Hangfire Background Delayed Jobs — Console Application
In one of my previous article, I wrote about Hangfire Recurring Job.
In this article, I am going to explain the working of Hangfire Delayed Jobs
Hangfire is an open-source framework that helps you to create, process and manage your background jobs, i.e. operations you don’t want to put in your request processing pipeline:
Hangfire supports different types of background jobs:
Fire-and-forget, Background Process, Delayed, Continuations, Batches, Batch Continuations
Delayed jobs are executed only once too, but not immediately — only after the specified time interval.
Install the Hangfire package using NuGet
PM> Install-Package HangfireIn the App.config, add the connecting string to get Hangfire Job Storage as:
<add name=”HangfireConnection” connectionString=”Data Source=GHANSHYAMS\SQLEXPRESS;Initial Catalog=Hangfire_Demo;Integrated Security=True;” providerName=”System.Data.SqlClient”/>
Now, install Topshelf package from NuGet and also some more packages like Microsoft.Owin.Host.HttpListener, Microsoft.Owin.Host.SystemWeb & Microsoft.Owin.Hosting
Add the Startup.cs class and configure the Hangfire dashboard.
Delayed Jobs
The Delayed Job structure consists of Method/Function to execute, Queue, Type, Delay Time Span
By default Hangfire processes Default queue, but you can also specify your own queue like:
Queue("feedback")]
public void SomeMethod() { }To begin processing queues, you need to update your BackgroundJobServer configuration.
Methods to Trigger by Hangfire
var options = new BackgroundJobServerOptions
{
Queues = new[] { "feedback", "default" }
};app.UseHangfireServer(options);
Method to Trigger
After all configurations are done, start the console application and open the below URL in browser as:
You can access Hangfire dashboard with “/hangfire”.
