Comprehensive Ktor patterns for building robust, maintainable HTTP servers with Kotlin coroutines. Building Ktor HTTP servers Configuring Ktor plugins (Auth, CORS, ContentNegotiation, StatusPages) Implementing REST APIs with Ktor Setting up dependency injection with Koin Writing Ktor integration tests with testApplication Working with WebSockets in Ktor | Pattern | Description | |---------|-------------| | route("/path") { get { } } | Route grouping with DSL | | call.receive () | Deserialize request body | | call.respond(status, body) | Send response with status | | call.parameters["id"] | Read path parameters | | call.request.queryParameters["q"] | Read query parameters | | install(Plugin) { } | Install and configure plugin | | authenticate("name") { } | Protect routes with auth | | by inject () | Koin dependency injection | | testApplication { } | Integration testing | Remember: Ktor is designed around Kotlin coroutines and DSLs. Keep routes thin, push logic to services, and use Koin for dependency injection. Test with testApplication for full integration coverage.
