storage's Introduction

Blazor Extensions

Blazor Extensions are a set of packages with the goal of adding useful things to Blazor.

Blazor Extensions Storage

This package wraps HTML5 Storage APIs. Both Session and Local storage types are supported.

Sample configuration

Setup

The following snippet shows how to setup the storage wrapper by registering it for dependency injection in the Startup.cs of the application.

public void ConfigureServices(IServiceCollection services)
{
    // Add Blazor.Extensions.Storage
    // Both SessionStorage and LocalStorage are registered
    services.AddStorage();
}

Usage

The following snippet shows how to consume the storage API in a Blazor component.

@inject SessionStorage sessionStorage
@inject LocalStorage localStorage

@functions {
  protected override async Task OnInitAsync()
  {
        var key = "forecasts";
        await sessionStorage.SetItem<WeatherForecast[]>(key, forecasts);
        await localStorage.SetItem<WeatherForecast[]>(key, forecasts);
        var fromSession = await sessionStorage.GetItem<WeatherForecast[]>(key);
        var fromLocal = await localStorage.GetItem<WeatherForecast[]>(key);
  }
}

If you want to consume it outside of a cshtml based component, then you can use the Inject attribute to inject it into the class.

[Inject]
protected SessionStorage sessionStorage;

[Inject]
protected LocalStorage localStorage;

public Task LogSomething()
{
        var key = "forecasts";
        await sessionStorage.SetItem<WeatherForecast[]>(key, forecasts);
        await localStorage.SetItem<WeatherForecast[]>(key, forecasts);
        var fromSession = await sessionStorage.GetItem<WeatherForecast[]>(key);
        var fromLocal = await localStorage.GetItem<WeatherForecast[]>(key);
}
