Use defineAsyncComponent to Conditionally Render the Appropriate Error Page

In this lesson, we'll explore how to use Vue's defineAsyncComponent to conditionally load different error components based on the environment—development or production. By dynamically importing the appropriate error component, we optimize performance and ensure that developers see detailed error messages during development while end-users get simplified, user-friendly error pages in production. This approach leverages environment variables like import.meta.env.DEV to determine which component to load, providing flexibility and efficiency in handling errors across different environments.
