Hangfire.Console

Inspired by AppVeyor, Hangfire.Console provides a console-like logging experience for your jobs.

Features

Provider-agnostic: (allegedly) works with any job storage provider (currently tested with SqlServer and MongoDB).
100% Safe: no Hangfire-managed data (e.g. jobs, states) is ever updated, hence there's no risk to corrupt it.
With Live Updates: new messages will appear as they're logged, as if you're looking at real console.
(blah-blah-blah)

Setup

In .NET Core's Startup.cs:

public void ConfigureServices(IServiceCollection services)
{
    services.AddHangfire(config =>
    {
        config.UseSqlServerStorage("connectionSting");
        config.UseConsole();
    });
}

Otherwise,

GlobalConfiguration.Configuration
    .UseSqlServerStorage("connectionSting")
    .UseConsole();

NOTE: If you have Dashboard and Server running separately, you'll need to call UseConsole() on both.

Additional options

As usual, you may provide additional options for UseConsole() method.

Here's what you can configure:

ExpireIn – time to keep console sessions (default: 24 hours)
FollowJobRetentionPolicy – expire all console sessions along with parent job (default: true)
PollInterval – poll interval for live updates, ms (default: 1000)
BackgroundColor – console background color (default: #0d3163)
TextColor – console default text color (default: #ffffff)
TimestampColor – timestamp text color (default: #00aad7)

Log

Hangfire.Console provides extension methods on PerformContext object, hence you'll need to add it as a job argument.

NOTE: Like IJobCancellationToken, PerformContext is a special argument type which Hangfire will substitute automatically. You should pass null when enqueuing a job.

Now you can write to console:

public void TaskMethod(PerformContext context)
{
    context.WriteLine("Hello, world!");
}

Like with System.Console, you can specify text color for your messages:

public void TaskMethod(PerformContext context)
{
    context.SetTextColor(ConsoleTextColor.Red);
    context.WriteLine("Error!");
    context.ResetTextColor();
}

Progress bars

Version 1.1.0 adds support for inline progress bars:

public void TaskMethod(PerformContext context)
{
    // create progress bar
    var progress = context.WriteProgressBar();
    
    // update value for previously created progress bar
    progress.SetValue(100);
}

You can create multiple progress bars and update them separately.

By default, progress bar is initialized with value 0. You can specify initial value and progress bar color as optional arguments for WriteProgressBar().

Enumeration progress

To easily track progress of enumeration over a collection in a for-each loop, library adds an extension method WithProgress:

public void TaskMethod(PerformContext context)
{
    var bar = context.WriteProgressBar();
    
    foreach (var item in collection.WithProgress(bar))
    {
        // do work
    }
}

It will automatically update progress bar during enumeration, and will set progress to 100% if for-each loop was interrupted with a break instruction.

NOTE: If the number of items in the collection cannot be determined automatically (e.g. collection doesn't implement ICollection/ICollection<T>/IReadOnlyCollection<T>, you'll need to pass additional argument count to the extension method).
