Web Development in Kotlin: From Basics to Deployment

"Web Development in Kotlin: From Basics to Deployment" is a practical guide that will take you through all stages of creating modern web applications in Kotlin. The book covers the journey from basic syntax to deploying a finished product in a production environment.

Kotlin has long since moved beyond Android development and become a powerful tool for building backend systems. Thanks to its conciseness, type safety, and full compatibility with the Java ecosystem, this language is ideal for web development.

What you will learn from the book:

• Kotlin Basics: syntax, null safety, functional programming, coroutines, and working with threads.
• Frameworks: in-depth study of Ktor (lightweight asynchronous framework) and Spring Boot (industry standard).
• Working with Databases: Exposed ORM, Spring Data JPA, migrations, and schema design.
• REST API: creating endpoints, serialization with kotlinx.serialization, request validation.
• Authentication and Authorization: JWT, OAuth2, sessions, and role-based models.
• Testing: unit tests, integration testing, Testcontainers.
• Deployment: Docker containerization, CI/CD pipelines, cloud platforms (Heroku, AWS, DigitalOcean).

Who this book is for:

• Java developers looking to switch to a more modern and expressive language.
• Android developers who want to learn backend development.
• Beginner programmers with a foundation in any programming language.
• Students in technical fields studying modern technologies.

All code examples are available for download and come with step-by-step instructions. You won't just read theory—you will build a complete web application from the first line of code to running it on a server.

The book is written in simple and clear language, without excessive academic style. The author shares proven practices and real-world cases from commercial development. Special attention is given to common mistakes and how to avoid them.

After reading, you will be able to confidently develop web applications in Kotlin, use modern frameworks, set up databases, write tests, and deploy projects to the cloud. This is an ideal start for a career as a Kotlin developer or an expansion of an experienced programmer's toolkit.

Whether you are building a microservice for a startup or a corporate application, this book will give you all the necessary knowledge and skills for successful work.
