🎯 Usage

Register Services

using Msm.Workflow.Lib.Application;

// In Program.cs or Startup.cs
services.AddApplication();

Configure Custom Providers

services.AddApplication()
    .ConfigureWorkflow(options =>
    {
        // Customize UserProvider
        options.UseUserProvider<MyUserProvider>();
        
        // Customize ApproverResolver
        options.UseApproverResolver<MyApproverResolver>();
        
        // Customize CriteriaEvaluator
        options.UseCriteriaEvaluator<MyCriteriaEvaluator>();
    });

Use Services

public class MyController : ControllerBase
{
    private readonly IWorkflowProcessService _processService;
    private readonly IWorkflowInstanceService _instanceService;

    public MyController(
        IWorkflowProcessService processService,
        IWorkflowInstanceService instanceService)
    {
        _processService = processService;
        _instanceService = instanceService;
    }

    [HttpPost("create-process")]
    public async Task<IActionResult> CreateProcess(CreateWorkflowProcessDto dto)
    {
        var process = await _processService.CreateProcessAsync(dto);
        return Ok(process);
    }

    [HttpPost("trigger")]
    public async Task<IActionResult> TriggerWorkflow(string processCode, string objectId)
    {
        var instance = await _instanceService.CreateInstanceAsync(
            processCode: processCode,
            objectId: objectId,
            objectType: "PURCHASE_ORDER",
            submitterId: "user123"
        );
        return Ok(instance);
    }
}

Implement Custom Interfaces

// Custom UserProvider
public class MyUserProvider : IUserProvider
{
    public Task<UserInfo?> GetUserAsync(string userId, CancellationToken cancellationToken = default)
    {
        // Your implementation
    }
    
    // ... other methods
}

// Custom Action Handler
public class MySmsHandler : IWorkflowActionHandler
{
    public string ActionType => "SMS_ALERT";
    
    public Task ExecuteAsync(WorkflowAction action, CancellationToken cancellationToken = default)
    {
        // Your implementation
    }
}
