.generate ⇒ ActiveSupport::OrderedOptions

The subset of configuration options relating to generators.

All options under this namespace default to ‘false` unless otherwise stated.

#### ‘#path`

Where to put generated components. Defaults to ‘app/components`:

config.view_component.generate.path = "lib/components"

#### ‘#sidecar`

Always generate a component with a sidecar directory:

config.view_component.generate.sidecar = true

#### ‘#stimulus_controller`

Always generate a Stimulus controller alongside the component:

config.view_component.generate.stimulus_controller = true

#### ‘#typescript`

Generate TypeScript files instead of JavaScript files:

config.view_component.generate.typescript = true

#### ‘#locale`

Always generate translations file alongside the component:

config.view_component.generate.locale = true

#### ‘#distinct_locale_files`

Always generate as many translations files as available locales:

config.view_component.generate.distinct_locale_files = true

One file will be generated for each configured ‘I18n.available_locales`, falling back to `[:en]` when no `available_locales` is defined.

#### ‘#preview`

Always generate a preview alongside the component:

config.view_component.generate.preview = true

#### #preview_path

Path to generate preview:

config.view_component.generate.preview_path = "test/components/previews"

Required when there is more than one path defined in preview_paths. Defaults to ‘“”`. If this is blank, the generator will use `ViewComponent.config.previews.paths` if defined, `“test/components/previews”` otherwise

#### ‘#use_component_path_for_rspec_tests`

Whether to use ‘config.generate.path` when generating new RSpec component tests:

config.view_component.generate.use_component_path_for_rspec_tests = true

When set to ‘true`, the generator will use the `path` to decide where to generate the new RSpec component test. For example, if the `path` is `app/views/components`, then the generator will create a new spec file in `spec/views/components/` rather than the default `spec/components/`.

Returns:

  • (ActiveSupport::OrderedOptions)

.instrumentation_enabled ⇒ Boolean

end

.previews ⇒ ActiveSupport::OrderedOptions

The subset of configuration options relating to previews.

#### ‘#controller`

The controller used for previewing components. Defaults to ‘ViewComponentsController`:

config.view_component.previews.controller = "MyPreviewController"

#### ‘#route`

The entry route for component previews. Defaults to ‘/rails/view_components`:

config.view_component.previews.route = "/my_previews"

#### ‘#enabled`

Whether component previews are enabled. Defaults to ‘true` in development and test environments:

config.view_component.previews.enabled = false

#### ‘#default_layout`

A custom default layout used for the previews index page and individual previews. Defaults to ‘nil`:

config.view_component.previews.default_layout = "preview_layout"

Returns:

  • (ActiveSupport::OrderedOptions)

#current ⇒ ViewComponent::Config
