/* This is sample code for the following video: https://youtu.be/36p2-gr_iYk
 * The following NuGet packages are needed:

*/

using Hangfire;

var builder = WebApplication.CreateBuilder(args);

// Add Hangfire client and setup SQL Server connections
builder.Services.AddHangfire(options => {
    options.UseSqlServerStorage(@"SERVER=.\SqlExpress;TRUSTED_CONNECTION=yes;DATABASE=HangfireDemo");
});

// Add Hangfire server
builder.Services.AddHangfireServer(options => {
    options.SchedulePollingInterval = TimeSpan.FromSeconds(1);
});

var app = builder.Build();

// Enable dashboard UI at /hangfire
app.UseHangfireDashboard();
app.MapHangfireDashboard();

// Show homepage
app.MapGet("/", () => "Hello World!");

// Get job client from IoC/DI container
var scope = app.Services.CreateScope();
var jc = scope.ServiceProvider.GetRequiredService<IBackgroundJobClient>();

// Run ASAP
var j1 = jc.Enqueue(() => Console.WriteLine(">>>>> Fire and forget!"));

// Run delayed
var j2 = jc.Schedule(() => Console.WriteLine(">>>>> Scheduled job"), TimeSpan.FromSeconds(5));
jc.ContinueJobWith(j2, () => Console.WriteLine(">>>>> Continuation of Scheduled job."));

// Run repeatedly
// For explanation of the Cron expression see https://en.wikipedia.org/wiki/Cron#CRON_expression
RecurringJob.AddOrUpdate("MyRecurringJob", () => Console.WriteLine(">>>>> Recurring job"), "*/10 * * * * *");

// Run application
app.Run();
