Build microservice in Kotlin without prior Java knowledge, using REST and GraphQL
In this course, we’ll build a microservice using Kotlin programming language and Ktor framework, then deploy it to Heroku.
The microservice will be for a cat hostel. You’ll be able to add new cats, remove and list them.
Because as long as you know how to implement basic operations, you can build it any kind of service you may need: supermarket orders, auction items, taxis, you name it. So, why not cats?
- Modern, productive and highly pragmatic language
- Type safe
- Generics that actually make sense
- Highly concurrent: Kotlin uses coroutines on top of best-in-class JIT provided by the JVM, that makes it one of the most efficient and concurrent languages nowadays
- Rich ecosystem: be it PostgreSQL, Kafka or RabbitMQ, the most solid libraries are written for the JVM. And Kotlin is able to make use of all of them
Why this course?
There are many good tutorials and books about Kotlin programming language nowadays. But most of them make the assumption that you’re either and Android developer or at least familiar with Java programming language and its ecosystem.
This course make no such assumptions. If you’re and experienced PHP, Python, Ruby or NodeJS developer, with zero Java knowledge, this course was build with you in mind.
What you need to know:
Familiarity with Git. I’ll provide you with a link to the relevant branch on GitHub after most of the videos, and I’ll show you commands that I use, but I won’t dive deep into what they do.
Basic SQL and Docker knowledge is useful, but not mandatory.
