Promets-moi

Tiny and effective javascript observer using promises.

Install

Requirements

You need to install Node.js (https://nodejs.org/) and NPM (installed with node). In your terminal you will now have access to npm which allows you to install modules stored on the internet and keep track of versions for you if those are updates.

Optional: Yarn is an alternative to NPM that build over it, sometimes makes downloading module faster by keeping some version cached. You can install with > npm i -g yarn

Installation

npm install promets-moi

Use

Pick an object A of any type, add a property b you want to observe, call promise = A.observe('b', valueOfInterest). Then handle the promise as you wish.

<script src="../lib/promets.min.js" charset="utf-8"></script>
<script type="text/javascript">
  var a = {lookAtThat:false}
  a.observe('lookAtThat').then(() => console.log("yaye"))
  setTimeout(() => {a.lookAtThat=true},3000)

  var b = [0,1]
  b.observe(0, "a").then(() => console.log('Even better!'))
  b[0] = "a"

  a.nested = {whatAboutThis: "nope"}
  a.nested.observe('whatAboutThis', "yep")
  .then(() => console.log('Amazed!'))
  setTimeout(() => {a.nested.whatAboutThis="yep"},2000)
</script>
