Versions

Last version

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')
