In handling validation errors and user feedback, I employ a combination of client-side and server-side validations. Client-side validations are implemented using JavaScript to provide immediate feedback on input fields. This enhances the user experience by reducing unnecessary server requests.
Server-side validations are crucial for data integrity and security. They’re performed regardless of client-side validations as they can be bypassed. In languages like Python, libraries such as Marshmallow are used for this purpose.
For user feedback, I use both synchronous and asynchronous methods. Synchronous feedback is provided immediately after an action, while asynchronous feedback is delivered later via email or notifications.
Error messages are clear, concise, and specific to help users understand what went wrong and how to fix it. For accessibility, ARIA roles and alerts are used to make error messages perceivable to all users.
