Mixter
Learn CQRS and Event Sourcing through interactive koans in multiple programming languages.
What is Mixter?
Mixter is an open-source educational project that teaches CQRS (Command Query Responsibility Segregation) and Event Sourcing through interactive koans—coding exercises where users fix failing tests to learn concepts step-by-step. It implements a social messaging domain to demonstrate how these architectural patterns work in practice, helping developers move from theory to hands-on experience.
Developers and software architects who want to learn or deepen their understanding of CQRS and Event Sourcing patterns through practical, language-agnostic exercises.
Mixter offers a unique, hands-on approach to learning complex architectural patterns by providing koans in multiple languages, allowing developers to focus on concepts rather than setup, with clear progression and example solutions.
