Module: ReactManifest::ViewHelpers

Defined in:
lib/react_manifest/view_helpers.rb

Overview

Provides the ‘react_bundle_tag` view helper, included in ActionView::Base.

Usage in layouts:

<%= react_bundle_tag defer: true %>

Resolves which ux_*.js bundles to include based on controller_path:

1. Always includes config.shared_bundle (e.g. "ux_shared")
2. Always appends config.always_include (e.g. ["ux_main"])
3. Appends "ux_<controller_path>" if that bundle file exists
4. For namespaced controllers (admin/users): checks ux_admin_users, then ux_admin
5. Returns "" for pure ERB/HAML pages with no matching bundle, or when
   called outside a controller context (mailers, engines, etc.)
