HOCON

Wrapper around lightbend/config along with JSON serialization support.

The primary use case is in service of kairo-config.

Installation

Install kairo-hocon. You don’t need to install lightbend/config separately — it’s included by default.

build.gradle.kts

dependencies {
  implementation("com.highbeam.kairo:kairo-hocon")
}

Usage

The KairoJson.deserialize(hocon) extension converts an HOCON Config object to a typed data class. Internally, the HOCON tree is rendered as JSON and then deserialized by Jackson.

data class Config(
  val rest: RestFeatureConfig,
  val sql: SqlFeatureConfig,
)

val json: KairoJson = KairoJson()

val hocon = ConfigFactory.parseResources("config/$configName.conf").resolve()

json.deserialize<Config>(hocon)

You generally won’t use this module directly. kairo-config uses it under the hood to load and deserialize HOCON config files.
