A tiny utility to cache function outputs easily.
npm i cache-funcimport { cacheFunc } from 'cache-func';
function expensiveCalculation() {
// it could be here anything here, like a long loop, a network request, etc.
console.log('Calculating...');
return 42;
}
const cachedCalculation = cacheFunc(expensiveCalculation, {
maxAge: 5 * 60 * 1000, // Cache for 5 minutes
});
console.log(cachedCalculation()); // Logs "Calculating..." and then "42"
console.log(cachedCalculation()); // Logs "42" without recalculatingWraps a function fn and returns a new function that caches the result of fn's first call and returns the cached result on subsequent calls.
