4.0.0.alpha1

Almost six years after releasing v1.0.0, we're proud to ship the first alpha release of ViewComponent 4. This release marks a shift towards a Long Term Support model for the project, having reached significant feature maturity. While contributions are always welcome, we're unlikely to accept further breaking changes or major feature additions.

Please test this release and report any issues to this repository.

• BREAKING: --inline generator option now generates inline template. Use --call to generate #call method.

  Joel Hawksley

• BREAKING: Remove use_deprecated_instrumentation_name configuration option. Events will always use render.view_component name.

  Joel Hawksley

• BREAKING: Remove preview_source functionality. Consider using Lookbook instead.

  Joel Hawksley

• BREAKING: Use Nokogiri::HTML5 instead of Nokogiri::HTML4 for test helpers.

  Noah Silvera, Joel Hawksley

• BREAKING: Move generators to a ViewComponent namespace.

  Before, ViewComponent generators pollute the generator namespace with a bunch of top level items, and claim the generic "component" name.

  Now, generators live in a "view_component" module/namespace, so what was before rails g component is now rails g view_component:component.

  Paul Sadauskas

  Joel Hawksley

• BREAKING: Remove support for variant names containing . to be consistent with Rails.

  Stephen Nelson

• BREAKING: Use ActionView's lookup_context for picking templates instead of the request format.

  3.15 added support for using templates that match the request format, i.e. if /resource.csv is requested then
  ViewComponents would pick _component.csv.erb over _component.html.erb.

  With this release, the request format is no longer considered and instead ViewComponent will use the Rails logic
  for picking the most appropriate template type, i.e. the csv template will be used if it matches the Accept header
  or because the controller uses a respond_to block to pick the response format.

  Stephen Nelson

• BREAKING: Rename internal methods to have __vc_ prefix if they shouldn't be used by consumers. Make internal constants private. Make Collection#components, Slotable#register_polymorphic_slot private. Remove unused ComponentError class.
