In the blog post "How to Build Robust Offline-First Apps," the focus is on using Conflict-Free Replicated Data Types (CRDTs) and Ditto's sync model to develop offline-first applications that handle data conflicts efficiently. It challenges traditional methods of enforcing data consistency through a single source of truth, which can lead to complexity and poor observability, especially in offline scenarios where connectivity is unpredictable. The article provides real-world examples like restaurant payment systems and task management in maintenance apps to demonstrate how embracing data conflicts and using application-level conflict resolution can enhance system resilience and transparency. By capturing all outcomes and resolving their meaning within the application, developers can maintain a seamless user experience while retaining control over business outcomes, without the need for custom sync code. This approach not only improves the auditability and uptime of applications but also turns conflict resolution into a competitive advantage by providing clear, domain-focused code and enabling a more robust and intelligent system.
