Reference

Reference is the map: factual, complete, and consistent. Use it to look things up — the application DSL, the discovery interfaces, configuration keys, and every subsystem. For learning or task-oriented help, see the tutorial and how-to guides.

Foundations

• Module map — every published artifact, its purpose, and its Maven coordinates.
• Application DSL — katalystApplication { … } and every block it accepts.
• Dependency injection & auto-wiring — the discovery interfaces and the parameter-injection rules.

Configuration

• Configuration — ConfigProvider, the typed configuration binding patterns (ConfigBinder, @ConfigPrefix, ConfigBinding), and every recognized key.

Data

• Persistence — Table, mapping, CrudRepository, SqlExecutor, DatabaseConfig.
• Transactions — transactionManager, TransactionConfig, retry, and isolation.
• Migrations — KatalystMigration, MigrationRunner, MigrationOptions.

Application features

• Scheduler — requireScheduler, the jobs DSL, ScheduleConfig, CronExpression.
• Events — DomainEvent, EventHandler, EventBus, side effects, deduplication.
• Ktor integration — katalystRouting, katalystMiddleware, katalystWebSockets, katalystExceptionHandler, ktInject.

Testing

• Testing — katalystTestEnvironment, katalystTestApplication, inMemoryDatabaseConfig, FakeConfigProvider.
