📦 plugin-client-redirects

Docusaurus Plugin to generate client-side redirects.

这个插件会在你的静态网站中写入额外的 HTML 页面，通过 JavaScript 将用户重定向到已有的 Docusaurus 页面。

production only

This plugin is always inactive in development and only active in production because it works on the build output.

警告

如果可行，你最好用服务端重定向。

在用这个插件前，你应该确定你的托管商是否确实不提供此功能。

Installation

npm

npm install --save @docusaurus/plugin-client-redirects

Yarn

yarn add @docusaurus/plugin-client-redirects

pnpm

pnpm add @docusaurus/plugin-client-redirects

Configuration

接受的字段：

选项	类型	默认值	描述
fromExtensions	string[]	[]	重定向后从路径中去除的扩展名。
toExtensions	string[]	[]	重定向后添加到路径中的扩展名。
redirects	RedirectRule[]	[]	重定向规则列表。
createRedirects	CreateRedirectsFn	undefined	用于创建重定向规则的回调。 Docusaurus 会用每一个它创建的路径来调用这个回调，然后用它的返回值来输出更多路径。

备注

This plugin will also read the siteConfig.onDuplicateRoutes config to adjust its logging level when multiple files will be emitted to the same location.

Types

RedirectRule

type RedirectRule = {
  to: string;
  from: string | string[];
};

备注

"From" 和 "to" 的概念是这个插件的核心。 "From" means a path that you want to create, i.e. an extra HTML file that will be written; "to" means a path to want to redirect to, usually a route that Docusaurus already knows about.

这就是为什么你可以对于同一个 "to" 有多个 "from"：我们会创建多个 HTML 文件，它们全部重定向到同一个目标。 另一方面，一个 "from" 永远不会有多于一个 "to"：写入的 HTML 文件必须有唯一确定的目标。

CreateRedirectsFn

// The parameter `path` is a route that Docusaurus has already created. It can
// be seen as the "to", and your return value is the "from". Returning a falsy
// value will not create any redirect pages for this particular path.
type CreateRedirectsFn = (path: string) => string[] | string | null | undefined;

Example configuration

这是一个示例配置：

docusaurus.config.js

export default {
  plugins: [
    [
      '@docusaurus/plugin-client-redirects',
      {
        fromExtensions: ['html', 'htm'], // /myPage.html -> /myPage
        toExtensions: ['exe', 'zip'], // /myAsset -> /myAsset.zip (if latter exists)
        redirects: [
          // /docs/oldDoc -> /docs/newDoc
          {
            to: '/docs/newDoc',
            from: '/docs/oldDoc',
          },
          // Redirect from multiple old paths to the new path
          {
            to: '/docs/newDoc2',
            from: ['/docs/oldDocFrom2019', '/docs/legacyDocFrom2016'],
          },
        ],
        createRedirects(existingPath) {
          if (existingPath.includes('/community')) {
            // Redirect from /docs/team/X to /community/X and /docs/support/X to /community/X
            return [
              existingPath.replace('/community', '/docs/team'),
              existingPath.replace('/community', '/docs/support'),
            ];
          }
          return undefined; // Return a falsy value: no redirect created
        },
      },
    ],
  ],
};
