Raygun for Blazor Server

Raygun provider for Blazor Server.

Full usage instructions can be found in the Raygun.Blazor package page.

Installation

Install the packages Raygun.Blazor and Raygun.Blazor.Server from NuGet.

Setup

Add a scoped RaygunBlazorClient by calling to UseRaygunBlazor() with your WebApplication builder.

var builder = WebApplication.CreateBuilder(args); ... builder.UseRaygunBlazor();

Accessing RaygunBlazorClient

You can access the RaygunBlazorClient using @inject in your code:

@inject RaygunBlazorClient RaygunClient ... RaygunClient.RecordExceptionAsync(...)

Capturing unhandled exceptions

Use RaygunErrorBoundary to wrap components and capture unhandled exceptions automatically.

Note: You have to set @rendermode="InteractiveServer" in your HeadOutlet and Routes component to enable error capturing, as explained in Handle errors in ASP.NET Core Blazor apps

For example, in your MainLayout.razor:

@using Raygun.Blazor.Server.Controls ... <article class="content px-4"> <RaygunErrorBoundary> @Body </RaygunErrorBoundary> </article>

You can set ShowExceptionsUI="true to display a custom error message:

<RaygunErrorBoundary ShowExceptionUI="true"> <ChildContent> @Body </ChildContent> <ErrorContent> <p class="errorUI">👾 Error captured by Raygun!</p> </ErrorContent> </RaygunErrorBoundary>
