Implement a lightweight, secure JWT auth layer in Ktor using the built‑in Authentication plugin and a small relational revocation table. The design balances statelessness, scalability, and revocation control, with clear trust boundaries, operational hooks, and failure‑mode guidance.
Hardcoded string paths in Ktor routes hide renaming bugs until runtime. The Resources plugin turns endpoints into typed classes so the compiler catches mismatches — here's how to set it up and where it falls short.
Learn how Ktor’s ContentNegotiation plugin removes manual JSON boilerplate by automatically serializing Kotlin data classes to JSON.
Ktor's Resources plugin turns URL routes into typed classes, converting runtime 404s and parsing bugs into compile errors. Here's how it works, where it pays off, and where plain strings still win.
Learn how to wire Ktor’s ContentNegotiation plugin with kotlinx.serialization to accept and return Kotlin data classes, see a working route, run an in‑process test, and understand the trade‑offs versus heavier frameworks.
Ktor's ContentNegotiation plugin lets one route serve JSON and XML based on the client's Accept header. Here's how to configure it, when to override it per route, and how to test the negotiation contract.
Step-by-step guide to building a production-ready Ktor 2.x server on Netty with kotlinx.serialization JSON, typed routing, StatusPages error mapping, HOCON config, and graceful SIGTERM shutdown. Includes aligned dependencies, plugin order, runnable code, curl verification, and testApplication tests.
Learn how to pick CIO, Jetty, or Apache engines in Ktor, see a code example, and understand the trade‑offs.
Ktor’s ContentNegotiation plugin with kotlinx.serialization turns JSON handling into a declarative line of code. This blog walks through setup, a concrete example, performance trade‑offs, common pitfalls, and a quick benchmark test.
