Blazored LocalStorage

A library to provide access to local storage in Blazor applications

Build Status

Nuget

Installing

You can install from NuGet using the following command:

Install-Package Blazored.LocalStorage

Or via the Visual Studio package manger.

Setup

You will need to register the local storage services with the service collection in your startup.cs file.

public void ConfigureServices(IServiceCollection services)
{
    services.AddBlazoredLocalStorage();
}

Usage (Blazor WebAssembly)

To use Blazored.LocalStorage in Blazor WebAssembly, inject the ILocalStorageService per the example below.

@inject Blazored.LocalStorage.ILocalStorageService localStorage

@code {

    protected override async Task OnInitializedAsync()
    {
        await localStorage.SetItemAsync("name", "John Smith");
        var name = await localStorage.GetItemAsync<string>("name");
    }

}

With Blazor WebAssembly you also have the option of a synchronous API, if your use case requires it. You can swap the ILocalStorageService for ISyncStorageService which allows you to avoid use of async/await. For either interface, the method names are the same.

@inject Blazored.LocalStorage.ISyncStorageService localStorage

@code {

    protected override void OnInitialized()
    {
        localStorage.SetItem("name", "John Smith");
        var name = localStorage.GetItem<string>("name");
    }

}

Usage (Blazor Server)

NOTE: Due to pre-rendering in Blazor Server you can't perform any JS interop until the OnAfterRender lifecycle method.

@inject Blazored.LocalStorage.ILocalStorageService localStorage

@functions {

    protected override async Task OnAfterRenderAsync(bool firstRender)
    {
        await localStorage.SetItemAsync("name", "John Smith");
        var name = await localStorage.GetItemAsync<string>("name");
    }

}

The APIs available are:

  • asynchronous via ILocalStorageService:

    • SetItemAsync()
    • GetItemAsync()
    • RemoveItemAsync()
    • ClearAsync()
    • LengthAsync()
    • KeyAsync()
    • ContainsKeyAsync()
  • synchronous via ISyncStorageService (Synchronous methods are only available in Blazor WebAssembly):

    • SetItem()
    • GetItem()
    • RemoveItem()
    • Clear()
    • Length()
    • Key()
    • ContainsKey()

Note: Blazored.LocalStorage methods will handle the serialisation and de-serialisation of the data for you.
