Getting Started

In Node.js environment :

will update soon.

In Browser environment :

import Kihon from 'kihon'; // Import all components
import FullSizeBg from 'kihon/FullSizeBg' // Import single component. You can use tree-shaking. (https://webpack.js.org/guides/tree-shaking/)

Examples

Emitter

import Emitter from 'kihon/Emitter';

var emitter = new Emitter();

var subscribeHello = emitter.listen('hello', function(data) {
    console.log('hello :', data);
});

var subscribeWorld_1 = emitter.listen('world', function(data) {
        console.log('world_1 :', data);
    }),
    subscribeWorld_2 = emitter.listen('world', function(data) {
        console.log('world_2 :', data);
    });

// Unsubscribe subscriptions.
// subscribeHello.unsubscribe();
// subscribeWorld_1.unsubscribe();
// subscribeWorld_2.unsubscribe();

emitter.emit('hello', { value: 1 });
emitter.emit('world', { value: 99 });

/*
 * Emitter public methods
 */
// set event, event handler
// emitter.listen(event name, event handler);

// emii event
// emitter.emit(event name, data)

// dispose of all subscriptions
// emitter.dispose();
