async-value

An AsyncValue represents a value that will exist in the future. This is different from a Promise in that it has no concept of errors or how they are handled.

Note that, unlike a Promise, this module is also internally synchronous. What this means is that if a value has already been set a call to get will trigger the callback immediately. Conversely, if any callbacks have already been assigned with get before a set occurs they too will run immediately when set is called. This behavior is intentional for performance reasons.

Install

npm install async-value

Usage

var value = new AsyncValue()
 
value.get(name => {
  console.log(`hello, ${name}!`)
})
 
value.set('world')
