Redirects allow you to redirect an incoming request path to a different destination path.

Redirects are only available on the Node.js environment and do not affect client-side routing.

To use Redirects you can use the redirects key in next.config.js:

module.exports = {
  async redirects() {
    return [
      {
        source: '/about',
        destination: '/',
        permanent: true,
      },
    ]
  },
}

redirects is an async function that expects an array to be returned holding objects with source, destination, and permanent properties:

  • source is the incoming request path pattern.
  • destination is the path you want to route to.
  • permanent if the redirect is permanent or not.
  • basePath: false or undefined - if false the basePath won't be included when matching, can be used for external rewrites only.
  • locale: false or undefined - whether the locale should not be included when matching.
  • has is an array of has objects with the type, key and value properties.

Redirects are checked before the filesystem which includes pages and /public files.

Path Matching

Path matches are allowed, for example /old-blog/:slug will match /old-blog/hello-world (no nested paths):

module.exports = {
  async redirects() {
    return [
      {
        source: '/old-blog/:slug',
        destination: '/news/:slug', // Matched parameters can be used in the destination
        permanent: true,
      },
    ]
  },
}

Wildcard Path Matching

To match a wildcard path you can use * after a parameter, for example /blog/:slug* will match /blog/a/b/c/d/hello-world:

module.exports = {
  async redirects() {
    return [
      {
        source: '/blog/:slug*',
        destination: '/news/:slug*', // Matched parameters can be used in the destination
        permanent: true,
      },
    ]
  },
}

Regex Path Matching

To match a regex path you can wrap the regex in parentheses after a parameter, for example /post/:slug(\\d{1,}) will match /post/123 but not /post/abc:

module.exports = {
  async redirects() {
    return [
      {
        source: '/post/:slug(\\d{1,})',
        destination: '/news/:slug', // Matched parameters can be used in the destination
        permanent: false,
      },
    ]
  },
}

The following characters (, ), {, }, :, *, +, ? are used for regex path matching, so when used in the source as non-special values they must be escaped by adding \\ before them:

module.exports = {
  async redirects() {
    return [
      {
        // this will match `/english(default)/something` being requested
        source: '/english\\(default\\)/:slug',
        destination: '/en-us/:slug',
        permanent: false,
      },
    ]
  },
}

Header, Cookie, and Query Matching

To only match a redirect when header, cookie, or query values also match the has field can be used. Both the source and all has items must match for the redirect to be applied.

has items have the following fields:

  • type: String - must be either header, cookie, host, or query.
  • key: String - the key from the selected type to match against.
  • value: String or undefined - the value to check for, if undefined any value will match. A regex like string can be used to capture a specific part of the value, e.g. if the value first-(?<paramName>.*) is used for first-second then second will be usable in the destination with :paramName.
module.exports = {
  async redirects() {
    return [
      // if the header `x-redirect-me` is present,
      // this redirect will be applied
      {
        source: '/:path((?!another-page$).*)',
        has: [
          {
            type: 'header',
            key: 'x-redirect-me',
          },
        ],
        permanent: false,
        destination: '/another-page',
      },
      // if the source, query, and cookie are matched,
      // this redirect will be applied
      {
        source: '/specific/:path*',
        has: [
          {
            type: 'query',
            key: 'page',
            // the page value will not be available in the
            // destination since value is provided and doesn't
            // use a named capture group e.g. (?<page>home)
            value: 'home',
          },
          {
            type: 'cookie',
            key: 'authorized',
            value: 'true',
          },
        ],
        permanent: false,
        destination: '/another/:path*',
      },
      // if the header `x-authorized` is present and
      // contains a matching value, this redirect will be applied
      {
        source: '/',
        has: [
          {
            type: 'header',
            key: 'x-authorized',
            value: '(?<authorized>yes|true)',
          },
        ],
        permanent: false,
        destination: '/home?authorized=:authorized',
      },
      // if the host is `example.com`,
      // this redirect will be applied
      {
        source: '/:path((?!another-page$).*)',,
        has: [
          {
            type: 'host',
            value: 'example.com',
          },
        ],
        destination: '/another-page',
      },
    ]
  },
}

Redirects with basePath support

When leveraging basePath support with redirects each source and destination is automatically prefixed with the basePath unless you add basePath: false to the redirect:

module.exports = {
  basePath: '/docs',

  async redirects() {
    return [
      {
        source: '/with-basePath', // automatically becomes /docs/with-basePath
        destination: '/another', // automatically becomes /docs/another
        permanent: false,
      },
      {
        // does not add /docs since basePath: false is set
        source: '/without-basePath',
        destination: '/another',
        basePath: false,
        permanent: false,
      },
    ]
  },
}

Redirects with i18n support

When leveraging i18n support with redirects each source and destination is automatically prefixed to handle the configured locales unless you add locale: false to the redirect. If locale: false is used you must prefix the source and destination with a locale for it to be matched correctly.

module.exports = {
  i18n: {
    locales: ['en', 'fr', 'de'],
    defaultLocale: 'en',
  },

  async redirects() {
    return [
      {
        source: '/with-locale', // automatically handles all locales
        destination: '/another', // automatically passes the locale on
        permanent: false,
      },
      {
        // does not handle locales automatically since locale: false is set
        source: '/nl/with-locale-manual',
        destination: '/nl/another',
        locale: false,
        permanent: false,
      },
      {
        // this matches '/' since `en` is the defaultLocale
        source: '/en',
        destination: '/en/another',
        locale: false,
        permanent: false,
      },
      {
        // this gets converted to /(en|fr|de)/(.*) so will not match the top-level
        // `/` or `/fr` routes like /:path* would
        source: '/(.*)',
        destination: '/another',
        permanent: false,
      },
    ]
  },
}

In some rare cases, you might need to assign a custom status code for older HTTP Clients to properly redirect. In these cases, you can use the statusCode property instead of the permanent property, but not both. Note: to ensure IE11 compatibility a Refresh header is automatically added for the 308 status code.
