<p>创建md文件并保存，完毕。</p>
<p>注意在md文件头部添加必要的<a href="https://hexo.io/zh-cn/docs/front-matter" target="_blank" rel="noopener"><code>front-matter</code></a>信息<br>，例如：</p>
<figure class="highlight plain"><table><tr><td class="gutter"><pre><span class="line">1</span><br><span class="line">2</span><br><span class="line">3</span><br><span class="line">4</span><br></pre></td><td class="code"><pre><span class="line">---</span><br><span class="line">title: Hexo博客使用说明</span><br><span class="line">date: 2020-01-08 18:53:59</span><br><span class="line">---</span><br></pre></td></tr></table></figure>

<p>许多项目脚手架默认就会把src目录添加一个<code>@</code>别名，项目中实际引入时，虽然可以精简路径，但也带来一个很麻烦的问题：<br>IDE无法识别这些别名，因此导致无法自动完成路径、无法识别引用资源的输出、出现不必要的告警等情况。</p>
<p>偶然发现vscode的web项目里有一个<code>jsconfig.json</code>文件，如：</p>
<figure class="highlight json"><table><tr><td class="gutter"><pre><span class="line">1</span><br><span class="line">2</span><br><span class="line">3</span><br><span class="line">4</span><br><span class="line">5</span><br><span class="line">6</span><br><span class="line">7</span><br><span class="line">8</span><br><span class="line">9</span><br><span class="line">10</span><br><span class="line">11</span><br><span class="line">12</span><br><span class="line">13</span><br></pre></td><td class="code"><pre><span class="line">{</span><br><span class="line"> <span class="attr">"compilerOptions"</span>: {</span><br><span class="line"> <span class="attr">"baseUrl"</span>: <span class="string">"."</span>,</span><br><span class="line"> <span class="attr">"paths"</span>: {</span><br><span class="line"> <span class="attr">"@/*"</span>: [<span class="string">"src/*"</span>]</span><br><span class="line"> },</span><br><span class="line"> <span class="attr">"target"</span>: <span class="string">"ES6"</span>,</span><br><span class="line"> <span class="attr">"module"</span>: <span class="string">"commonjs"</span>,</span><br><span class="line"> <span class="attr">"allowSyntheticDefaultImports"</span>: <span class="literal">true</span></span><br><span class="line"> },</span><br><span class="line"> <span class="attr">"include"</span>: [<span class="string">"src/**/*"</span>],</span><br><span class="line"> <span class="attr">"exclude"</span>: [<span class="string">"node_modules"</span>]</span><br><span class="line">}</span><br></pre></td></tr></table></figure>
<p>只要有这个文件，vscode就可以正常识别出别名了。</p>
<p>后来发现JetBrains家的IDE更简单，配置指定一下就行：</p>
<img data-src="/2020/01/08/%E8%AE%A9IDE%E8%AF%86%E5%88%ABwebpack%E7%9A%84%E5%88%AB%E5%90%8Dalias/1.png" class="">
<p>在项目设置的webpack标签页里，将配置文件指向<code><projectRoot>/node_modules/@vue/cli-service/webpack.config.js</code>即可。</p>
<p>保存并重新打开项目以后，不只<code>src</code>，所有的别名比如<code>utils</code>等等都可以被正常识别。</p>
<p>其实这都已经写在<code>vue-cli3</code>的<a href="https://cli.vuejs.org/zh/guide/webpack.html#以一个文件的方式使用解析好的配置" target="_blank" rel="noopener">文档</a>里了，只是原始表述不太直观，被我一直忽略了。</p>

<p>想实现一个转盘抽奖的需求，搜了一下现有的轮子，有的是用jQuery的动画函数实现的，有的是用canvas绘图然后再用高频率的setTimeout调用旋转方法，前者太老了没法简单移植到vue项目，后者感觉性能表现可能不会太好。也有一些用CSS动画的方案，设计了加速-匀速-减速三个动画，再计算偏转角度让三个动画尽可能无缝衔接，但我感觉绕了大远路，应该有更简单轻量的实现方案。个人更倾向于用transition来实现，不过网上的例子感觉还不够好，有的倾斜文字都没有对齐，最后还是自己手写了一个。核心思路是用transition以及rotate实现旋转动画，使用transition-origin和rotate绘制出定位较为精确的轮盘奖项，同时支持动态设置奖品数量。</p>
