Slickflow.Engine 2.3.0

Slickflow

Current Version:NET8

A Quick Design and Testing Demo:

Quick Start Tutorial for Designer Project:
1). In the command console, using the command npm install to download the node package.

please notice to run the command, the directory location is in the ClientApp path of the sfd project.

2). Set up the sfdapi project which is an asp.net webapi type project.(IIS is a choice)

3). Setting webapi variable in the kcofnig.js file

kconfig.webApiUrl = "http://localhost/sfdapic/" //your sfd webapi backend service url

4). In the command console, using the command npm run dev to the the project

5). Access the web project in the browser by

**http://localhost:5000**

.NET/.NETCore Workflow Engine With Full Source Code

1. .NET, .NET CORE version both supported
   Slickflow is an open-source project based on .NET6; It's easy to use engine product into the cross-platform application.
2. BPMN graphic style process diagram
   Slickflow is using BPMN2 notation to describe process diagram, the Slickflow designer is HTML5 graph editor and user-friendly to business process communication and business analysis.
3. High performance with Dapper.NET library
   Dapper is a simple object mapper for .NET and owns 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 databases supported
   Slickflow supports SQLSERVER, ORACLE, MySQL and another database, it implemented by the Dapper.NET extension library. The .net core version using EF core to support different database products.
5. Workflow patterns supported
   
   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 subprocess node can start a new process life cycle.
   4). Multi-instance
   multiple performers processing a task together by multiple task instances. All performers both compete for 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 the next step.
   
   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 tasks email notification
   8). Withdraw
   withdraw the task after just sent out to next step users.
   9). Sendback
   send back to the previous step user, because of some exceptions.
   10). Resend
   combined after sendback and re-send the task to original sendback users.
   11). Reverse
   reverse the process instance alive when completed.
   12). Jump
   jump the process over by several steps forward or backward.
   13). MessageQueue(RabbitMQ)
   message publishing and subscribing to implement message throwing and catching.

6. Process Version
the process has version property to upgrade a new definition due to the business process changed.
7. XML Cache
the runtime instance use cache to keep the 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();       

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();

9. Rich demo projects
WebDemo, MvcDemo, and WinformDemo project are demonstrated for a different type of enterprise information systems.
10. Target
Slickflow is very suitable for software teams or companies who want to integrate workflow engine into their products.
11. Suggestions
Slickflow is suggested to give programmers a flexible way to integrate workflow engine components into their products or customer projects. The programmers can write their own code segments based on the engine component.
