LMY.Workflow

lmy.workflow

LMY.workflow is a powerful workflow engine that simplifies simple and complex workflow problems.

LMY.workflow provides a simple and efficient way to develop workflows in your system.

Whether you are dealing with simple or complex workflows, LMY.workflow can handle it all.

it is built using .net 6

How To Use

1 - Include LMY.WorkFlow in your project.

2 - build your workflow configuration file (check workflow sample wf.config.json).

3 - add below to program.cs

builder.Services
.AddLMYWFEngineMSSQL()
.AddLMYWFEngine();

builder.UseLMYWFEngine(o =>
{
    o.WorkFlowsConfigFilePath = @"C:\wf.config.json";
    o.DBConnectionString = @"Server=.\SQLEXPRESS;Database=testdb;Integrated Security=SSPI;";
});

4 - once you have included the LMYEngine, you can now inject the ILMYWFEngine whenever you need it, making it available for use throughout your application

ILMYWFEngine lmyWFEngine;
public TestController(ILMYWFEngine _lmyWFEngine)
{
    lmyWFEngine= _lmyWFEngine;
}

5 - now you can start work flow like below

var result = lmyWFEngine.StartNew("LeaveRequestWF", "user1");
var LMYWFEngineRequestID = result.MethodResult;//started worklfow id

6 -you can get available transitions for specific workflow (you need to pass workflowid and current user groups )

var transitions =lmyWFEngine.GetAvailableTransitions("LeaveRequestWF", LMYWFEngineRequestID, "user1", new string[] { "DataEntry", "Leader" });

var LMYWFEngineRequestID = result.MethodResult;

7 - process taken transition

var moveNextResult = lmyWFEngine.MoveNext("LeaveRequestWF", LMYWFEngineRequestID, transitions.MethodResult[0].LMYWFEngineTransitionID, transitions.MethodResult[0].LMYWFEngineRequestVersionID, "user1", new string[] { "DataEntry", "Leader" }, true, "{you can include here whatever data you want}");

8 - you can get current user tasks (based on provided user groups)

int total = 0;

var tasks = lmyWFEngine.GetTasks("LeaveRequestWF", "user1", new string[] { "DataEntry", "Leader" }, 1, 10, out total);
