ember-simple-auth is a lightweight Ember.js addon for implementing authentication and authorization in Ember applications. It provides a session service, pluggable authenticators (OAuth2 password grant, implicit grant, Devise, Torii, and custom), and session stores (localStorage, sessionStorage, cookie, adaptive, ephemeral) that persist the session across page reloads and synchronize across browser tabs. The library supports FastBoot, Engines, and Embroider, and includes built-in test helpers. Architecture follows a service-based pattern where the session service delegates to an internal session module that manages state transitions (unauthenticated, authenticated, loading) and communicates with authenticators and stores via events. The codebase is partially migrated to TypeScript, uses modern tooling (pnpm workspaces, Rollup, eslint flat config), and maintains broad compatibility with Ember versions from 3.28 onward.
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.
ember-cli-materialize is an Ember.js addon that provides Materialize CSS components as Ember components. It allows developers to use Materialize UI elements (buttons, cards, modals, forms, etc.) in Ember applications by wrapping them in Ember-friendly components. The addon imports Materialize CSS and fonts, provides a comprehensive set of UI components, and handles the integration between Ember's runloop and Materialize's JavaScript plugins. It follows Ember CLI addon conventions with components, templates, styles, initializers, and services organized in standard directories.
ember-sortable is an Ember.js addon providing sortable UI primitives for drag-and-drop reordering of lists, grids, and tables. It implements modifiers (sortable-group, sortable-item, sortable-handle) that attach drag-and-drop behavior to DOM elements, with built-in support for mouse, touch, and keyboard input. The architecture centers around a service (ember-sortable-internal-state) that manages state between sortable groups and items, enabling features like visual feedback during drag, automatic container scrolling, and accessibility support including screen reader announcements and keyboard navigation. The library follows Ember addon conventions with a modular structure, clear separation of concerns, and comprehensive test coverage.
Ember Data Factory Guy is an Ember.js addon designed for factory-based testing in Ember Data applications. It replaces traditional fixtures with factory definitions to generate test data, providing methods like `make`, `build`, and `mock*` for creating and persisting test records. The addon includes request mocking capabilities supporting both Pretender and MSW libraries, scenario management for test setup, and serializer-specific builders/converters for JSONAPI, REST, JSON, and ActiveModel formats. Architecture follows Ember addon conventions with a clear separation between core factory logic, adapter-specific handling, and mocking abstraters. The test application demonstrates usage patterns but is not the primary product.
