Soenneker.Serilog.Sinks.Browser.Blazor

A Serilog sink for logging within the Blazor client-side environment

An example demo app has been added to the solution.

?? Installation

1. Install Required NuGet Packages

dotnet add package Soenneker.Serilog.Sinks.Browser.Blazor

2. Configure Logging in Program.cs

An example:

using System;
using System.Threading.Tasks;
using Microsoft.AspNetCore.Components.Web;
using Microsoft.AspNetCore.Components.WebAssembly.Hosting;
using Microsoft.Extensions.DependencyInjection;
using Microsoft.Extensions.Logging;
using Microsoft.JSInterop;
using Serilog;
using Serilog.Debugging;
using Serilog.Events;
using Soenneker.Serilog.Sinks.Browser.Blazor.Registrars;

public class Program
{
 public static async Task Main(string[] args)
 {
 try
 {
 var builder = WebAssemblyHostBuilder.CreateDefault(args);

 ConfigureLogging(builder.Services);

 builder.RootComponents.Add<App>("#app");
 builder.RootComponents.Add<HeadOutlet>("head::after");

 WebAssemblyHost host = builder.Build();

 AddBlazorConsoleLogger(host);

 await host.RunAsync();
 }
 catch (Exception e)
 {
 Log.Error(e, "Stopped program because of exception");
 throw;
 }
 finally
 {
 await Log.CloseAndFlushAsync();
 }
 }

 private static IServiceCollection ConfigureLogging(IServiceCollection services)
 {
 SelfLog.Enable(m => Console.Error.WriteLine(m));

 services.AddLogging(builder =>
 {
 builder.ClearProviders();
 builder.AddSerilog(dispose: false);
 });

 return services;
 }

 private static WebAssemblyHost AddBlazorConsoleLogger(WebAssemblyHost host)
 {
 var jsRuntime = host.Services.GetRequiredService<IJSRuntime>();

 var loggerConfig = new LoggerConfiguration();

 loggerConfig.WriteTo.BlazorConsole(jsRuntime: jsRuntime);

 Log.Logger = loggerConfig.CreateLogger();

 return host;
 }
}

How It Works

• ConfigureLogging(IServiceCollection services)
  • Enables Serilog's self-logging to capture any internal errors.
  • Registers Serilog as the primary logging provider.
• SetGlobalLogger(WebAssemblyHost host)
  • Initializes the BlazorConsole sink to log messages directly in the browser's developer console.

?? Usage

Once you have installed and configured Serilog with the BlazorConsole sink, you can start logging messages in your Blazor components.

Injecting the Logger

In your Blazor component (.razor file), inject the ILogger<T> service:

@page "/"
@using Microsoft.Extensions.Logging

@inject ILogger<Index> Logger

<button @onclick="Click">Click</button>

@code {
 public void Click()
 {
 Logger.LogInformation("Testing information log");
 }
}
