Guides

Chronicle task guides are shared across clients. They live in the main Chronicle docs and use synchronized language tabs for Kotlin, Java, C#, Elixir, and TypeScript examples.

Start with:

• Appending events
• Read models
• Projections
• Reactors
• Reducers
• Constraints
• Event evolution

Guides for the JVM client

These cover what only the Kotlin and Java client does:

• Wiring Chronicle into Spring Boot
• Controlling what gets registered, and when
• Testing a slice without a kernel
• Declaring strongly-typed identifiers
• Seeding events
• Event sources and streams
• Reacting to read model changes
• Capturing external sources
• Registering external services
• Tracing with OpenTelemetry
• Migrating append routing

Use the Kotlin client section for setup and API reference.
