Hangfire Recurring Job

This document explains how to implement a recurring job with hangfire

Create the application Job​

Proceed like a DelegatedJob : Delegate job to worker Do not do the "Call the job" step.

Add your Task CRON​

Calculate the CRON​

You can use the site https://crontab.cronhub.io/ to calculate the cron.

Complete the Tasks parameters​

Edit your DeployDB/appsetting.json ex:

  "Tasks": {
    "WakeUp": {
      "CRON": "0 6-17 * * *"
    },
    "SynchronizeUser": {
      "CRON": "0 6 * * *"
    }
  },

Record the cron at db deployment :​

Edit your DeployDB/Program.cs

    services.AddHangfire(config =>
    {
        config.UseSqlServerStorage(configuration.GetConnectionString("BIADemoDatabase"));
        string projectName = configuration["Project:Name"];

        // Initialize here the recurring jobs
        RecurringJob.AddOrUpdate<WakeUpTask>($"{projectName}.{typeof(WakeUpTask).Name}", t => t.Run(), configuration["Tasks:WakeUp:CRON"]);
        RecurringJob.AddOrUpdate<SynchronizeUserTask>($"{projectName}.{typeof(SynchronizeUserTask).Name}", t => t.Run(), configuration["Tasks:SynchronizeUser:CRON"]);
    });
