Scheduled callbacks for your web applications
Revalee can simplify your web application's workflow when events are required AFTER the normal handling of a web request. You can write all of your scheduled activities in the same toolset and application as the rest of your web code. No more command line utilities or custom batch jobs.
Here are some common ways to utilize the power of scheduled callbacks:
- Sending reminder email messages.
- Running recurring automated reports.
- Scheduling daily maintenance functions.
- Expiring accounts or subscriptions.
- Canceling incomplete transactions.
- Consolidating multiple notification messages.
- Purging temporary files.
Revalee consists of a Windows service that stores and initiates the callbacks, plus a client API to schedule those callbacks. You will need to install both service and client to get started.
The Revalee service is available on Chocolatey. To perform a quick install, use:
The Revalee service can also be downloaded here or built from the source code.
The Revalee client library is available on NuGet. To include in a .NET 4.0+ project, use:
Alternatively for ASP.NET MVC projects targeting .NET 4.5+, a specialized Revalee client library is also available on NuGet. To install:
Callbacks can also be scheduled from any platform without the use of a client library by using the REST API.
Request a one-time web callback in 1 hour for id=123456
var callbackDelay = TimeSpan.FromHours(1.0); var callbackUri = new Uri("http://localhost/Home/Callback?id=123456"); Guid callbackId = RevaleeRegistrar.ScheduleCallback(callbackDelay, callbackUri);
Request a recurring web callback every night at 3:30 AM
var manifest = RecurringTasks.RecurringTaskModule.GetManifest(); var callbackUri = new Uri("http://localhost/Recurring/Nightly"); manifest.AddDailyTask(3, 30, callbackUri);
- Windows XP or later
- .NET Framework 4.0+ (only System, System.Core, System.Web assemblies are referenced)
The ASP.NET MVC client library requires .NET Framework 4.5+ and Microsoft ASP.NET MVC 5+.
