Develop a Geospatial Webservice with Kotlin and Spring Boot

Through a geolocated chat application allowing you to discuss with the people located close to you, I will show you how the combined use of Kotlin and Spring Boot allows to develop simply and equally powerful applications.

Those aspects will be mentioned in a concrete way with many code examples from this application:

Super-powerful indifference for concise and 0 overhead code:

-Excellent Java interoperability

– Code security, via a better care of zero values

– Quick to write, easy to read

It will also be the occasion to show you how to use a relational database via an API Kotlin SQL type-safe without generating code, in order to use simply the functionalities of PostgreSQL such as its geographic cartbridge PostGIS or the JSON native support while keeping a light and optimized tech stack. You will also see in exclusivity how a preservation of Kotlin2js allows to develops the front in Kotlin in order to benefit from the autocompletion and share some code with the server.

You can have a taste of what I will present in [this article].
