I have a simple web server application running with oak. When I use the command denon run --allow-net app.ts the auto reload successfully kill the webserver on each reload.

But when I use the denon dev command and using the denon.json file, the application isn't killed on each reload. For example, if I run the webserver on 8080 port, then change it to 8081 then save, I end up with 2 webserver. If I doesn't change the port between two save, I hand up with an error saying one app already use this port.

Here is my denon.json file

And my app.ts file
