How does it handle error responses?

It utilizes the StatusPages plugin to catch specific exceptions like Unauthorized or NotFound and transform them into standardized JSON response objects.

Can I use this for JWT authentication?

Absolutely. It provides boilerplate for JWT verifiers, validation logic, and the 'authenticate' DSL for protecting specific API endpoints.

Does this skill support Koin dependency injection?

Yes, it includes patterns for setting up Koin modules, providing dependencies to routes, and configuring mock modules for testing.

Is testing included in these patterns?

Yes, the skill covers integration testing using Ktor's testApplication engine, allowing you to simulate requests and verify server behavior without a full deployment.

API Development

Implements production-ready Ktor server architectures using idiomatic Kotlin patterns, routing DSLs, and dependency injection.

This skill provides a comprehensive blueprint for building robust, maintainable backends with the Ktor framework. It streamlines the implementation of essential server components including structured routing, Koin dependency injection, JWT-based authentication, and centralized error handling via StatusPages. Whether you are scaffolding a new REST API or integrating complex middleware like CORS and kotlinx.serialization, this skill ensures your Ktor application follows industry-standard project layouts and testing practices.
