A simple finite state machine (FSM) with workflow character where you define your workflows in code.
In code it looks like:
public class HolidayApprovalWorkflow : WorkflowDefinitionBase
{
public const string TYPE = "HolidayApprovalWorkflow";
public override string Type
{
get { return TYPE; }
}
public override List<Transition> Transitions
{
get
{
return new List<Transition>
{
new Transition {
State = "New",
Trigger = "Apply",
TargetState ="Applied",
CanMakeTransition = MeApplyingForHolidays
},
new Transition {
State = "Applied",
Trigger = "Approve",
TargetState ="Approved",
CanMakeTransition = BossIsApproving,
AfterTransition = ThankBossForApproving
},
new Transition {
State = "Applied",
Trigger = "Reject",
TargetState ="Rejected"
}
};
}
}
private bool MeApplyingForHolidays(TransitionContext context)
{
var holiday = context.GetInstance<Holiday>();
return holiday.Me == "Me";
}
private bool BossIsApproving(TransitionContext context)
{
var holiday = context.GetInstance<Holiday>();
return holiday.Boss == "NiceBoss";
}
private void ThankBossForApproving(TransitionContext context)
{
// SendMail("Thank you!!!");
}
}Assuming you downloaded the sources and opened the directory with VS Code you should be good to go! Ahh and of course you need dot.net core and node.js installed on your development environment.
- Open the integrated terminal in VS Code and type
dotnet build
That ensures you are able to build the dotnet related stuff!
- Hit "F5" and VS Code will do its magic! There are some VS Code tasks defined which will run the WebApi and open your default browser.
- In the terminal change to the directory
cd samples/WebClient
- Install all npm deps
npm install
- Run the application
npm run start
You should see now the login screen.
Happy poking!!
