👻🔎 BooTrack

This is a sample Compose Multiplatform for desktop project accompanying the KotlinConf 2025 talk for the Exposed library. It mimics a simplified project-issue tracker model, reminiscent of YouTrack.

Run Desktop Application (using JDBC)

• Run Ktor Gradle task buildFatJar
• Run docker compose up
• The server responds at http://127.0.0.1:8080 to check routes, if needed.
  • See details about the Ktor server application in the backend-jdbc module
  • See details about the Ktor HttpClient in the composeApp/commonMain/../client package
• Once the server has started, run Main.kt from the composeApp/desktopMain: task main [desktop]

Note that the default data access approach is set to the Domain Specific Language (DSL) approach. This can be changed to the Data Access Object (DAO) approach in application.conf by commenting out the desired dataAccess property.

Note that the server will automatically shut down as a part of the application exit process.

Run Desktop Application (using R2DBC)

Note

docker-compose.yml is set up by default to use a PostgreSQL JDBC driver. The correct Dockerfile must be added to properly use the PostgreSQL R2DBC driver instead.

• In docker-compose-yml, make sure the backend/build argument is set to dockerfile: Dockerfile.r2dbc
• Run Ktor Gradle task buildFatJar
• Run docker compose up
• The server responds at http://127.0.0.1:8080 to check routes, if needed.
  • See details about the Ktor server application in the backend-r2dbc module
  • See details about the Ktor HttpClient in the common/commonMain/../client package
• Once the server has started, run Main.kt from the composeApp/desktopMain: task main [desktop]

Note

Use of exposed-dao is not currently supported with exposed-r2dbc, so only a DSL approach is provided.

Note

Geography & TsVector types are not yet supported by the PostgreSQL R2DBC driver, so attempting to set or search by location, or to use full text search queries, will be ignored by the app if run using R2DBC.

Note that the server will automatically shut down as a part of the application exit process.
