Install

This project uses node and npm. Go check them out if you don't have them locally installed.

$ npm install --save brcast

Then with a module bundler like rollup or webpack, use as you would anything else:

// using ES6 modules
import brcast from 'brcast'

// using CommonJS modules
var brcast = require('brcast')

The UMD build is also available on unpkg:

<script src="https://unpkg.com/brcast/dist/brcast.umd.js"></script>

You can find the library on window.brcast.

Usage

import brcast from 'brcast'

let broadcast = brcast()

// subscribe
let unsubscribe = broadcast.subscribe(state => console.log(state))

// setState sets the state and invoke all subscription callbacks passing in the state
broadcast.setState(1)

// setState returns the current state
broadcast.getState()

// unsubscribe: invoke the function returned by broadcast.subscribe(state => console.log(state))
// to unbind the handler
unsubscribe()

Tests

$ npm run test
