<p>PWA本质上还是Web App，借助一些新技术也具备了Native App特性，兼顾两者优点</p>
<ul>
<li>渐进增强 ： 能够让每一位用户使用，无论用户使用什么浏览器，因为它是始终以渐进增强为原则</li>
<li>可安装 ： 可以像原生APP在主屏幕上留有图标</li>
<li>离线缓存 ：通过Service Worker使得 Web App 也可以做到像 Native App 那样可以离线使用、消息推送的功能</li>
<li>安全性 ： 通过 HTTPS 来提供服务来防止网络窥探，保证内容不被篡改</li>
</ul>
<p>PWA是一系列技术组成的集合，包括Manifest，Service Worker，Web Push等</p>
<p>涉及到的知识点：</p>
<ul>
<li>ES6标准语法</li>
<li>Promise</li>
<li>fetch，全新的获取资源的API，它包括Request、Response、Header和Stream</li>
<li>WebWorker，JavaScript解决单线程的方案</li>
<li>Cache API（缓存API）</li>

<p>路由的概念来源于服务端，而在Web前端的SPA应用中，路由主要用于建立URL和UI的映射关系，即URL 变化引起 UI 更新，无需刷新页面。</p>
<h3 id="前端路由"><a href="#前端路由" class="headerlink" title="前端路由"></a>前端路由</h3><p>前端路由主要解决两个问题：</p>
<ul>
<li>URL改变不引起页面刷新</li>
<li>检测URL变化</li>
</ul>
<p>常用方法有两种： hash mode和history mode</p>

<p>Typescript是JavaScript的超集，可以看做对JavaScript的一种强类型约束语言，与C#或Java的写法非常的相似，所以对从后端转前端的童鞋可以说是十分友好的。</p>
<p>最近提炼了公司的<a href="https://github.com/ChangbaFE/mars-multipages-seed" target="_blank" rel="external">基于Vue的多页应用的脚手架项目</a>，也想正好支持一些Typescript，增加多一些的选择。</p>

<h3 id="起因"><a href="#起因" class="headerlink" title="起因"></a>起因</h3><p>在公司搭建了套webpack多页面应用脚手架，开始用着很爽，解决了既想使用Vue的模块化开发，又想做多页打包上线管理的初衷，但是随着业务项目的增加，我发现npm run dev的时候，每次热加载，webpack的反应都很慢。</p>
<p>基本会卡在</p>
<figure class="highlight plain"><table><tr><td class="gutter"><pre><div class="line">1</div><div class="line">2</div></pre></td><td class="code"><pre><div class="line">94% assets optimization</div><div class="line">95% emitting</div></pre></td></tr></table></figure>
<p>这个步骤很久</p>
<p>准备具体定位一下问题的原因。由于项目基于vue-cli改写的多页应用脚手架，手动重写了HtmlWebpackPlugin插件，所以基本猜测和这个有关，后来证明也真的是这个引起的。</p>
<p>我们可以在package.json中启动dev的时候添加–profile命令，去看启动的详情。</p>
<p><img src="/img/FrontEnd/webpack/1/dev-slow.jpg?v=1" alt=""></p>
<p>我们可以看到，asset optimization过程耗时2s左右，有时候会更长，所以基本确定就是这个地方卡住了HMR。</p>
<p>那么问题来了，怎么优化这里？</p>

<p>最近遇到一点fastclick的报错，追踪下去，发现对于fastclick的源码其实并没有很好地理解清楚，找了些资料，决定重新读一遍。</p>
<h3 id="起因"><a href="#起因" class="headerlink" title="起因"></a>起因</h3><p>移动端click事件有300ms延迟</p>
<p>300ms延迟的原因： 移动端有一个双击缩放功能，浏览器需要判断用户点击是否为双击缩放</p>
<p>导致的结果：</p>
<ul>
<li>用户体验差，很不流畅，尤其是在密集操作场景下，比如计算器等操作时，感觉反应很慢</li>
<li>会有点击穿透问题</li>
</ul>
