📦 plugin-client-redirects

Docusaurus Plugin to generate client-side redirects.

This plugin will write additional HTML pages to your static site that redirect the user to your existing Docusaurus pages with JavaScript.

production only

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

caution

It is better to use server-side redirects whenever possible.

Before using this plugin, you should look if your hosting provider doesn't offer this feature.

Installation

npm

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

Yarn

yarn add @docusaurus/plugin-client-redirects

Configuration

Accepted fields:

Option	Type	Default	Description
fromExtensions	string[]	[]	The extensions to be removed from the route after redirecting.
toExtensions	string[]	[]	The extensions to be appended to the route after redirecting.
redirects	RedirectRule[]	[]	The list of redirect rules.
createRedirects	CreateRedirectsFn	undefined	A callback to create a redirect rule. Docusaurus query this callback against every path it has created, and use its return value to output more paths.

note

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[];
};

note

The idea of "from" and "to" is central in this plugin. "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.

This is why you can have multiple "from" for the same "to": we will create multiple HTML files that all redirect to the same destination. On the other hand, one "from" can never have more than one "to": the written HTML file needs to have a determinate destination.

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

Here's an example configuration:

docusaurus.config.js

module.exports = {
  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
        },
      },
    ],
  ],
};
