使用Gulp自动化处理发布流程

当Angular应用发布时，开发者需要考虑以下问题：

MarkoCen

const EventEmitter = require('events');

const event = new EventEmitter();

// 添加一个事件监听器
event.on('bar', function() {
  console.log('bar fired!');
})

// 触发一个事件

MarkoCen

function isPromise(object){
  if(Promise && Promise.resolve){
    return Promise.resolve(object) == object;
  }else{
    throw "Promise not supported in your environment"
  }
}

var i = 1;
var p = new Promise(function(resolve,reject){

MarkoCen

import fs from 'fs';
import path from 'path';

const convert = (imgPath) => {
    // read image file
    fs.readFile(imgPath, (err, data)=>{
        // error handle
        if(err) {
            throw err;
        }
