Memoza

Description

Like _.memoize this one allows to cache functions and stores the results in FS.

Configuration

const memoza = require('node-memoza');
const wrapper = memoza({ cache: { path: cachePath } });

1. Remembers cb's arguments

const func = (param1, cb) => {
 setTimeout(() => { cb(param1); }, 10000);
}
const wrapped = wrapper(func);
wrapped(1234, (param) => console.log(param)); //will log "1234" in 10 seconds
// ...once cb called
wrapped(1234, (param) => console.log(param)); //will log "1234" without delay

2. Remembers Promise resolution value

const func = (param1) => {
 return new Promise((resolve) => {
   setTimeout(() => { resolve(param1); }, 10000);
 });
}
const wrapped = wrapper(func);
wrapped(1234).then((param) => console.log(param)); //will log "1234" in 10 seconds
wrapped(1234).then((param) => console.log(param)); // ...once promise has been resolved it will log "1234"
