How Do You Add Custom Error Handling To Your Flask App? Are you interested in making your Flask web applications more user-friendly and professional? In this detailed video, we'll guide you through the process of adding custom error handling to your Flask apps. You'll learn how to handle common errors like 404, 400, and 500, as well as how to create your own custom exceptions for specific issues. We’ll show you how to write error handler functions that return clear, helpful responses—whether in JSON format for APIs or HTML pages for websites.

We’ll also demonstrate how to connect these handlers to your Flask app using the errorhandler decorator, ensuring your app responds consistently when errors occur. Additionally, you'll see how to manually trigger errors with the abort() function, which allows you to control error responses dynamically based on your app’s logic. For a more polished user experience, we’ll cover how to return custom error pages using templates like 404.html, making your app look more professional.

By the end of this video, you'll understand how to define, register, and use error handlers effectively, improving your app’s reliability and user interactions. Whether you're building an API or a web interface, mastering custom error handling is a key skill for backend development.
