The _findCategoriesByIds method is designed to retrieve a list of categories based on their IDs. It efficiently manages category data by leveraging caching and local storage, reducing the need for repeated API requests. You can use this method to get specific categories by their IDs and then perform further actions with the retrieved data.
The first parameter is an array of category IDs (ids). These IDs represent the categories you want to retrieve. If you want to fetch multiple categories, simply include all the relevant IDs in the array.
2.
Define a Callback Function:
The second parameter is a callback function. This function will be executed once the categories are retrieved. The retrieved categories will be passed as an argument to this function.
3.
Handle Retrieved Categories:
Inside your callback function, you can process the retrieved categories. This might involve displaying them on the UI, using them for filtering or searching, or performing other category-related actions.
Use this method when you need to display specific categories, such as in a product listing or category overview page.
2.
Category Filtering:
This method is helpful when you need to filter or search for items based on their categories. Retrieve the categories by their IDs and then apply the necessary filters.
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 needed frequently.
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 convenient way to fetch specific categories by their IDs and provides flexibility in handling the retrieved data for various application needs.
