Incredibly easy way to perform fire-and-forget, delayed and recurring jobs inside ASP.NET applications. CPU and I/O intensive, long-running and short-running jobs are supported. No Windows Service / Task Scheduler required. Backed by Redis, SQL Server, SQL Azure or MSMQ.
Hangfire provides unified programming model to handle background tasks in a reliable way and run them on shared hosting, dedicated hosting or in cloud. You can start with a simple setup and grow computational power for background jobs with time for these scenarios:
- mass notifications/newsletter;
- batch import from xml, csv, json;
- creation of archives;
- firing off web hooks;
- deleting users;
- building different graphs;
- image/video processing;
- purge temporary files;
- recurring automated reports;
- database maintenance;
- …and so on.
Hangfire is a .NET Framework alternative to Resque, Sidekiq, delayed_job.
Installation
Hangfire is available as a NuGet package. So, install it using the NuGet Package Console window:
PM> Install-Package Hangfire
After install, update your existing OWIN Startup file with the following lines of code. If you do not have this class in your project or don't know what is it, please read the Quick start guide to learn about how to install Hangfire.
app.UseHangfire(config =>
{
config.UseSqlServerStorage("<connection string or its name>");
config.UseServer();
});
Usage
This is incomplete list of features, to see all of them, check the official site and the documentation.
Enqueued background jobs are being executed inside a dedicated worker pool threads as soon as possible, shortening your request processing time.
BackgroundJob.Enqueue(() => Console.WriteLine("Simple!"));
Scheduled background jobs are being executed only after given amount of time.
BackgroundJob.Schedule(() => Console.WriteLine("Reliable!"), TimeSpan.FromDays(7));
Recurring jobs were never been simpler, just call the following method to perform any kind of recurring task using the CRON expressions.
RecurringJob.AddOrUpdate(() => Console.WriteLine("Transparent!"), Cron.Daily);
Process them inside a web application…
You can process background tasks in any OWIN compatible application frameworks, including ASP.NET MVC, ASP.NET Web API, FubuMvc, Nancy, etc. Forget about AppDomain unloads, Web Garden & Web Farm issues – Hangfire is reliable for web applications from scratch, even on shared hosting.
app.UseHangfire(config => config.UseServer());
… or anywhere else
In console application, Windows Service, Azure Worker Role, etc.
var server = new BackgroundJobServer();
server.Start();
