Frank.PulseFlow.Logging 2.0.8-preview

Frank.PulseFlow.Logging

This library provides a simple logger for use in .NET applications. It uses the Microsoft.Extensions.Logging library backed by Frank.PulseFlow for logging. It will log to the console by default, but can add one or more IFlow's to do whatever you want with the log messages. A common use case is to log to a file or a database, and because Frank.PulseFlow is thread-safe, you can do so without worrying about concurrency issues like file locks, or the overhead of waiting for a lock.

Usage

using Frank.PulseFlow.Logging;

public class Program
{
    public static async Task Main(string[] args)
    {
        var builder = new HostBuilder()
        .ConfigureLogging((hostContext, logging) =>
        {
            logging.AddPulseFlow();
        })
        .ConfigureServices((hostContext, services) =>
        {
            services.AddPulseFlow<FileLoggerFlow>();
        });
        .Build();
        
        await builder.RunAsync();
    }
}

public class FileLoggerFlow(IOptions<FileLoggerSettings> options) : IFlow
{
    private readonly FileLoggerSettings _settings = options.Value;
    
    public async Task HandleAsync(IPulse pulse, CancellationToken cancellationToken)
    {
        var thing = pulse as LogPulse;
        await File.AppendAllTextAsync(_settings.LogPath, thing! + Environment.NewLine, cancellationToken);
    }

    public bool CanHandle(Type pulseType) => pulseType == typeof(LogPulse);
}

public class FileLoggerSettings
{
    public string LogPath { get; set; } = "../../../../logs.log";
}

Configuration

The AddPulseFlow method has a few overloads that allow you to configure the logger. The default configuration is to log to the console, but you can add one or more IFlow's to the logger to do whatever you want with the log messages. A common use case is to log to a file or a database, and because Frank.PulseFlow is thread-safe, you can do so without worrying about concurrency issues like file locks, or the overhead of waiting for a lock.
