Nested Sites

Stacklane sites may be organized into smaller sub-sites and mounted at a path.

To nest a site at a sub-path of another site, create a configuration file such as: /🔌path-name.yaml where "path-name" will become the directory where the site is nested at. For example, if your main site is hosted at https://abccompany.com/, a configured nested site /🔌store.yaml would host the nested site at https://abccompany.com/store/

Base URLs

Development of a nested site should be no different than if the site is intended for deployment on a root domain. The final deployment location of the site (root domain or nested path) is code agnostic. Therefore the nested site's code should not hardcode its final mount location. Stacklane applies a few simple rules to facilitate this. The following scenarios are automatically modified to include the mount path prefix of the nested site:

  • Static assets such as links to scripts / images.
  • Redirects from JavaScript endpoints.
  • Form actions beginning with / — <form ... action="/my-endpoint">
  • Any HTML attribute in the format href="/my/path" where the attribute ends with href and its value begins with /.

The last rule covers a variety of scenarios including a, as well as custom attributes, for example:

data-custom-value-href="/the/path"

Another approach for client side JavaScript is to specify a base in <html> or <body>, such as this:

<html data-base-href="/">

If the site is deployed to the root domain then this will always be /.

Otherwise it will be the mount path where parent site is nesting this site.

Permissions

For production deployment, the repository /owner/ must match the owner of the source which is importing the nested site.

source

The only required field for a site mount is the location to obtain the nested site's source code.

source: https://github.com/owner/project.git

Optionally the source URL may specify a branch or tag.

namespace

Changing the namespace identifier after it contains production data will result in a loss of data.

If the nested site is data driven, then it must be assigned a data namespace. This ensures the data remains relevant if you later change its path. Minimum length is 4 characters, maximum length is 25 characters.

namespace: my-namespace

🎨

If the nested site contains a properties file, then the values in this file may be overridden, where the values beneath "🎨" correspond to values in the nested site's 🎨.scss properties file.

🎨:
  some-option: true
  the-color: aliceblue

A nested site definition may also use properties from the parent:

🎨:
  the-color: $name-of-parent-property

keys

Since secure keys and credentials are scoped to the parent, there may be certain keys that the parent needs to expose to a nested site. The parent must explicitly specify individual keys, and any other keys will be non-existent for the nested site.
