IndexedDB provides client-side database storage for large amounts of structured data, enabling offline-first applications and improved performance through local data caching. As the creator of CoreUI, a widely used open-source UI library, I’ve implemented IndexedDB solutions in production Vue applications throughout my 12 years of frontend development since 2014. The most practical approach is creating a composable that wraps IndexedDB operations with reactive Vue refs and proper error handling. This method provides type-safe database access, reactive data synchronization, and seamless integration with Vue’s composition API and component lifecycle.
