Slickflow

.NET/.NETCore Workflow Engine With Full Source Code

  1. .NET, .NET CORE version both supported
    Slickflow is an open source project based on .NET Framework 4.5, .NET CORE 2; It's easy to use engine product into cross platform applilcation.
  2. BPMN graphic style process diagram
    Slickflow is using BPMN natation to descript process diagram, the Slickflow designer is HTML5 graph editor and user friendly to business process communicaiton and business analysis.
  3. High performance with Dapper.NET library
    Dapper is a simple object mapper for .NET and own the title of King of Micro ORM in terms of speed and is virtually as fast as using a raw ADO.NET data reader. An ORM is an Object Relational Mapper, which is responsible for mapping between database and programming language. (Ref: https://dapper-tutorial.net/dapper)
  4. Multiple database supported
    Slickflow supports SQLSERVER, ORACLE, MySQL and other database, it implemented by Dapper.NET extension library. The .net core version using EF core to support different database products.
  5. Workflow patterns supported
    Wokflow Pattern
    1). Sequence
    the most frequently process pattern
    2). Split/Merge
    support and/or gateway such as and/or split, and/or join, together with condition variables on the transition
    3). Sub-process
    in the main process, a sub process node can start a new process life cycle.
    4). Multi-instance
    muptile performers processing a task together by multiple task instances. All performer both compete their task, then the process can be continued on. There are sequence and parallel pattern, and the percentage or count parameters can be set on it to ensue when can go to next step.
    Muliple Instance Pattern
    5). Event interoperation
    process instance and activity instance event delegation service, such as process/activity start, execute and complete.
    6). Timer
    integrated with HangFire library, and with CRON expression supported
    7). Email
    todo or overdue taks email notification
    8). Withdraw
    withdraw the task after just sent out to next step users.
    9). Sendback
    send back to previous step user, becuase some exceptions.
    10). Resend
    combined after sendback and re-send the task to origianl sendback users.
    11). Reverse
    reverse the process instance alive when completed them.
    12). Jump
    jump the process over by serveral steps forward or backward.

6. Process Version
the process has version property to upgrade a new definition due to business process changed.
7. XML Cache
the runtime instance use cache to keep xml process diagram by an expired duration.
8. Sequence Process Code Style
0). Model

//create a simple sequence process diagram by hand code rather than a HTML designer  
var pmb = ProcessModelBuilder.CreateProcess("simple-process-name", "simple-process-code");
var process = pmb.Start("Start")
	.Task("Task1")
	.Task("Task2")
	.End("End")
	.Store();       

simple sequence diagram

1). Start

//start a new process instance
IWorkflowService wfService = new WorkflowService();
var wfResult = wfService.CreateRunner("10", "jack")
            .UseApp("DS-100", "Book-Order", "DS-100-LX")
            .UseProcess("PriceProcessCode")
            .Start();

2). Run

//run a process instance to next step
IWorkflowService wfService = new WorkflowService();
var wfResult = wfService.CreateRunner("10", "jack")
            .UseApp("DS-100", "Book-Order", "DS-100-LX")
            .UseProcess("PriceProcessCode")
            .NextStepInt("20", "Alice")
            .Run();

3). Withdraw

//Withdraw a activity instance to previous step
IWorkflowService wfService = new WorkflowService();
var wfResult = wfService.CreateRunner("10", "Jack")
            .UseApp("DS-100", "Book-Order", "DS-100-LX")
            .UseProcess("PriceProcessCode")
            .OnTask(id)             //TaskID
            .Withdraw();

4). SendBack

//Sendback a activity instance to previous step
IWorkflowService wfService = new WorkflowService();
var wfResult = wfService.CreateRunner("20", "Alice")
            .UseApp("DS-100", "Book-Order", "DS-100-LX")
            .UseProcess("PriceProcessCode")
            .PrevStepInt()
            .OnTask(id)             //TaskID
            .SendBack();

WebDemo, MvcDemo and WinformDemo project are domonstated for different type enterprise information system.
10. Target
Slickflow is very suitable for software teams or companies who want to integrat workflow engine into their products.
11. Suggestions
