CacheResolver

Summary

In-memory cache to retrieve and set values based on promise resolution.

Usage

Node.js

Install to your project using npm:

npm install cache-resolver --save-dev

Use it:

var CacheResolver = require('cache-resolver');
var cache = new CacheResolver();
 
// first resolve, uses callback to resolve promise and save in cache
cache.resolve({
  key: 'cache-key',
  callback: function() {
    return new Promise(function(resolve, reject) {
      // perform some asynchronous operation
      setTimeout(function() {
        resolve('success');
      }, 500);
    });
  }
}).then(function(result) {
  console.log(result); // 'success'
});
 
// second resolve, run in parallel to first, reuses first callback promise
cache.resolve({
  key: 'cache-key',
  callback: function() {
    return new Promise(function(resolve, reject) {
      // perform some asynchronous operation
      setTimeout(function() {
        resolve('callback will not be used');
      }, 500);
    });
  }
}).then(function(result) {
  console.log(result); // 'success'
});
