Muviz is a modern Android application built with Jetpack Compose that serves as a movie and TV show discovery client for the TMDB API. It follows a clean MVVM architecture with feature-based packaging, using Hilt for dependency injection, Retrofit for networking, Room for local favorites persistence, and the Paging 3 library for efficient data loading. The app provides a bottom-navigation interface with Home, Search, Favorites, and Account screens, supporting both movies and TV series with categories like trending, popular, upcoming, and top-rated. It includes a custom theme system with light, dark, system, and Material You options, and features animated UI components such as a vote average arc indicator and swipe-to-delete on favorites. The codebase is well-structured and uses modern Android development practices, though some screens (like cast details) are incomplete and there is some code duplication in ViewModels.
FirebaseUI-Android is an open-source library providing pre-built UI components for Firebase Authentication, Realtime Database, Cloud Firestore, and Cloud Storage. It is a multi-module Android library published on Maven Central. The primary module, `firebase-ui-auth`, has been rewritten in Jetpack Compose with Material 3, offering a high-level composable (`FirebaseAuthScreen`) and a Kotlin DSL for configuration. It supports 12+ identity providers (Google, Facebook, Email, Phone, Apple, etc.), multi-factor authentication (SMS/TOTP), credential linking, anonymous upgrade, and email link sign-in. The `firebase-ui-database` and `firebase-ui-firestore` modules provide RecyclerView adapters with paging support (AndroidX Paging 3) for displaying Firebase data. The `firebase-ui-storage` module integrates with Glide for loading images from Firebase Storage. A demo app and end-to-end tests against the Firebase Auth Emulator are included. Architecturally, the library is split into separate Gradle modules: `auth`, `database`, `firestore`, `storage`, `common`, and `lint`. The auth module uses Kotlin coroutines, StateFlow, and a sealed class state machine (`AuthState`) to manage authentication flows. The database/firestore modules are older Java-based implementations using lifecycle-aware adapters and observable arrays. The library maintains a version catalog (libs.versions.toml) with modern dependencies (Kotlin 2.4.10, AGP 9.3.0, Compose BOM 2026.06.01). Key entry points include `FirebaseAuthScreen` (Compose), `FirebaseAuthUI` (singleton for sign-out/delete/auth state), `AuthFlowController` (Activity-based alternative), `FirebaseRecyclerAdapter`/`FirestoreRecyclerAdapter`, and `FirebaseImageLoader` (Glide integration). The primary data flows involve Firebase SDKs for authentication, database listeners, and image loading. The library is designed to be embedded in host Android apps, handling complex auth flows with minimal developer effort. The codebase demonstrates strong craftsmanship in the auth module’s state machine and Compose UI, but shows signs of technical drift due to mixed UI generations (legacy XML layouts alongside new Compose), some deprecated API usage (e.g., `fetchSignInMethodsForEmail`, `startActivityForResult`), and incomplete localizations. The database/firestore modules are mature but use older patterns. Overall, the library is well-structured and actively maintained, with a beta version (10.0.0-beta04) indicating ongoing development.
This is the source code for `@swimlane/ngx-datatable`, an Angular component library for building high-performance, feature-rich data tables. It provides virtual scrolling, client- and server-side sorting/paging, column reordering/resizing, row selection (single, multi, checkbox), tree view, row grouping, summary rows, and extensive custom template support. The library is built with Angular's signals-based reactivity and OnPush change detection, offering a modern reactive API. The repository also includes a comprehensive demo application and a test suite using Vitest, Angular CDK ComponentHarness, and Playwright for E2E. While the codebase demonstrates strong architectural patterns and reusable utilities, it suffers from a high number of open issues (917), some deprecated API surfaces, and a test stack in migration flux, indicating a mature but somewhat stale maintenance state.
