Ant Design React 致力于提供给程序员愉悦的开发体验。
在开始之前，推荐先学习 React 和 ES2015，并正确安装和配置了 Node.js v8 或以上。官方指南假设你已了解关于 HTML、CSS 和 JavaScript 的中级知识，并且已经完全掌握了 React 全家桶的正确开发方式。如果你刚开始学习前端或者 React，将 UI 框架作为你的第一步可能不是最好的主意。
第一个例子
这是一个最简单的 Ant Design 组件的在线 codesandbox 演示。
<h3 id="user-content-1-创建一个-codesandbox">1. 创建一个 codesandbox</h3> <p>访问 http://u.ant.design/codesandbox-repro 创建一个 codesandbox 的在线示例，别忘了保存以创建一个新的实例。</p> <h3 id="user-content-2-使用组件">2. 使用组件</h3> <p>直接用下面的代码替换 <code>index.js</code> 的内容，用 React 的方式直接使用 antd 组件。</p> <pre><code class="chroma language-jsx"><span class="kr">import</span> <span class="nx">React</span><span class="p">,</span> <span

<p>你可以在组件页面的左侧菜单查看组件列表，比如 <a href="/components/alert-cn">Alert</a> 组件，组件文档中提供了各类演示，最下方有组件 API 文档可以查阅。在代码演示部分找到第一个例子，点击右下角的图标展开代码。</p> <p>然后依照演示代码的写法，在之前的 codesandbox 里修改 <code>index.js</code>，首先在 <code>import</code> 内引入 Alert 组件：</p> <pre><code class="chroma language-diff"><span class="gd">- import { ConfigProvider, DatePicker, message } from 'antd'; </span><span class="gd"></span><span class="gi">+ import { ConfigProvider, DatePicker, message, Alert } from 'antd'; </span></code></pre><p>然后在 <code>render</code> 内添加相应的 jsx 代码：</p> <pre><code class="chroma language-diff"> <DatePicker onChange={value => this.handleChange(value)} /> <div style={{ marginTop: 16 }}> <span class="gd">- 当前日期：{date ? date.format('YYYY-MM-DD') : '未选择'} </span><span class="gd"></span><span class="gi">+ <Alert message="当前日期" description={date ? date.format('YYYY年MM月DD日') : '未选择'} /> </span><span class="gi"></span> </div> </code></pre><p>选择一个日期，在右侧预览区就可以看到如图的效果。</p> <p><img width="420"

bug，也推荐建一个可重现的 codesandbox 来报告 bug。</p> <h3 id="user-content-4-下一步">4. 下一步</h3> <p>实际项目开发中，你会需要构建、调试、代理、打包部署等一系列工程化的需求。您可以阅读后面的文档或者使用以下脚手架和范例：</p> <ul> <li><a href="http://pro.ant.design/">Ant Design Pro</a></li> <li><a href="https://github.com/zuiidea/antd-admin">antd-admin</a></li> <li><a href="https://github.com/d2-projects/d2-admin">d2-admin</a></li> <li><a

<p><code>antd</code> 默认支持基于 ES modules 的 tree shaking，直接引入 <code>import { Button } from 'antd';</code> 就会有按需加载的效果。</p> <h2 id="user-content-自行构建">自行构建</h2> <p>如果想自己维护工作流，我们推荐使用 <a href="https://webpack.github.io/">webpack</a> 进行构建和调试，可以使用 React 生态圈中的 <a href="https://github.com/enaqx/awesome-react#react-tools">各种脚手架</a> 进行开发。</p> <p>目前社区也有很多基于 antd 定制的 <a href="http://scaffold.ant.design/">React 脚手架</a>，欢迎进行试用和贡献。</p>
