Memoize the last result, in async way.
async-memoize-one simply remembers the last arguments, and if the function is next called with the same arguments then it returns the previous result.
It's used for micro-caching scenarios, where you want to prevent perform an action previously done during a short period of time.
No need to worry about cache busting mechanisms such as maxAge, maxSize, exclusions and so on which can be prone to memory leaks.
Install
1$ npm install async-memoize-one --save
Usage
1const get = require('util').promisify(require('simple-get')) 2const memoizeOne = require('async-memoize-one') 3 4const fetchData = memoizeOne(url => get(`https://api.microlink.io?url=${url}`)) 5 6;(async () => { 7 // fecthing data for first time 8 console.time('fetch') 9 await fetchData('https://example.com/one') 10 console.timeEnd('fetch') 11 12 // served data from cache; no fetching! 13 console.time('fetch') 14 await fetchData('https://example.com/one') 15 console.timeEnd('fetch') 16 17 // previous execution parameters are different, so fetching again 18 console.time('fetch') 19 await fetchData('https://example.com/two') 20 console.timeEnd('fetch') 21 22 // previous execution parameters are different, so fetching again 23 console.time('fetch') 24 await fetchData('https://example.com/one') 25 console.timeEnd('fetch') 26})()
