A very simple signal library inspired by the signals package.

Installation

``sh $ npm install pico-signals`

This library is written in modern JavaScript and is published with both CommonJS and ES module transpiled variants.

If you target older browsers please make sure to transpile accordingly.

`Usage`

`js import picoSignals from 'pico-signals';

const listener1 = () => console.log('Listener 1'); const listener2 = () => console.log('Listener 2');

const ps = picoSignals();

const removeListener1 = ps.add(listener1); const removeListener2 = ps.add(listener2);

ps.dispatch('foo', 'bar'); //=> Both listeners will be called and both logs produced. //=> Every listener will receive the same arguments provided in the dispatch method.

removeListener2(); //=> Deleteslistener2 from the listeners list;

ps.dispatch(); //=> Onlylistener1 will be called since its currently the only listener on the list.

ps.clear(); //=> Clears all listeners.`
