Blazor.Avatar 1.0.3

Blazor Avatar

This Blazor library provides components that render avatar. Currently this library only supports initial avatar.

This library has been tested only with Blazor WebAssembly.

Install

Install package from Nuget.

dotnet add package Blazor.Avatar --version <latest-version>

Register Blazor.Avatar dependencies by calling AddAvatarComponents() in Program.cs.

using Blazor.Avatar;

var builder = WebAssemblyHostBuilder.CreateDefault(args);
builder.RootComponents.Add<App>("#app");
builder.RootComponents.Add<HeadOutlet>("head::after");

builder.Services
  .AddAvatarComponents()
  .AddScoped(sp => new HttpClient { BaseAddress = new Uri(builder.HostEnvironment.BaseAddress) });

await builder.Build().RunAsync();

Load the dotnet-callback.js script by adding the line below in your wwwroot/index.html file.

<script type="module" src="_content/Blazor.Avatar/js/dotnet-callback.js"></script>

The reason this script is needed because some components can accept C# callback (like Func<> or Action<>), and this script helps serialize these callbacks to JS callbacks.

Usage

You can clone this repo and run the samples/Blazor.Avatar.Samples.WebAssembly project to see how the avatars are generated.

Initial Avatar

Use the InitialAvatar component in your Razor file.

@page "/"
@using Blazor.Avatar.Components.InitialAvatarComponent

<p>Render initial avatar with random color.</p>
<InitialAvatar FirstName="Aaron"
               LastName="Doe" />

<p>Render initial avatar with specify color and size.</p>
<InitialAvatar FirstName="Jane"
               LastName="Smith"
               FillColor="green"
               Size=100 />

<p>
  Render initial avatar with specify style. Note that
  specifying <b>Style="border-radius: 50%; width: 80px; height: 60px"</b>
  will override the <b>Size</b> parameter.
</p>
<InitialAvatar FirstName="gavin"
               LastName="baker"
               Size=150
               Style="border-radius: 50%" />

The above Razor code will be rendered like this:

Identicon Avatar

This is pretty much a wrapper of this JS library: https://github.com/laurentpayot/minidenticons. This library is currently using version 4.2.1 of this JS minidenticons library.
