Client-Side Databases

Store data locally in the browser with IndexedDB or TursoDb

BlazorEssentials provides two client-side database options for Blazor WebAssembly applications, enabling offline-capable, local-first experiences.

IndexedDB

NoSQL key-value storage using the browser’s built-in IndexedDB API. Great for caching, offline data, and simple object storage.

TursoDb

Full SQLite database with SQL queries, transactions, and optional Turso Cloud sync for multi-device experiences.

Choosing a Database

Query Language	JavaScript API	SQL
Relationships	Manual	Foreign keys
Transactions	Yes	Yes
Cloud Sync	No	Yes (Turso Cloud)

Use IndexedDB for simple caching and document storage. Use TursoDb when you need SQL queries, relationships, or cloud synchronization.
