vuepress搭建带有移动端展示的文档

VuePress 是一个以 Markdown 为中心的静态网站生成器。你可以使用 Markdown 来书写内容(如文档、博客等),然后 VuePress 会帮助你生成一个静态网站来展示它们。

本文是使用 vuepress 搭建类似于 vant 文档,右侧带有移动端展示。先看下成果:shop-m使用文档 ,左侧是文档,右侧带有移动端展示,且会根据不同的文档页面,移动端跳转到对应的页面展示。

VuePress自定义

VuePress 提供的默认主题就挺好的,我们使用 布局插槽 来完成我们的功能。

默认主题的 Layout 布局提供了一些插槽:

  1. navbar
  2. navbar-before
  3. navbar-after
  4. sidebar
  5. sidebar-top
  6. sidebar-bottom
  7. page
  8. page-top
  9. page-bottom
  10. page-content-top
  11. page-content-bottom

在它们的帮助下,你可以很容易地添加或替换内容。下面通过一个示例来介绍一下如何使用布局插槽来继承默认主题。

首先,创建你的本地主题 docs/.vuepress/theme/index.js :

const { defaultTheme } = require('vuepress')
const { path } = require('@vuepress/utils')

module.exports = {
  localTheme: (options) => {
    return {
      name: 'vuepress-theme-local',
      extends: defaultTheme(options),
      layouts: {
        Layout: path.resolve(__dirname, 'layouts/Layout.vue'),
      },
    }
  }
}

这样你的本地主题将会继承默认主题,并且覆盖 Layout 布局。

接下来,创建 docs/.vuepress/theme/layouts/Layout.vue ,并使用由默认主题的 Layout 布局提供的插槽:

<script setup>
import { watch, ref, nextTick } from 'vue'
import ParentLayout from '@vuepress/theme-default/lib/client/layouts/Layout.vue'
import { useRouter, useRoute } from 'vue-router'
import pathList from './../pathList.js'

const route = useRoute()
const iframeId = ref(null)
const iframeBaseUrl = import.meta.env.MODE === 'development' ? 'http://localhost:3000/shop-m/#' : 'https://shop-template.github.io/shop-m/#'
const iframeUrl = ref(iframeBaseUrl)

// 根据父 path 拿到 子 path
function parentPathToChildrenPath(parentPath) {
  const cur = pathList.find(x => x.parentPath === parentPath)
  return cur ? cur.childrenPath : ''
}

// 首次设置 iframe 的链接
iframeUrl.value = `${iframeBaseUrl}${parentPathToChildrenPath(route.path)}`

let osEnd = ref('pc')
// 获取是移动端还是PC,摘自:https://tim.qq.com/
const OS = function() {
  var a = navigator.userAgent,
      b = /(?:Android)/.test(a),
      d = /(?:Firefox)/.test(a),
      e = /(?:Mobile)/.test(a),
      f = b && e,
      g = b && !f,
      c = /(?:iPad.*OS)/.test(a),
      h = !c && /(?:iPhone\sOS)/.test(a),
      k = c || g || /(?:PlayBook)/.test(a) || d && /(?:Tablet)/.test(a),
      a = !k && (b || h || /(?:(webOS|hpwOS)[\s\/]|BlackBerry.*Version\/|BB10.*Version\/|CriOS\/)/.test(a) || d && e);
  return {
      android: b,
      androidPad: g,
      androidPhone: f,
      ipad: c,
      iphone: h,
      tablet: k,
      phone: a
  }
}();
if (OS.phone || OS.ipad) {
  osEnd.value = 'phone'
}
let oldPath = route.path
watch(
  route,
  async (val) => {
    await nextTick()
    if (val.path !== oldPath) {
      oldPath = val.path
      const childrenPath = parentPathToChildrenPath(val.path)
      if (childrenPath) {
        if (osEnd.value === 'pc') {
          iframeId.value && iframeId.value.contentWindow.location.replace(`${iframeBaseUrl}${childrenPath}`)
        } else {
          iframeUrl.value = `${iframeBaseUrl}${childrenPath}`
        }
      }
    }
  },
  {
    deep: true,
    immediate: true
  }
)

  <ParentLayout>

文档页面的路由和移动端展示页面的路由关系配置在pathList.js文件中,一一对应关系:

// 配置父子 path
export default [
  {
    parentPath: '/guide/',
    childrenPath: '/'
  },
  {
    parentPath: '/guide/getting-started.html',
    childrenPath: '/'
  },
  {
    parentPath: '/guide/cssVar.html',
    childrenPath: '/demo/cssVar'
  },
  {
    parentPath: '/guide/navBar.html',
    childrenPath: '/demo/navBar'
  },
  {
    parentPath: '/guide/tabbar.html',
    childrenPath: '/demo/tabbar'
  },
  {
    parentPath: '/guide/network.html',
    childrenPath: '/demo/network'
  },
  {
    parentPath: '/guide/vconsole.html',
    childrenPath: '/demo/vconsole'
  },
  {
    parentPath: '/guide/404.html',
    childrenPath: '/aaaa'
  },
  {
    parentPath: '/guide/permission.html',
    childrenPath: '/user'
  },
  {
    parentPath: '/guide/login.html',
    childrenPath: '/login'
  },
  {
    parentPath: '/guide/userInfo.html',
    childrenPath: '/userInfo'
  },
  {
    parentPath: '/plugins/compressorjs.html',
    childrenPath: '/userInfo'
  }
]

其中需要注意的是 iframe 的链接赋值之后不能再次赋值,否则会在 history 中增加一个记录,导致浏览器点击返回按钮出问题,解决方案如下:

iframeId.value && iframeId.value.contentWindow.location.replace(`${iframeBaseUrl}${childrenPath}`)

PC端中移动端展示放在 navbar-after 插槽内,是为了防止每次路由变更之后 iframe 都重新创建的问题。移动端中移动端展示放在 page-content-bottom 插槽内,因为其他位置的插槽会导致摆放位置不太符合。所以针对PC端、移动端做不同的逻辑处理:

let osEnd = ref('pc')
// 获取是移动端还是PC,摘自:https://tim.qq.com/
const OS = function() {
  var a = navigator.userAgent,
      b = /(?:Android)/.test(a),
      d = /(?:Firefox)/.test(a),
      e = /(?:Mobile)/.test(a),
      f = b && e,
      g = b && !f,
      c = /(?:iPad.*OS)/.test(a),
      h = !c && /(?:iPhone\sOS)/.test(a),
      k = c || g || /(?:PlayBook)/.test(a) || d && /(?:Tablet)/.test(a),
      a = !k && (b || h || /(?:(webOS|hpwOS)[\s\/]|BlackBerry.*Version\/|BB10.*Version\/|CriOS\/)/.test(a) || d && e);
  return {
      android: b,
      androidPad: g,
      androidPhone: f,
      ipad: c,
      iphone: h,
      tablet: k,
      phone: a
  }
}();
if (OS.phone || OS.ipad) {
  osEnd.value = 'phone'
}

观测路由变化,让移动端展示显示不同的路径页面:

// 根据父 path 拿到 子 path
function parentPathToChildrenPath(parentPath) {
  const cur = pathList.find(x => x.parentPath === parentPath)
  return cur ? cur.childrenPath : ''
}
...
watch(
  route,
  async (val) => {
    await nextTick()
    if (val.path !== oldPath) {
      oldPath = val.path
      const childrenPath = parentPathToChildrenPath(val.path)
      if (childrenPath) {
        if (osEnd.value === 'pc') {
          iframeId.value && iframeId.value.contentWindow.location.replace(`${iframeBaseUrl}${childrenPath}`)
        } else {
          iframeUrl.value = `${iframeBaseUrl}${childrenPath}`
        }
      }
    }
  },
  {
    deep: true,
    immediate: true
  }
)

注意:iframe 链接是全连接,所以需要自行修改 docs/.vuepress/theme/layouts/Layout.vue 中的 iframeBaseUrl 变量。

至此就可以实现一个带移动端展示的 shop-m使用文档 。
