      <h4>Compose</h4>
    </figcaption>
</figure>

<p>最近 JetBarin 公司发布了 <a href="https://www.jetbrains.com/lp/compose/" target="_blank" rel="noopener noreferrer">Compose Desktop</a>。是的，你没听错，就是 Google 用于Android 上的 <a href="https://developer.android.com/jetpack/compose?hl=zh-cn" target="_blank" rel="noopener noreferrer">Compose</a>。</p>
<blockquote>
  <p>Jetpack Compose 是用于构建原生 Android 界面的新工具包。Jetpack Compose 使用更少的代码、强大的工具和直观的 Kotlin API 简化并加快了 Android 上的界面开发。</p>

</blockquote><p>而现在，就可以编写同样的UI层代码，然后运行到 Android 和 DeskTop 了。不难发现，这是 kotlin 一直在搞的套路，多平台共享代码。</p>
<p>使用了 Skia 进行硬件加速( 就是Flutter使用的 Skia )，可以与 AWT 和 Swing 进行互操作。</p>
<p>让我们先来一个 Hello World 试试水。</p>
<h2 id="新建-compose-项目" class="headerLink">
    <a href="#%e6%96%b0%e5%bb%ba-compose-%e9%a1%b9%e7%9b%ae" class="header-mark"></a>新建 Compose 项目</h2><p>你可以更新到最新的idea 2020.3(目前还是beta)，或者从 <a href="https://github.com/JetBrains/compose-jb/tree/master/templates/desktop-template" target="_blank" rel="noopener noreferrer">Github</a> 上拉取它的模板。这里我选择使用 idea。</p>
<p>在 kotlin 选项中找到  JetBrains Compose ,选择 Desktop uses Kotlin。</p>
<p><img class="tw-inline" loading="lazy" src='https://island-hexo.oss-cn-beijing.aliyuncs.com/new_compose.png'     ></p>
<p>创建完成后等待 gradle 依赖下载。</p>
<p>但是在这里会出现问题，运行是报下面的错。</p>
<blockquote>
  <p>org/jetbrains/kotlin/cli/common/PropertiesKt</p>
<p>org.jetbrains.kotlin.cli.common.PropertiesKt</p>
<p>Try:
Run with &ndash;stacktrace option to get the stack trace. Run with &ndash;info or &ndash;debug option to get more log output. Run with &ndash;scan to get full insights.</p>

</blockquote><p>经过排查，这是由 Gradle 和 java 14 引起的，Gradle 6.6 的版本会引起该问题，可以将gradle更改到 6.7 或者 6.5 重新进行构建。我这里修改到 6.5.1</p>
<p>目前 compose 的版本为 113 , 而通过 idea 创建的 版本为 63，所以更新版本。</p>
<p>以下为官方的 gradle.kts 配置</p>

<p>通过通过点击按钮，来更改 text，从而来刷新界面。基本和其他声明式 UI ，大同小异，比如 flutter，swiftUI 等。</p>
<p>基本使用控件使用可以参考 <a href="https://developer.android.com/reference/kotlin/androidx/compose/ui/package-summary?hl=zh-cn" target="_blank" rel="noopener noreferrer">androidx.compose</a> 文档。</p>
<p>针对桌面做了一些扩展，比如鼠标，键盘事件，系统的原生通知，系统的托盘菜单。</p>

    <a href="#%e6%89%93%e5%8c%85" class="header-mark"></a>打包</h2><p>开发完成的应用可以直接打包为平台可执行文件。我使用的是 windows 平台。通过 <code>packageMsi</code> 命令打包为 exe 应用。</p>
<p>这里会下载 <a href="https://github.com/wixtoolset/wix3" target="_blank" rel="noopener noreferrer">wix3</a> 。</p>

<p>这里可能会出现下载失败，如果下载失败，请手动到 Github 下载 wix311-binaries.zip。然后将文件命名为 wix311.zip 放在 build/wixToolset 下，重新运行 packageMsi  。</p>
<p>当你认为你要编译成功时， Gradle 再次报错。</p>

<p>在 Gradle 中添加版本号。</p>

    <a href="#%e6%80%bb%e7%bb%93" class="header-mark"></a>总结</h2><p>目前来说，项目还有很多 bug，毕竟才 Alpha，而且官方文档也有错误。例如打包这一块，很多问题需要自己摸索。</p>
<p>例如中文输入法的输入的情况下报错。</p>
<blockquote>
  <p>Exception in thread &ldquo;AWT-EventQueue-0 @coroutine#2&rdquo; java.lang.NullPointerException: event.text must not be null。</p>

</blockquote><p>图标显示问题，在我这里显示一个黑框框。</p>

<p>但是，jvm 上的 GUi 技术有了新的发展未尝不是一件好事，可以一处编写，多端运行。</p>

<p>每次我都是将用的关键技术告诉他，按道理讲搭建博客的技术网上的文章应该有很多很多了。但是我还是打算自己写一下教程，方便更多的人来进行学习和搭建博客的使用。</p>
<h2 id="hugo" class="headerLink">
    <a href="#hugo" class="header-mark"></a>Hugo</h2><p>目前我的博客由之前的 Hexo 迁移到 Hugo，Hugo 无论是安装，配置还是部署个人感觉都比 Hexo 方便太多了。Hugo 的安装仅仅需要一个安装包。可以在 <a href="https://github.com/gohugoio/hugo/releases" target="_blank" rel="noopener noreferrer">Github</a> 上找到你的对应版本，进行安装。</p>
<p>Hugo 是有 Go 语言写的，从 markdown 渲染 html 的速度很快。自称为 <strong>世界上渲染网站最快的框架</strong>。另外 Hugo 也有很多的<a href="https://themes.gohugo.io/" target="_blank" rel="noopener noreferrer">主题</a>，可以供我们选择。</p>
<h2 id="安装" class="headerLink">
    <a href="#%e5%ae%89%e8%a3%85" class="header-mark"></a>安装</h2><p>安装完记得将 Hugo 添加到环境变量中。在终端进行 <code>hugo version</code> 进行验证是否安装正确。</p>
<p>是的，安装就是如此的简单，官方提供了其他安装方式，你可以选择<a href="https://gohugo.io/getting-started/quick-start/" target="_blank" rel="noopener noreferrer">官方</a>提供的方式。</p>
<h2 id="建站" class="headerLink">
    <a href="#%e5%bb%ba%e7%ab%99" class="header-mark"></a>建站</h2><p>通过 Hugo 的命令我们可以快速生成我们的网站。你可以选择你喜欢的地方来执行下面的命令。</p>

<p>设置完代理之后就可以安装我们的 cli 了。</p>
<p>通过 npm 进行安装 <code>npm install -g firebase-tools</code> 这样就完成了安装。</p>
<p>安装完成后首先是登录。<code>firebase login</code> 进行登录，会打开浏览器进行授权。这个过程使用全局代理，否则有可能无法验证通过。</p>
<p><img class="tw-inline" loading="lazy" src='https://island-hexo.oss-cn-beijing.aliyuncs.com/firebase-login-success.png'     ></p>
<p>在项目的根目录下执行 <code>firebase init</code> 。选择 Hosting，通过<strong>空格</strong>进行确认。</p>
<p><img class="tw-inline" loading="lazy" src='https://island-hexo.oss-cn-beijing.aliyuncs.com/firebase%20hosting.png'     ></p>
<p>之后选择 Use an existing project。从项目列表里找到我们刚刚创建的项目。<code>回车</code>继续。下一步是询问是否使用public 目录。这里直接回车就好。因为public目录就是我们要进行部署的文件。</p>
<p>是否要重写 index.html ，这里可以选择不重写。</p>
<p>这样我们的项目就已经安装创建完成。</p>
<p><img class="tw-inline" loading="lazy" src='https://island-hexo.oss-cn-beijing.aliyuncs.com/firebase%20init.png'     ></p>
<p>完成了创建，那么下一步就是要部署。</p>
<h3 id="部署到-firebase-上" class="headerLink">
    <a href="#%e9%83%a8%e7%bd%b2%e5%88%b0-firebase-%e4%b8%8a" class="header-mark"></a>部署到 firebase 上</h3><p>通过命令firebase deploy 就可以将我们的编译后的网页部署到 firebase 上去。</p>
<p>执行完成后下方会告诉我们项目控制台的地址和项目地址，我们可以打开项目地址进行项目的查看。</p>
<p><img class="tw-inline" loading="lazy" src='https://island-hexo.oss-cn-beijing.aliyuncs.com/firebase-deploy.png'     ></p>
<p>但是，当我们打开项目的时候，发现上面没有样式。通过浏览器控制台可以看到样式文件并没有被请求到。</p>
<p>这里需要我们手动设置一下。</p>
<p>打开项目的 config.toml 文件，第一行的 <code>baseURL</code> 进行修改，将它修改为我们firebase给的网站地址。</p>
<p>重新进行 <code>hugo</code> 和 <code>firebase deploy</code>。 刷新页面后，可以看到我们的网站已经有了样式，重新部署到 firebase 上了。</p>
<h2 id="集成-cicd" class="headerLink">
    <a href="#%e9%9b%86%e6%88%90-cicd" class="header-mark"></a>集成 CI/CD</h2><p>话说，每次写完文章都要来一串命令，很费事，也容易出错。所以我们可以集成 CI/CD 来进行部署。</p>
<p>这里我选择了 Gitlab 自带的 CI/CD 功能。方便快捷。</p>
<p>通过命令 firebase login:ci 进行重新登录授权，此时授权完成之后就会在终端上出现一行 token。</p>
<p><strong>请把 token 保存好</strong>。</p>
<p>在项目根目录建立 CI/CD 执行文件,命名为 <code>.gitlab-ci.yml</code>。粘贴下面的代码。</p>

<p>将项目上传到 gitlab 上。打开项目设置，找到 CI/CD 目录。在Key的位置填入 <strong>FIREBASE_TOKEN</strong> ，在 Valeu 中填入我们刚刚记下的 Token，并保存。</p>
<p><img class="tw-inline" loading="lazy" src='https://island-hexo.oss-cn-beijing.aliyuncs.com/gitlab-variables.png'     ></p>
<p>当这些完成后，选择 CI/CD 目录，点击 Run Pipeline 进行重新运行。</p>
<p>等待运行完成之后，项目就会自动部署到 Firebase 了。</p>
<p>从此以后，我们只需要负责写文章就好，编译，部署都提交到 gitlab 服务器上进行。</p>

<p>Kotlin 不仅仅是能写Android，而且可以写服务端，可以说只要可以写Java的地方，就可以用Kotlin来进行替换。当然Kotlin远不止这些。目前Kotlin可以做到以下平台的开发和使用。jvm,android,js和native(beta)。正因为可以开发 Native ，所以Kotlin现在对 ios 开发也是支持的，虽然看起来效果不是那么的好。</p>

<p>今天进行的 Kotlin 进行 react 开发，这只是对 KotlinJs 的一次尝试和使用。</p>

    <a href="#%e5%ae%89%e8%a3%85%e7%8e%af%e5%a2%83" class="header-mark"></a>安装环境</h1><p>很早以前，kotlin 官网就出现了两个库，这两个库基本就是来完善 react 在 kotlin 中的生态，第一个是 <a href="https://github.com/JetBrains/create-react-kotlin-app" target="_blank" rel="noopener noreferrer">JetBrains/create-react-kotlin-app</a> ，一个生成 React 工程的脚手架；第二个是<a href="https://github.com/JetBrains" target="_blank" rel="noopener noreferrer">JetBrains/kotlin-wrappers</a> ，该库里存放了 react 周边生态组件，比如说 router，redux 等等。</p>
<p>按照脚手架文档，一行代码便能生成我们的项目。</p>

<p>我们用 <code>@file:JsModule(&quot;antd/lib/button&quot;)</code> 来表明绑定目录。通过 <code>@JsName(&quot;default&quot;)</code> 来进行绑定，此时需要该控件是以 <code>export default Button;</code></p>

<p>等待自动编译和刷新完成，查看我们的页面。</p>
<p><img class="tw-inline" loading="lazy" src='https://island-hexo.oss-cn-beijing.aliyuncs.com/ant-button.gif'     ></p>
<p>终于见到了我们的按钮了，而且样式和 Ant 官方文档上所示一致。</p>
<p>说明我们的绑定现在已经成功。</p>
<p>然后如法炮制，把其他的要使用控件进行同样的绑定。</p>
<p>我们 input 和 search 进行绑定。</p>
<p>此次绑定与上次有所改变，我们对这两个属性可以设置一些值，以便我们在 HTML DSL 中直接使用。这里我们通过实现 <code>RProps</code> 来重新定制了我们要使用的属性,对 <code>Input</code> 设置了一个 <code>placeholder</code>,而 <code>SeacherRPorps</code> 可以直接继承 <code>InputRProps</code> 来进行属性上的扩展。</p>

<p>重新等待页面刷新，出现了我们预想的结果。每次点击按钮就会数字就会进行累加。</p>

    <a href="#%e6%80%bb%e7%bb%93" class="header-mark"></a>总结</h1><p>首先声明 作者并非专业前端，所以文章中有错误还望指正；本文更重要的目的是为了表明 kotlin 在其他领域的使用和使用体验。</p>
<p>kotlin 写 react,在书写习惯上应该和 ts 写是差不多的，而且给后端同学带来了写前端的体验。但是生态不完整，就一个 UI 组件库没有一个官方用 kt 写的，而且编译速度慢，报错有时不明显，可查阅资料少。不过要说硬着头皮开发，个人感觉是完全可以的，不过估计要自己造不少轮子。</p>

<p>选择 新建 Dart项目，创建一个 Flutter Web App。</p>
<p>项目创建好，要等待 依赖包的下载。</p>
<p>一边让IDEA下载，我们一边去做另一件事情</p>
<h2 id="安装-webdev-工具" class="headerLink">
    <a href="#%e5%ae%89%e8%a3%85-webdev-%e5%b7%a5%e5%85%b7" class="header-mark"></a>安装 webdev 工具</h2><p>我们需要官方提供的 <code>webdev</code> 工具来为我们编译。打开 <code>flutter_web</code> Github 网站 <a href="https://github.com/flutter/flutter_web" target="_blank" rel="noopener noreferrer">Github</a> 在 <strong>Getting Started</strong> 中找到 <strong>Install the flutter_web build tools</strong> ，详细说明了如何安装 <code>webdev</code> 工具，其实也就是一行命令的事情。</p>
<p>运行下面的命令。</p>
<blockquote>
  <p>$ flutter packages pub global activate webdev</p>

</blockquote><p>安装完成后，我们要找到 <code>flutter</code> 的安装目录，在目录的 <code>.pub-cache/bin</code> 中会找到我们下载的 <code>webdev</code></p>
<p><img class="tw-inline" loading="lazy" src='https://island-hexo.oss-cn-beijing.aliyuncs.com/devinstall.jpg'   alt="webdev"  ></p>
<p>确保安装成功 <code>webdev</code> 后 ，将路径 <code>$HOME/.pub-cache/bin</code> 添加到环境变量中。</p>
<p>设置完成后在终端输入 <code>webdev</code> 看看是否成功</p>
<p><img class="tw-inline" loading="lazy" src='https://island-hexo.oss-cn-beijing.aliyuncs.com/webdev%20cmd.jpg'     ></p>
<p><strong>坑</strong>：在一些终端上运行该命令会提示该命令不存在，比如 cmd,Fluent。</p>
<p>配置成功后就可以开始下一步了。</p>
<h2 id="运行项目" class="headerLink">
    <a href="#%e8%bf%90%e8%a1%8c%e9%a1%b9%e7%9b%ae" class="header-mark"></a>运行项目</h2><p>首先确保 IDEA 将所需要的依赖正常安装完成。</p>
<p>在终端输入 <code>webdev serve</code>,当编译完成后，打开 http://localhost:8080, 如图，显示出 <code>hello world</code></p>
