Resolving Laravel Controller Not Found Error When Using src Folder Architecture

If you are implementing a clean architecture in Laravel and have moved your code to a src folder, you may encounter an error where Laravel can’t find your controllers located in this new structure. This can be frustrating, especially when you think you've followed the proper steps to set everything up correctly. One common error you might see reads:

In this guide, we’ll walk through the steps to troubleshoot and resolve this issue, ensuring that your controllers are recognized by Laravel.

Understanding the Problem

The problem arises largely due to how Laravel handles autoloading and namespaces. When you move your controllers to a different directory, you must ensure that Laravel knows where to find these controllers through the appropriate configuration in composer.json.

What's Happening?

Namespace Configuration: The namespace in your controller does not match the expected structure.

Composer Autoloading: Laravel must know about the new folder structure to autoload your classes properly.

Let’s go through the solution step by step.

Solution Steps

Step 1: Update Your Namespace

Make sure that the namespace in your NotebooksController is defined correctly. Based on PSR-4 standards, it should follow the convention:

Step 2: Modify the Composer Autoload Section

Next, you need to add your src folder to the composer autoload configuration. Open your composer.json file and ensure you have the following structure:

This addition tells Laravel to look in the src directory when autoloading classes that are prefixed with the Src namespace.

Step 3: Regenerate the Autoload File

After modifying your composer.json, you need to regenerate the autoload files by running the following command in your terminal:

This command updates the autoloader to include your new namespace configuration.

Step 4: Adjust Your Routes

When you call your controller from routes/web.php, ensure you're referencing the correct namespace. Your route should look like this:

This adheres to the updated naming convention, allowing Laravel to locate your NotebooksController.

Conclusion

After following the steps outlined above, you should be able to resolve the issue of Laravel not finding controllers in your custom src folder. Always ensure that:

Your namespaces are declared correctly.

The composer autoload configuration is up-to-date.

The commands to clear and regenerate the autoload files are executed after any modifications.

By adhering to these recommendations, you can successfully implement a clean architecture in Laravel while ensuring that your application's structure is both organized and functional. If you continue to experience issues, re-check the paths, namespaces, and autoload configurations to ensure everything is aligned.

Happy coding!
