VersaTul.Logger 1.0.9

VersaTul Logger

VersaTul Logger is a project that provides common functionality for different types of loggers, such as FileLogger, MailLogger, and WebLogger. It also provides interfaces to ensure consistency across all logger apps.

Installation

You can install VersaTul Logger using NuGet:

PM> NuGet\Install-Package VersaTul.Logger -Version latest

Usage

To use VersaTul Logger, you need to implement the ILogger interface, which represents the functionality provided by a logger. You also need to implement the ILogParser interface, which represents the parsing functionality to use for parsing logged data.

Here is an example of how to create and use a DatabaseLogger class that implements both interfaces:

// Create a project specific interface
public interface IDatabaseLogger : ILogger
{
  // project specific methods can be added here...
}

// Implementing interface
public class DatabaseLogger: IDatabaseLogger
{
  private readonly ILogParser logParser;

  public DatabaseLogger(ILogParser logParser)
  {
    this.logParser = logParser;
  }

  // interface methods...
  public void Log(LogInfo logInfo) => LogAsync(logInfo)
    .GetAwaiter()
    .GetResult();

  public void Log(Exception exception) => LogAsync(exception)
    .GetAwaiter()
    .GetResult();

  public void Log(LogInfo logInfo, Exception exception) => LogAsync(logInfo, exception)
    .GetAwaiter()
    .GetResult();

  public async Task LogAsync(Exception exception) => await LogAsync(new LogInfo(LogLevel.Error, string.Empty, exception.Message), exception);

  public async Task LogAsync(LogInfo logInfo) => await LogAsync(logInfo, null);

  public async Task LogAsync(LogInfo logInfo, Exception exception)
  {
    var message = logParser.Parse(logInfo, exception, ParseFormat.Tab);
    // send message to database here...
  }
}

// Configure the container using AutoFac Module
public class AppModule : Module
{
  protected override void Load(ContainerBuilder builder)
  {
    // Registering logger to container
    builder
      .RegisterType<DatabaseLogger>()
      .As<IDatabaseLogger>()
      .As<ILogger>()
      .SingleInstance();
  }
}

// Usage catching and logging exceptions...
public abstract class BaseController : Controller
{
  private readonly ILogger logger;

  protected BaseController(ILogger logger)
  {
    this.logger = logger;
  }

  protected IActionResult FaultHandler(Func<IActionResult> codeToExecute)
  {
    try
    {
      return codeToExecute();
    }
    catch (Exception ex)
    {
      logger.Log(ex);
      return BadRequest();
    }
  }
}
