poke-js

A small reactivity system

Usage

Import poke-js by including the following script tag in your HTML:

<script src="https://unpkg.com/poke-js"></script>

The global variable Poke is now available with the init & watch methods. Use these to initialize your data object and add 'watcher' functions to be run whenever any of their data dependencies are updated.

const { init, watch } = Poke
 
let data = { price: 5, quantity: 2 }
init(data)
 
// total output
const totalOutput = document.getElementById('totalOutput')
watch(() => totalOutput.innerText = data.price * data.quantity)

In this example, any changes to the price or quantity properties of data, will update the DOM element with the id totalOutput.

The properties of the data passed to Poke.init() are also easily bound to the value & innerText of DOM elements by using the data-bind attribute.

Price: <span data-bind="price"></span>

Furthermore, poke-js will listen to input events on any element with the data-input attribute and reflect the change in the corresponding data value.

<input data-input="quantity" type="number" />
