+ + Storage Example +

+

+ Demonstrates IndexedDB + Spark KV hybrid storage +

+
+ +
+ + + Simple Counter (useStorage) + + +
+ + {counter} + +
+ +

+ This counter persists across page refreshes using hybrid storage +

+ + + + + + Todo List (useStorage) + + +
+ setNewTodoText(e.target.value)} + placeholder="Enter todo..." + onKeyDown={(e) => e.key === 'Enter' && addTodo()} + /> + +
+ +
+ {todos.length === 0 ? ( +

+ No todos yet. Add one above! +

+ ) : ( + todos.map((todo) => ( +
+ toggleTodo(todo.id)} + className="w-4 h-4" + /> + + {todo.text} + + +
+ )) + )} +
+ +

+ Todos are stored in IndexedDB with Spark KV fallback +

+ + +
+ + + + How It Works + + +
+
+

1. Primary: IndexedDB

+

+ Data is first saved to IndexedDB for fast, structured storage with indexes +

+
+
+

2. Fallback: Spark KV

+

+ If IndexedDB fails or is unavailable, Spark KV is used automatically +

+
+
+

3. Sync Both

+

+ Data is kept in sync between both storage systems for redundancy +

+
+
+ +
+

Code Example:

+ 
+              {`import { useStorage } from '@/hooks/use-storage'
+
+// Replaces useKV from Spark
+const [todos, setTodos] = useStorage('todos', [])
+
+// Use functional updates for safety
+setTodos((current) => [...current, newTodo])`}

Storage Management

+

+ Manage your local database and sync with cloud storage +

+
+ + + + + + Storage Information + + + This application uses IndexedDB as the primary local database, with Spark KV as a + fallback/sync option + + + +
+ +
+ + {stats && ( +
+ + + + + IndexedDB (Primary) + + + +
+ {stats.indexedDBCount} + items +
+ + Active + + + + + + + + + Spark KV (Fallback) + + + +
+ {stats.sparkKVCount} + items +
+ + Backup + + + +
+ )} + + + + + + + + Data Migration + + + Migrate existing data from Spark KV to IndexedDB for improved performance + + + + {isMigrating && ( +
+ +

+ Migrating data... {migrationProgress}% +

+
+ )} + + + +

+ This will copy all data from Spark KV into IndexedDB. Your Spark KV data will remain + unchanged. +

+ + + + + + + + Backup & Sync + + Sync IndexedDB data back to Spark KV as a backup + + + + +

+ This will update Spark KV with your current IndexedDB data. Useful for creating backups + or syncing across devices. +
