Constant Summary collapse

VALID_ASSET_MODES =

How the host app loads Bootstrap's assets. rails g bootstrap:install cdn writes an initializer setting this to :cdn; bootstrap:layout reads it to pick its default. Defaults to :static so the layout generator works whether or not that initializer exists.

[:static, :cdn].freeze
VERSION = 
"5.4.0"
BOOTSTRAP_VERSION =

The Bootstrap release this gem vendors and links to. The gem version no longer tracks it; this constant is the authoritative statement.

"5.3.8"
POPPER_VERSION = 
"2.11.8"
BOOTSTRAP_CDN =

URLs and Subresource Integrity hashes exactly as published on https://getbootstrap.com/docs/5.3/getting-started/introduction/ Bumping Bootstrap means editing this hash and re-vendoring the dist files.

def asset_mode
  @asset_mode
end

.asset_pipeline ⇒ Object

Which asset pipeline the host app runs. Propshaft (the Rails 8 default) has no Sprockets directives: a //= require line in a manifest is an inert comment there, so assets have to be linked explicitly instead.
