Error Templates Should Only Be Responsible For Mapping The State To The Ui Avoid Placing Tags With Side Effects In Your Templates Such As

As a software engineer, you're probably familiar with the concept of error templates within your application. These templates play a crucial role in how errors are displayed to users and how they interact with your system. However, when it comes to effectively managing error templates, one key principle to remember is to keep them focused on mapping the state to the UI, without introducing any unnecessary side effects.

A common mistake that developers often make is placing tags with side effects directly in their error templates. While it may seem convenient to handle everything in one place, this practice can lead to a range of issues down the line. By separating concerns and maintaining a clean structure, you can improve the maintainability and readability of your codebase.

When designing error templates, it's essential to remember that their primary purpose is to present the error information to the user in a clear and concise manner. Any additional logic or functionality should be kept separate from the template itself. Instead, consider handling side effects, such as logging or analytics tracking, in dedicated error-handling code outside of the template.

By adhering to this best practice, you not only make your code more modular and reusable but also enhance the overall user experience. Separating concerns allows you to focus on each aspect of error handling independently, making it easier to debug and troubleshoot issues when they arise.

To implement this approach effectively, start by identifying the core responsibilities of your error templates. These should include displaying the error message, providing relevant context, and guiding users on how to proceed. Avoid mixing these responsibilities with actions that could introduce side effects, such as sending requests to external services or modifying the application state directly.

Instead, consider using a structured approach, such as a model-view-viewmodel (MVVM) design pattern, to handle error templates. By encapsulating the logic for error handling in a separate viewmodel, you can maintain a clean separation of concerns and ensure that each component of your application performs its intended role efficiently.

In conclusion, error templates should focus on mapping the state to the UI without incorporating tags with side effects. By following this best practice, you can streamline your development process, improve code quality, and deliver a more robust and user-friendly experience. Remember, clean and maintainable code is key to building reliable and scalable software solutions.
