Кратко

Ktor is a Kotlin web framework for building APIs and web servers, built on async I/O and coroutines. Lightweight, type-safe, no magic. Mastery takes 4-6 weeks. Practitioners earn 20-30% premium because they ship type-safe APIs faster than Java/Spring. The 5% who design high-performance Ktor services (100k+ req/sec) are valuable.

Что такое Ktor Kotlin

Ktor is a Kotlin web framework for building asynchronous HTTP services and APIs. Built on Kotlin coroutines, it's lightweight, high-performance, and philosophically minimal (you choose persistence, validation, logging, no batteries-included). Routing is type-safe, serialization is explicit (using kotlinx.serialization), and the async model is first-class. Ktor supports both client and server use cases. Server side: build REST APIs, WebSockets. Client side: make HTTP requests with coroutines.

❓ Частые вопросы

How is Ktor different from Spring Boot?

Spring Boot is enterprise, full-featured (ORM, security, actuator). Ktor is lightweight, coroutine-first, minimal. Spring good for large monoliths; Ktor good for microservices, APIs. Ktor startup: 100ms, Spring: 5s.

What are coroutines?

Coroutines are lightweight threads (100k+ per process). I/O operation (network, disk) suspends coroutine, frees thread. Thousands of concurrent requests on 1 thread. Ktor built on coroutines natively.

Can I use Ktor with databases?

Yes. Use Exposed (Kotlin ORM) or direct SQL libraries. Ktor doesn't dictate persistence layer. Expose ORM is coroutine-aware.

Is Ktor production-ready?

Yes. Used by JetBrains, Grab, others. Ktor 2.0+ is stable. Good choice for new Kotlin projects.
