Johannes Schickling Discusses Transition to Client-Side Event Sourcing and Local-First Development
Key points
- Local-First shifts data bottlenecks from server to client for performance.
- Event sourcing offers robust history; CRDTs excel in conflict resolution.
- Transitioning to Local-First requires careful planning for data structures.
- Not all applications benefit from Local-First due to architectural complexity.
Rethinking Data Architectures
Johannes Schickling, known for founding Prisma, has explored moving beyond the conventional three-tier web stack. His current focus is on a local-first development approach, which he implemented in his music curation application, Overtone. This shift involves leveraging client-side event sourcing and SQLite.
Local-First Development Principles
Local-First development aims to move the data bottleneck from the server to the client, enabling high-performance and responsive user experiences. This approach prioritizes offline support and user data ownership, contrasting with server-centric models. Schickling's work with Overtone exemplifies this architectural change.
Event Sourcing vs. CRDTs
The discussion covered the trade-offs between event sourcing and Conflict-free Replicated Data Types (CRDTs) in local-first contexts. Event sourcing provides a robust history of changes, while CRDTs are designed for collaborative conflict resolution. The choice between these depends on specific application requirements and the need for historical data versus real-time collaboration.
Implementation Challenges and Considerations
Adopting a local-first architecture requires significant upfront planning, particularly in breaking down monolithic data structures into smaller, manageable units. Not every application is suitable for this paradigm; developers must assess if the benefits, such as offline capability and data ownership, justify the increased architectural complexity. Modern frameworks like LiveStore offer solutions for data portability and security within local-first systems.
