Fun cache
This is the fun and cache.
How does it work:
It stores a map of results of a function and uses arguments as keys, for faster response,
Note that if the function result in different results with the same argument, the cache wouldn't work.
How to use:
import funcache from "func-cache";
const cachedFibonacci = funcache((num: number) => {
// ... your function here
}, options); // about the options, see below
console.log(cachedFibonacci(1000)); //-- viewing the result
console.log(cachedFibonacci.noCache(1000)); //-- run without caching
console.log(cachedFibonacci.clearCache()); //-- to clear the cacheOptions:
import funcache, { localStorageCacher, fSCacher, redisCacher, upstashCacher } from "func-cache";
const options = {
// (1 sec) in miliseconds
lifeTime: 1000,
/** debounce time wait to call onDataUpdate, default 1000ms */
debounceTimer: 200,
/** incase the call is async, (sometimes the script doesn't detect it's async and wont run the await for it) default: false */
async: true,
// place to store the cache, incase of restarts (browser only)
...localStorageCacher("_cachePlace_for_fibonacci"),
// place to store the cache, incase of restarts (server only). fs way
...fSCacher("./_cachePlace_for_fibonacci.json"),
// place to store the cache, incase of restarts (server only). redis way
...redisCacher("_cachePlace_for_fibonacci", {
client: redisClient,
}),
// place to store the cache, incase of restarts (server only). upstash way
...upstashCacher("_cachePlace_for_fibonacci", {
client: upstashClient,
}),
};
