Modern Web Development with Kotlin

A concise and practical step-by-step guide

About the Book

In this book, you will learn how to use Kotlin to build Web applications on top of Vert.x, access databases, test and deploy your code. You will also learn to use Gradle and integrate it with Webpack, Sass and React.

The book doesn't expect any prior Kotlin experience as the basics are briefly explained in the first chapters. The required functional programming concepts are also explained in the beginning.

Who this book is for

This book is intended for people who are interested in learning Kotlin and applying it for writing Web applications. It assumes a good knowledge of any programming language and familiarity with Web technologies.
