SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill provides a structured approach to building Ktor-based HTTP servers with consistent patterns for routing, plugins, authentication, DI, serialization, and testing.

Core Features & Use Cases

  • Routing DSL: Define clean, modular routes using Ktor's DSL for maintainable endpoints.
  • Authentication & Security: Set up JWT or session-based auth with reusable security configuration.
  • DI & Modularity: Use Koin for dependency injection and a clean module-driven project structure.
  • Serialization: Configure kotlinx.serialization for JSON APIs and custom serializers.
  • WebSockets & Testing: Include WebSocket support and testApplication-based testing scaffolds.
  • Use Cases: Rapidly spin up REST-like services with deterministic routing, DI, and tests.

Quick Start

Create a minimal Kotlin Ktor API skeleton with routing, DI, serialization, auth, and a basic test suite.

Frequently Asked Questions about kotlin-ktor-patterns

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I structure a Kotlin Ktor server for modular routing and dependency injection?▼

Structure a Kotlin Ktor server by using Ktor's Routing DSL for explicit endpoints and Koin for dependency injection. This blueprint provides a modular architecture that separates routing definitions from business logic.

What's the best way to configure JSON serialization in a Ktor HTTP server?▼

Configure JSON serialization in a Ktor server using kotlinx.serialization. This pattern sets up custom serializers for JSON APIs, ensuring deterministic data exchange across typical REST endpoints.

Can I use Koin for dependency injection in a Kotlin Ktor application?▼

Yes, you can use Koin for dependency injection in a Kotlin Ktor application. The pattern integrates Koin to manage modularity and provide dependencies explicitly across server components.

How do I set up authentication and WebSocket support in Ktor?▼

Set up authentication and WebSockets in Ktor by applying reusable plugin configurations. The blueprint supports JWT or session-based auth alongside WebSocket channels for real-time communication.

How do I write tests for a Ktor server using testApplication?▼

Write tests for a Ktor server using the testApplication scaffold. The blueprint provides test structures to verify routing, serialization, and plugin behavior across typical REST APIs.

Does this Ktor server pattern require specific external libraries for rapid API development?▼

The Ktor server pattern requires no external libraries outside the specified dependencies. It leverages Ktor's native plugins, Koin for DI, and kotlinx.serialization for JSON APIs to enable rapid API development.
