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
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 actions (transitions) for specific workflow (you need to pass workflowid and current user groups )
var transitions =lmyWFEngine.GetAvailableTransitions("LeaveRequestWF", LMYWFEngineRequestID, "user1", new string[] { "DataEntry", "Leader" });
7 - process taken action (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);
