Resolving the 405 Method Not Allowed Error in Your Next.js Application

In the world of web development, errors can often be frustrating and challenging to resolve. One common issue that developers might face is the 405 Method Not Allowed error when making DELETE requests in a Next.js application. In this guide, we'll dive into the cause of this error and how you can fix it based on a real-world scenario.

The Problem

Imagine you're building a threads clone application using Next.js, and you have successfully implemented a like feature for users. However, upon clicking the like button to remove a like (which sends a DELETE request), you encounter the dreaded 405 Method Not Allowed error.

This can be particularly puzzling, especially if the POST requests for adding likes are working perfectly. Let’s explore why this error occurs and how to solve it.

Understanding the Source of the Error

Directory Structure Mismanagement

One of the most common reasons for this issue is the misplacement of your API route files within the Next.js directory structure. Next.js has specific conventions for locating API route files, and placing them in the wrong directory can lead to unexpected behavior.

You might have an application structured like the following:

If your API file like.ts is located inside the /app/api directory while your requests are targeting the file in /pages/api, you will run into connectivity problems. This is because Next.js prioritizes the API routes defined in the /pages/api directory.

Solution Steps

Let's walk through how to resolve this problem:

Step 1: Locate the Correct Directory

Check where your like.ts file is currently residing. If it's in the /root/app/api folder, you need to move it or create it in the /root/pages/api directory.

Step 2: Ensure Proper Routing

Make sure that when you make your fetch requests in your application (like in useLike.ts), the API endpoint being called matches the path where the API file is located:

The above code correctly points to the right API endpoint, assuming like.ts is located in /pages/api.

Step 3: Test Your Setup

After making sure your file is in the correct location, test the DELETE functionality again. When you click the like button to remove a like, it should now successfully connect to your API and not throw a 405 Method Not Allowed error.

Conclusion

Errors like 405 Method Not Allowed can be tricky when you're navigating through API routes in Next.js. By simply ensuring that your API route files are in the correct directories, you can save yourself a lot of time and frustration.

If you run into issues like this in the future, always check your directory structure and ensure that your requests are targeting the right paths. Happy coding!
