This is a mature, community-maintained Ember.js addon that provides native Ember components for Bootstrap 4 and 5. The addon replaces Bootstrap's JavaScript with Ember-centric implementations (Glimmer components, modifiers, helpers), allowing developers to use Bootstrap's CSS without jQuery or Bootstrap.js. The monorepo (pnpm workspaces) contains the addon itself, a test application, and a documentation app. The codebase is well-structured, with extensive integration tests and a comprehensive pattern library. Recent activity shows active migration to TypeScript, conversion to Glimmer components, and continued support for both Bootstrap versions. The addon is highly reusable within the Ember ecosystem, but its components are tightly coupled to the addon's internal architecture, limiting direct extraction without modification. Standalone utilities like the transition-end promise wrapper and the conditional-attribute modifier are more independently reusable.
