SingleLineConsoleLogger

Why?

Calling Console.WriteLine is slow. It is a blocking call and can cause performance issues if you are logging a lot of messages. This logger will print out all log messages on a single line and is much, much faster.

Alternatives: Some logging libraries such as NLog and Serilog implement asynchronous logging in a similar fashion.

Usage

You can add it to the service collection like this:

services.AddSingleLineConsoleLogger();

You might also consider removing other loggers. Here are some examples of how to do that:

services.AddLogging(builder =>
{
    builder.ClearProviders();
    builder.Services.AddSingleLineConsoleLogger();
});

var host = Host.CreateDefaultBuilder(args)
    .ConfigureLogging(logging =>
    {
        logging.ClearProviders();
        logging.Services.AddSingleLineConsoleLogger();
    })
    .Build();

Configuration

The following configuration options are available:

• LOG_LEVEL: The minimum log level to log. Default is Information. These are the same as the Microsoft.Extensions.Logging.LogLevel enum values.

• LOG_WITH_COLORS: If set to true, the logger will use colors. Default is true.
