Caching allows you to temporarily store the return values of backend API calls and successful router calls on Wix's infrastructure, enabling quicker access to the data and improved site performance. While caching is effective, it’s important to invalidate caches when necessary to ensure that data always remains up to date. This helps preserve accuracy and prevents visitors from seeing outdated content.
The Cache API provides functionality for invalidating web method caches and router caches. Consider invalidating your caches when there are significant changes to your site's content or when your site pages display time-sensitive data. For example, if a product on your e-commerce site becomes out of stock, invalidating the cache of the web method that displays your products ensures that visitors see the most current status.
