Description

A lightweight Kotlin service that integrates with Wire's SDK. Combines Javalin (HTTP server), Koin (DI), and Wire SDK to handle incoming messages and expose REST endpoints.

Tech Stack

• Kotlin 2.2.0 / JDK 21
• Javalin 6.7.0 (web framework)
• Koin 4.1.1 (dependency injection)
• Wire Apps JVM SDK 0.0.18

Architecture: Lightweight Clean Architecture

Organized in three layers:

• Core (com.wire.apps.jira.core): Domain logic, use cases, interfaces
• API (com.wire.apps.jira.api): HTTP controllers and message handling
• Infrastructure (com.wire.apps.jira.infra): External clients (HTTP, Wire SDK), config, implementations

Wire SDK's WireApplicationManager is initialized in the DI layer and starts listening for incoming messages at startup.

Getting Started

Requirements

• JDK 21
• Gradle (included: ./gradlew)

Environment Variables

Set these before running the app:

Jira related

• JIRA_TOKEN
• JIRA_URL
• JIRA_USERNAME

SDK related

• WIRE_SDK_EMAIL
• WIRE_SDK_ENVIRONMENT
• WIRE_SDK_PASSWORD

Build & Run

# Build
./gradlew build

# Run (listens on port 8888 by default)
java -jar build/libs/javalin-app-1.0-SNAPSHOT.jar

Alternatively, set env vars and start:

export WIRE_API_TOKEN=your-token
export WIRE_CRYPTO_PASSWORD=your-32-byte-password
java -jar build/libs/javalin-app-1.0-SNAPSHOT.jar

Notes

• Port 8888 is hardcoded in Main.kt; update if needed.
• See ModulesConfig.kt for Wire SDK initialization and DI setup.
• Message handling is mapped in CommandHandler → routed to use cases in core/.
