Building asynchronous API with Ktor & Kotlin

on YouTube ↗21m

" summary

Shows a small Ktor project scaffolded for Kotlin using Ktor + coroutines and JSON serialization, with Application.kt, routing extensions, a fake Map repository and a service layer. Implements full CRUD: GET returns list, POST receives JSON and returns HTTP 201, GET by id validates params and returns 400/404, PUT updates, DELETE returns 204 when removed. Uses suspend handlers so threads stay nonblocking, recommends Exposed ORM for real DBs, and the demo runs with expected HTTP status codes.
