    gatsby-plugin-gatsby-cloud

    Automatically generates a _headers.json file and a _redirects.json file at the root of the public folder to configure Headers and Redirects on Gatsby Cloud.

    By default, the plugin will add some basic security headers. You can easily add or replace headers through the plugin config.

    NOTE: This plugin is autoinstalled on Gatsby Cloud to ensure the latest compatible version, there is no need to install it locally unless you wish to add plugin config.

    Install

    npm install --save gatsby-plugin-gatsby-cloud

    How to use

    // In your gatsby-config.js
    plugins: [`gatsby-plugin-gatsby-cloud`]

    Configuration

    If you just need the critical assets, you don't need to add any additional config. However, if you want to add headers, remove default headers, or transform the given headers, you can use the following configuration options.

    plugins: [
      {
        resolve: `gatsby-plugin-gatsby-cloud`,
        options: {
          headers: {}, // option to add more headers. `Link` headers are transformed by the below criteria
          allPageHeaders: [], // option to add headers for all pages. `Link` headers are transformed by the below criteria
          mergeSecurityHeaders: true, // boolean to turn off the default security headers
          mergeLinkHeaders: true, // boolean to turn off the default gatsby js headers
          mergeCachingHeaders: true, // boolean to turn off the default caching headers
          transformHeaders: (headers, path) => headers, // optional transform for manipulating headers under each path (e.g.sorting), etc.
          generateMatchPathRewrites: true, // boolean to turn off automatic creation of redirect rules for client only paths
        },
      },
    ]

    Headers

    You should pass in an object with string keys (representing the paths) and an array of strings for each header.

    An example:

    {
      options: {
        headers: {
          "/*": [
            "Basic-Auth: someuser:somepassword anotheruser:anotherpassword",
          ],
          "/my-page": [
            // matching headers (by type) are replaced by Gatsby Cloud with more specific routes
            "Basic-Auth: differentuser:differentpassword",
          ],
        },
      }
    }

    Link paths are specially handled by this plugin. Since most files are processed and cache-busted through Gatsby (with a file hash), the plugin will transform any base file names to the hashed variants. If the file is not hashed, it will ensure the path is valid relative to the output public folder. You should be able to reference assets imported through javascript in the static folder.

    Do not specify the public path in the config, as the plugin will provide it for you.

    The _headers.json file does not inherit headers, and it will replace any matching headers it finds in more specific routes. For example, if you add a link to the root wildcard path (/*), it will be replaced by any more specific path. If you want a resource to put linked across the site, you will have to add to every path. To make this easier, the plugin provides the allPageHeaders option to inject the same headers on every path.

    {
      options: {
        allPageHeaders: [
          "Link: </static/my-logo.png>; rel=preload; as=image",
        ],
        headers: {
          "/*": [
            "Basic-Auth: someuser:somepassword anotheruser:anotherpassword",
          ],
        },
      }
    }

    Redirects

    You can create redirects using the createRedirect action.

    In addition to the options provided by the Gatsby API, you can pass these options specific to this plugin:

    Attribute Description
    statusCode Overrides the HTTP status code which is set to 302 by default or 301 when isPermanent is true. You can set one here. For example, 200 for rewrites, or 404 for a custom error page.

    An example:

    createRedirect({ fromPath: "/old-url", toPath: "/new-url", isPermanent: true })
    createRedirect({ fromPath: "/url", toPath: "/zn-CH/url", Language: "zn" })
    createRedirect({
      fromPath: "/url_that_is/not_pretty",
      toPath: "/pretty/url",
      statusCode: 200,
    })
    createRedirect({
      fromPath: "/packages/*",
      toPath: "/plugins/*",
    })

    Redirect rules are automatically added for client only paths. The plugin uses the matchPath syntax to match all possible requests in the range of your client-side routes and serves the HTML file for the client-side route. Without it, only the exact route of the client-side route works.

    If those rules are conflicting with custom rules or if you want to have more control over them you can disable them in configuration by setting generateMatchPathRewrites to false.

    An asterisk, *, will match anything that follows. i.e. /packages/gatsby-plugin-gatsby-cloud/ will be redirected to /plugins/gatsby-plugin-gatsby-cloud/.

    HTTP Strict Transport Security

    HSTS Cheatsheet

    Since this header is an opt-in security enhancement with permanent consequences we don't include it as a default feature but use the allPagesHeaders to include it.

    {
      options: {
        allPageHeaders: [
          "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload",
        ],
      }
    }
