org.cameek.spring_sandbox is a minimal Kotlin + Spring Boot 3 playground that demonstrates how to consume the Bitfinex public REST API and expose the data through a reactive WebFlux endpoint. Use it as a starting point for experimenting with Spring Boot 3, WebFlux, Kotlin, and Gradle.
- Reactive WebFlux REST API:
GET /bitfinex/last-month-datastreams the last 30 daily candles (1‑day timeframe) for BTC/USD. - **Non‑blocking **`` to call Bitfinex’s public Candles endpoint.
- Simple `` (timestamp, open, close, high, low, volume) for fast JSON mapping via Jackson‑Kotlin.
- Gradle Wrapper (8.13) with Kotlin DSL — zero global toolchain setup.
- Works out‑of‑the‑box on JDK 17–21.
- JDK 17+ (tested with Temurin 21).
- Git.
# clone the repo
git clone https://github.com/your‑org/org.cameek.spring_sandbox.git
cd org.cameek.spring_sandbox
# run the app
./gradlew bootRun # use gradlew.bat on WindowsGradle will download all dependencies automatically.
Once the app is running (default port 8080):
GET http://localhost:8080/bitfinex/last-month-data
Example with curl:
curl http://localhost:8080/bitfinex/last-month-data | jq[
{
"timestamp": 1712188800000,
"open": 70345.0,
"close": 70812.0,
"high": 71200.0,
"low": 68200.0,
"volume": 1234.5678
}
// …29 more candle objects
