Synopsis

A journey story about how we re-engineered a set of high-traffic services at a major Academic Publisher to use http4k, a Server-as-a-Function framework written in Kotlin.

We'll cover the concepts behind Server-as-a-Function, then how we extended those concepts to create http4k, which provides typesafe HTTP routing. Finally, we'll see how the new approach reinvented how we implemented microservice testing strategies, and allowed the applications to be fully Continuously Deployed.
