## What it is
Thinkter is an official Kotlin full-stack sample application implementing a simple microblogging app, with a Ktor/JVM backend exposing a REST API and a React-based browser frontend written in Kotlin/JS. The repository is deprecated in favor of the newer kotlin-full-stack-application-demo project.

## Use cases
- learn how to build a full-stack web app in Kotlin
- example of Ktor backend with REST API
- see how to use React from Kotlin/JS
- reference for Kotlin frontend Gradle plugin setup
- starting point for a Kotlin JVM + browser project
- understand full-stack Kotlin project structure

## When to choose
- you want a worked example of a complete Kotlin full-stack application
- you are learning Ktor and Kotlin/JS together in one project
- you need reusable Kotlin wrappers for React APIs

## When to avoid
- you need a maintained template with current Kotlin and Kotlin/JS Gradle plugin versions - use the successor kotlin-full-stack-application-demo instead
- you want a production-ready application skeleton
- you need a non-deprecated build setup, since this sample uses plugins that will be deprecated

## Facets
