### A Blazor utility library for managing IndexedDB

## Installation

```bash

dotnet add package Soenneker.Blazor.Utils.IndexedDb

```

## Setup

Register services in `Program.cs`:

```csharp

builder.Services.AddIndexedDbUtilAsScoped();

```

Inject the higher-level utility where you need it:

```csharp

@inject IIndexedDbUtil IndexedDb

```

## Usage

Initialize the package once before first use, ensure the store exists, then read/write values by `databaseName`, `storeName`, and `key`:

```csharp

await IndexedDb.Initialize();

const string databaseName = "app";

const string storeName = "settings";

const string key = "theme";

await IndexedDb.EnsureStore(databaseName, storeName);

await IndexedDb.Set(databaseName, storeName, key, "dark");

string? theme = await IndexedDb.Get(databaseName, storeName, key);

bool hasTheme = await IndexedDb.ContainsKey(databaseName, storeName, key);

int count = await IndexedDb.GetLength(databaseName, storeName);

```

You can also store typed objects; values are JSON-serialized by `IIndexedDbUtil`:

```csharp

public sealed record UserPreference(string Theme, bool SidebarCollapsed);

await IndexedDb.Set("app", "preferences", "user:1", new UserPreference("dark", true));

UserPreference? preference = await IndexedDb.Get("app", "preferences", "user:1");

```
