Static Assets Use Absolute URLs Instead of Relative URLs

[creepysta]

Summary

When hosting hub.getdbt.com behind a reverse proxy or in a custom environment, static assets (e.g., JS, CSS) are prefixed with the absolute static_url (e.g., https://hub.getdbt.com/image/...), causing broken references when the site is served from a different domain or path.

Problem

Currently, all static assets are referenced using a static_url prefix, which is hardcoded to be either:

• http://localhost:4567 (in dev)
• https://hub.getdbt.com (in prod)
  This approach causes problems when deploying the site behind a reverse proxy or on a custom domain (e.g., https://internal.myorg.com/dbt-hub), as the asset URLs still point to the original domain.

Suggested Fix

• Remove the hardcoded static_url prefix from asset links and instead:
• Use relative URLs in templates and static references
• Optionally allow configuring a base_path or asset_prefix if advanced customization is needed
  eg;

--- a/source/_nav.erb
+++ b/source/_nav.erb
-                       <img src='<%= site_url %>/img/logos/dbt-lockup.png' style="height: 48px"/>
+                       <img src='/img/logos/dbt-lockup.png' style="height: 48px"/>

or in config.rb -

set :host, ENV[''MM_HOST] || 'hub.getdbt.com'
set :base_prefix ENV['MM_BASE_PREFIX'] || "/"
... 
helpers do
  def host_with_port
    [[config[:host], config[:base_prefix]].compact.join("/"), optional_port].compact.join(':')
  end

  def optional_port
    config[:port] unless [80, 443].include? config[:port].to_i
  end

  def site_url
    config[:protocol] + host_with_port
  end
end
