Overview

Preview window URL configuration

By default Alchemy uses its internal page preview renderer, but you can configure it to be any URL instead.

Basic Auth is supported.

Example config/alchemy/config.yml

preview:
  host: https://www.my-static-site.com
  auth:
    username: <%= ENV["BASIC_AUTH_USERNAME"] %>
    password: <%= ENV["BASIC_AUTH_PASSWORD"] %>

Preview config per site is supported as well.

Example config/alchemy/config.yml

preview:
  My site name:
    host: https://www.my-static-site.com
    auth:
      username: <%= ENV["BASIC_AUTH_USERNAME"] %>
      password: <%= ENV["BASIC_AUTH_PASSWORD"] %>
