给VitePress的右上角增加Github角标

介绍

我没有找到VitePress的Github角标的插件，所以做了后面的嵌入流程，方案是在主题布局中直接引入。如果不知道这两个项目的同学可以看看介绍部分

github-corner

可以在页面的四角显示Github角标，可以自定义大小、背景颜色。当鼠标移动到这个角标时还能看到Github摇尾巴的动画

VitePress

VitePress 是一个静态站点生成器 (SSG)，专为构建快速、以内容为中心的站点而设计。简而言之，VitePress 获取用 Markdown 编写的内容，对其应用主题，并生成可以轻松部署到任何地方的静态 HTML 页面。

具体流程

1. 创建自定义主题组件

在 .vitepress/theme 目录下创建组件：

# 创建主题目录结构
mkdir -p .vitepress/theme/components
touch .vitepress/theme/index.js
touch .vitepress/theme/components/GitHubCorner.vue

2. 创建 GitHub Corner 组件

.vitepress/theme/components/GitHubCorner.vue：

<template>
    <a
        :href="repoUrl"
        class="github-corner"
        aria-label="View source on GitHub"
        target="_blank"
        rel="noopener noreferrer"
    >
        <svg
            width="80"
            height="80"
            viewBox="0 0 250 250"
            style="fill:#151513; color:#fff; position: fixed; top: 0; border: 0; right: 0; z-index: 1000;"
            aria-hidden="true"
        >
            <path d="M0,0 L115,115 L130,115 L142,142 L250,250 L250,0 Z"></path>
            <path
                d="M128.3,109.0 C113.8,99.7 119.0,89.6 119.0,89.6 C122.0,82.7 120.5,78.6 120.5,78.6 C119.2,72.0 123.4,76.3 123.4,76.3 C127.3,80.9 125.5,87.3 125.5,87.3 C122.9,97.6 130.6,101.9 134.4,103.2"
                fill="currentColor"
                style="transform-origin: 130px 106px;"
                class="octo-arm"
            ></path>
            <path
                d="M115.0,115.0 C114.9,115.1 118.7,116.5 119.8,115.4 L133.7,101.6 C136.9,99.2 139.9,98.4 142.2,98.6 C133.8,88.0 127.5,74.4 143.8,58.0 C148.5,53.4 154.0,51.2 159.7,51.0 C160.3,49.4 163.2,43.6 171.4,40.1 C171.4,40.1 176.1,42.5 178.8,56.2 C183.1,58.6 187.2,61.8 190.9,65.4 C194.5,69.0 197.7,73.2 200.1,77.6 C213.8,80.2 216.3,84.9 216.3,84.9 C212.7,93.1 206.9,96.0 205.4,96.6 C205.1,102.4 203.0,107.8 198.3,112.5 C181.9,128.9 168.3,122.5 157.7,114.1 C157.9,116.9 156.7,120.9 152.7,124.9 L141.0,136.5 C139.8,137.7 141.6,141.9 141.8,141.8 Z"
                fill="currentColor"
                class="octo-body"
            ></path>
        </svg>
    </a>
</template>

<script>
export default {
    name: 'GitHubCorner',
    props: {
        repoUrl: {
            type: String,
            required: true
        }
    }
}
</script>

<style scoped>
.github-corner:hover .octo-arm {
    animation: octocat-wave 560ms ease-in-out;
}

@keyframes octocat-wave {
    0%,
    100% {
        transform: rotate(0);
    }
    20%,
    60% {
        transform: rotate(-25deg);
    }
    40%,
    80% {
        transform: rotate(10deg);
    }
}

@media (max-width: 500px) {
    .github-corner:hover .octo-arm {
        animation: none;
    }
    .github-corner .octo-arm {
        animation: octocat-wave 560ms ease-in-out;
    }

    /* 在移动端可以调整大小 */
    .github-corner svg {
        width: 60px;
        height: 60px;
    }
}
</style>

3. 修改 .vitepress/theme/index.js

// https://vitepress.dev/guide/custom-theme
import { h } from 'vue'
import DefaultTheme from 'vitepress/theme'
import './style.css'
import GitHubCorner from './components/GitHubCorner.vue'

/** @type {import('vitepress').Theme} */
export default {
    extends: DefaultTheme,
    Layout: () => {
        return h(DefaultTheme.Layout, null, {
            // 在 layout-top 插槽中添加 GitHub Corner
            'layout-top': () => h(GitHubCorner, {
                repoUrl: 'https://github.com/baby7/agile-tiles'
            })
        })
    },
    enhanceApp({ app, router, siteData }) {
        // 如果需要，也可以在这里注册为全局组件
        // app.component('GitHubCorner', GitHubCorner)
    }
}
