TvManiac is a personalized entertainment tracking and recommendation Multiplatform app (Android & iOS) for tracking TV Shows. By utilizing Trakt and TMDB, you can discover shows, manage your watchlist, track watch progress, and get personalized recommendations.

Under Heavy Development

This is my playground for learning Kotlin Multiplatform. With that said, I'm sure it's filled with bugs crawling everywhere, and I'm probably doing a couple of things wrong. So a lot is changing, but that shouldn't stop you from checking it out.

Install

Getting Started

Requirements

• Zulu Java 21
• Latest Android Studio
• KMM Plugin

API Keys

The app requires TMDB and Trakt API credentials. See docs/setup.md for detailed instructions.

Create local.properties in the project root:

TMDB_API_KEY=your_tmdb_api_key
TRAKT_CLIENT_ID=your_trakt_client_id
TRAKT_CLIENT_SECRET=your_trakt_client_secret
TRAKT_REDIRECT_URI=tvmaniac://callback

Setup & Build

./scripts/install-git-hooks.sh

Android:

./gradlew :app:assembleDebug

iOS: Open ios/tv-maniac.xcodeproj in Xcode and run.

Architecture

The project follows Clean Architecture with a modular design organized by feature and layer. Business logic and state management live in shared KMP code, while Android (Compose) and iOS (SwiftUI) contain only UI rendering.

Key Concepts

A few foundational libraries and patterns drive the architecture.

• Decompose. Shared navigation and lifecycle for KMP. The navigation stack, child components, and back handling all live in shared Kotlin code. Android (Compose) and iOS (SwiftUI) only render the active child. See Navigation.
• Metro. Compile time dependency injection. There is no KSP processor and no runtime reflection. Modules expose interfaces from api/ packages, implementations are bound with @ContributesBinding, and the full graph is assembled at the app entry point. See Dependency Injection.
• Store pattern. One fetch and cache pipeline per data type. A Store combines a Fetcher (network), a SourceOfTruth (SQLDelight DAO), and a Validator (cache freshness via RequestManager). Presenters never call the network or DAO directly. See Data Layer.
• Interactor and SubjectInteractor. Thin orchestration in the domain layer. An Interactor runs a one shot action (mark watched, sign in). A SubjectInteractor exposes a continuous Flow of data (observe show details). Presenters compose these into screen state. See Presentation Layer.

Tech Stack

Architectural choices (Decompose, Metro, Store) are described in Key Concepts above. The libraries below cover the rest of the shared and platform stack.

Shared (KMP)

• Kotlin Coroutines - Concurrency
• Ktor - Networking
• SQLDelight - Local database
• kotlinx.serialization - JSON serialization
• Multiplatform Paging - Pagination

Android

• Jetpack Compose - UI toolkit
• Coil - Image loading
• AppAuth - OAuth authentication

iOS

• SwiftUI - UI framework
• Nuke - Image loading
• OAuthSwift - OAuth authentication

Gradle Convention Plugins

Build configurations are managed by app-gradle-plugins, a set of custom Gradle convention plugins published to Maven Central. They handle Android/KMP module setup, versioning, release automation, and R8 optimization. For a deep dive into how they work, see Publishing Gradle Convention Plugins.
