Memoize

A decorator that memoizes the result of a method, improving performance by caching return values for the same input arguments. It also clears the cache on component destroy.

This Decorator uses memoizee as dependency!

Description

The @Memoize() decorator is used to optimize methods within Angular components or services by caching the results of function calls. This is particularly useful for computationally expensive methods or methods that fetch data from external sources, where repeated calls with the same arguments would otherwise lead to redundant computations or network requests. The cache will be cleared when component destroyed.

Usage

Apply the @Memoize() decorator directly above the method you wish to memoize. Make sure the class using the @Memoize decorator implements the OnDestroy lifecycle hook, even if you don't have any other custom logic. This ensures that ngOnDestroy is defined, and the decorator's cache clearing logic will be executed.
