es-next-tools/dist/types/function/memoizeAsync.d.ts

A comprehensive utility library for JavaScript and TypeScript that provides a wide range of functions for common programming tasks, including mathematical operations, date manipulations, array and object handling, string utilities, and more.

import type { AnyFunction } from '..';
/**
 * Creates a memoized version of an asynchronous function.
 * @param {AnyFunction} fn - The asynchronous function to memoize.
 * @param {number} [expirationTime=60000] - Time in milliseconds before cache expires.
 * @returns A memoized version of the input function.
 * @example
 * const memoizedFetch = memoizeAsync(async (url: string) => {
 *   const response = await fetch(url);
 *   return response.json();
 * });
 *
 * // First call will fetch data
 * const data1 = await memoizedFetch('https://api.example.com/data');
 * // Second call with the same URL will return cached data
 * const data2 = await memoizedFetch('https://api.example.com/data');
