Live-coding a web server with Ktor
Ktor is a Kotlin framework dedicated to building asynchronous servers and clients in connected systems. In this session, I will explain and demo the core concepts of Ktor 2 by live coding an HTTP server from scratch using Ktor Server. Also, we'll take an overview of Ktor Client, from setting it up to making requests and installing plugins.
Getting Started
The purpose of this live session will be to send a POST request with a list of names to our web server and our web server will send a random value from this list. It’s a very simple call but it covers a lot of things from Ktor.
