The _findCategoryByAlias method allows you to retrieve a category by its alias. It uses caching and local storage to optimize performance, reducing the need for repeated API calls. This method is useful when you need to find a specific category using its alias, such as for navigation, display, or filtering purposes.
The first parameter is the alias, which is a unique identifier (or slug) associated with the category. You can pass this alias as a string to find the corresponding category.
2.
Define a Callback Function:
The second parameter is a callback function. This function will be executed once the category is retrieved. The retrieved category object will be passed as an argument to this function.
3.
Handle Retrieved Category:
Inside your callback function, you can process the retrieved category. This might involve displaying the category details on the UI, using it for navigation, or performing other category-related actions.
Use this method to navigate users to a specific category page based on its alias, such as when a user clicks on a category link.
2.
Category Display:
This method is helpful for displaying category details on a page where the category alias is used to identify which category should be shown.
3.
Optimized Data Retrieval:
By leveraging caching and local storage, this method ensures that category data is fetched efficiently, making it ideal for scenarios where category information is frequently accessed.
Caching: The method caches the categories in memory (_cache_categories) and in local storage to improve performance. If the cache is available, it will be used instead of making an API call.
Language-Specific Data: The method retrieves category data based on the current language setting, ensuring that users see the correct language version of the categories.
Asynchronous Process: Since the method may involve an API call, the callback function will be executed asynchronously once the data is retrieved.
This method is a practical tool for finding and using category data based on aliases, providing flexibility in handling category-related operations in your application.
