A quick example

npm i @jojy/event-bus -S

import eventBus from '@jojy/event-bus';

// bind
eventBus.on('back', e => console.log(`1: ${e}`))
eventBus.on('back', e => console.log(`2: ${e}`), 1)  // just callback once
eventBus.on('back.pageA', e => console.log(`3: ${e}`))  // with namespace

// emit
eventBus.emit('back', 'test')
// 1: test  2: test  3: test

eventBus.emit('back', 'test')
// 1: test  3: test

eventBus.emit('back.pageA', 'test')
// 3: test

// unbound
eventBus.off('back.pageA')  // only unbound back.pageA
eventBus.off('back')  // unbound all back

Method

• on(key, function, times)，subscribe message
• emit(key, data)，publish message
• off(key)，remove the subscription

Introduction

• support namespace, use key.namespace as a key, just like Jquery on.
• can set callback times, for example: eventBus.on(key, callback, 1), it will execute once only.
