memo-swr - Memoization with Stale-While-Revalidate and Enhanced Customization
This module provides two memoization functions, memoSwr
and memoSwrExtra
, that leverage the Stale-While-Revalidate caching strategy for asynchronous functions. The memoSwr
function provides basic memoization capabilities, while memoSwrExtra
enhances the memoization with support for custom cache creation and key generation functions.
Features
- Memoizes the results of asynchronous functions with a Time-To-Live (TTL)
- Automatically updates the cache in the background after the TTL has expired
- Uses Stale-While-Revalidate strategy to serve stale data while updating the cache
- Custom cache implementation support (
memoSwr
) - Supports custom cache creation functions and key generation functions (
memoSwrExtra
) - Integrates with
cache-manager
for flexible caching options (memoSwrExtra
)
Usage
Both functions have similar usage patterns, with memoSwrExtra
offering additional options for customization.
Importing the module
import { memoSwr, memoSwrExtra } from './memo-swr';
Using the memoSwr or memoSwrExtra function
// Async function to memoize
async function fetchData(url: string): Promise<any> {
const response = await fetch(url);
return response.json();
}
// Memoize options
const options = {
ttl: 60000, // Time-To-Live in milliseconds
};
// Create a memoized version of fetchData using memoSwr
const memoizedFetchData = memoSwr(fetchData, options);
// or using memoSwrExtra with additional customization
const memoizedFetchDataExtra = await memoSwrExtra(fetchData, {
...options,
createCache: createCustomCache,
keyGenerator: customKeyGenerator,
});
// Usage of memoized function
(async () => {
const data = await memoizedFetchData('https://api.example.com/data');
console.log(data);
})();
Refer to the previous responses for detailed documentation on how to use memoSwr
and memoSwrExtra
, as well as implementing custom cache creation and key generation functions.
