you have created a corresponding template file (e.g., `about.ejs` or `about.html`) in the correct directory.

Using a Route Debugger

To troubleshoot routing issues, consider using a route debugger like `morgan` or `express-debug`. These tools can help you visualize and analyze your route configurations, making it easier to identify any mistakes.

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

const app = express();

app.use(morgan('dev'));

// Define your routes...

Solution 2: Verify Server Settings and Configuration

Double-check your server settings and configuration files. Ensure that your server is properly configured to serve static files and render templates correctly.

Check Your Server Configuration File

In your server configuration file (e.g., `server.js` or `app.js`), verify that you have correctly set up your server to serve static files and render templates. Here’s an example:

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

app.use(express.static('public'));
app.set('views', './views');
app.set('view engine', 'ejs');

In this example, the server is configured to serve static files from the `public` directory and render templates using the `ejs` engine.

Verify File and Folder Structure

Ensure that your file and folder structure is correct. If you’re using a template engine like EJS, make sure your template files are in the correct directory and have the correct file extension (e.g., `about.ejs`).

File/Folder	Location
about.ejs	/views/about.ejs
public	/public (static files)
server.js	/server.js (server configuration)

Solution 3: Check for Typos and Incompatible Dependencies

Typos can be sneaky and difficult to spot. Double-check your code for any typos in file names, folder names, and URL paths.

Additionally, ensure that you’re using compatible dependencies and versions. Outdated or incompatible dependencies can cause issues like the “GET /blog/about HTTP/1.1” 404 Not Found error.

Update Your Dependencies

Run `npm outdated` or `yarn outdated` to check for outdated dependencies. Update your dependencies to the latest versions using `npm update` or `yarn upgrade`.

Conclusion

Troubleshooting the “GET /blog/about HTTP/1.1” 404 Not Found error can be a challenge, but by following this comprehensive guide, you should be able to identify and resolve the issue. Remember to:

1. Check your routing and URL mapping
2. Verify your server settings and configuration
3. Check for typos and incompatible dependencies

By following these steps, you’ll be back to building your blog app in no time. Happy coding!
