<h1 id="前言"><a class="markdownIt-Anchor" href="#前言"></a> 前言</h1>
<p>作为一名常用 Material-UI 的开发者，我经常需要将各种 SVG 图标集成到项目中。虽然 Material-UI 本身提供了丰富的图标库，但很多时候我们还是会遇到需要自定义图标的情况。例如在网站的落地页上加一个大大的 logo，把它设置成五彩斑斓的黑色……</p>
<p>过去要这么做，得手动封装 SVG、将其转换为 React 组件。这么搞很浪费时间，我因此萌生出将其自动化的想法、写了 <code>Svg2SvgIcon</code>。</p>
<h1 id="svg2svgicon"><a class="markdownIt-Anchor" href="#svg2svgicon"></a> <code>Svg2SvgIcon</code></h1>
<p><code>Svg2SvgIcon</code> 是一个纯客户端的在线转换工具，它可以将任意 SVG 代码或文件、快速转换为可以直接在你的 React 项目中使用的 Material-UI <code>SvgIcon</code> 组件。</p>
<p><a target="_blank" rel="noopener" href="https://github.com/Cytrogen/SVG2SvgIcon"><img src="https://gh-card.dev/repos/Cytrogen/SVG2SvgIcon.svg" alt="Cytrogen/SVG2SvgIcon - GitHub"></a></p>
<p><a href="%5Bhttps://%5D(https://svg2svgicon.cytrogen.icu/)">点击这里传送</a>。</p>
<blockquote>
<p>或者自行复制到浏览器内：</p>
<figure class="highlight plaintext"><table><tbody><tr><td class="gutter"><pre><span class="line">1</span><br></pre></td><td class="code"><pre><span class="line">https://svg2svgicon.cytrogen.icu/</span><br></pre></td></tr></tbody></table></figure>
</blockquote>
<h2 id="核心功能"><a class="markdownIt-Anchor" href="#核心功能"></a> 核心功能</h2>
<p>该工具的核心设计理念是高效、易用和安全。纯客户端意味着你上传或粘贴的任何 SVG 数据都只会在你的浏览器中进行处理、不会发送到任何服务器，最大限度地保障了你的隐私和数据安全。</p>
<p>以下是 <code>Svg2SvgIcon</code> 的主要功能：</p>
<ul>
<li>智能的 <code>viewBox</code> 解析：
<ul>
<li>自动读取 SVG 中已有的 <code>viewBox</code> 属性</li>
<li>若 <code>viewBox</code> 不存在，会使用 SVG 的 <code>width</code> 和 <code>height</code> 属性来生成</li>
<li>若以上全无，则默认使用 <code>0 0 24 24</code>，确保图标能正确显示</li>
</ul>
</li>
<li>实时预览与控制器：
<ul>
<li>在输入或修改 SVG 后，你可以立即在预览窗口中看到转换后的图标效果</li>
<li>提供实时控制器，方便你精确调整 <code>viewBox</code> 的 <code>min-x</code>、<code>min-y</code>、<code>width</code> 和 <code>height</code> 值，所有调整都会立刻反映在预览图标上</li>
<li>提供「重置」按钮，一键恢复到原始的 <code>viewBox</code> 值</li>
</ul>
</li>
<li>全面的 SVG 解析能力：
<ul>
<li>支持解析嵌套元素，例如 <code><g></code> 标签</li>
<li>正确处理并转换行内的 <code>style</code> 属性为 React 的 <code>style</code> 对象</li>
</ul>
</li>
<li>内置错误控制台：
<ul>
<li>内置一个可抽拉的错误控制台，当发生解析错误时会自动滑出提示</li>
<li>右下角的浮动按钮会用红点标记未读错误，方便你随时查看</li>
</ul>
</li>
<li>一键复制
<ul>
<li>自动生成可以直接在项目中使用的 React 组件代码，并提供「一键复制」功能</li>
</ul>
</li>
</ul>
<h2 id="如何使用"><a class="markdownIt-Anchor" href="#如何使用"></a> 如何使用</h2>
<p>使用 <code>Svg2SvgIcon</code> 非常简单，只需几步：</p>
<ol>
<li>输入 SVG 或者上传一个 <code>.svg</code> 文件</li>
<li>为即将生成的 React 组件起一个合适的名称</li>
<li>点击「转换 SVG」按钮，右侧会立刻显示图标预览和生成的代码</li>
<li>（可选）调整 <code>viewBox</code></li>
<li>点击「复制代码」按钮，然后将代码粘贴到你的 React 项目中即可使用</li>
</ol>
<p><img src="/posts/369e/image.png" alt="alt text"></p>
<h2 id="技术栈与开源"><a class="markdownIt-Anchor" href="#技术栈与开源"></a> 技术栈与开源</h2>
<p><code>Svg2SvgIcon</code> 的核心技术栈非常精简：</p>
<ul>
<li>React</li>
<li>Material-UI</li>
<li>DOMParser</li>
</ul>
<p>这个项目已在 GitHub 上开源，并采用 MIT 许可证。</p>
