[0.6.1] - 2026-06-11

Fixed

  • Load the ViewComponent component generator hook only when Rails generators are loaded, preventing app boot failures.

[0.6.0] - 2026-06-07

Added

  • config.view_component.generate.stylesheet = true to auto-generate a sidecar-compatible .css file when running view_component:component, inject include ViewComponent::ScopedStyles, and add component_class to the generated ERB template.
  • component_class(..., from: OtherComponent) to reference scoped classes from another component in templates.
  • :component(OtherComponent[, class_name]) compile-time CSS references for sidecar stylesheets and styles blocks, including use inside selector functions like :where() and :has().

Fixed

  • Require ActiveSupport's enumerable extensions explicitly so scoped class map generation has index_with available outside Rails load paths.

[0.5.0] - 2026-06-01

Breaking changes

This release is incompatible with 0.4.x. Scoped class names and compiled CSS selectors change unless you opt into the previous behaviour.

  • Default css_class_prefix is now "{class_name}_" instead of "c-". For example, .component becomes .component_a1b2c3d4 rather than .c-a1b2c3d4.
  • css_class_prefix is a template string supporting {class_name} and {component_name} (namespaces joined by /). Per-component css_class_prefix uses the same interpolation.
  • Forward slashes in interpolated class names are escaped in compiled CSS selectors (e.g. Admin/UserCardComponent → Admin\/UserCardComponent).

Upgrade from 0.4.x: set config.css_class_prefix = "c-" in your initializer (and per-component overrides if any) to keep existing class names, then regenerate components.scoped.css in development. Otherwise update templates and markup to match the new scoped class names.

Added

  • ViewComponent::ScopedStyles::CssClassPrefix for prefix interpolation and CSS selector escaping.

[0.4.1] - 2026-06-01

Fixed

  • Railtie component discovery now respects the configured components_path instead of always scanning app/components.

[0.4.0] - 2026-05-31

Added

  • assets_path and stylesheet_name global configuration options to customize where the bundled scoped stylesheet is written (defaults: app/assets/stylesheets and components.scoped.css).

[0.3.0] - 2026-05-29

Added

  • css_class_prefix global configuration option and per-component css_class_prefix method to customize the prefix for scoped class names (default: "c-").

[0.2.0] - 2026-05-29

Added

  • ignored_css_classes to keep specific selectors unscoped in generated CSS; component_class("name") returns the original class name for ignored classes.

Changed

  • Style registration and writes to components.scoped.css run only in development; production and test use the committed stylesheet.

Fixed

  • Require digest explicitly and qualify Digest::MD5 so scoped class IDs generate correctly in test and other load orders.
  • Railtie development reload uses an initializer so to_prepare runs after Rails is fully loaded.

[0.1.0] - 2026-05-28

  • Initial release
