You build node.js app with express v4.x then start your app by npm start. My question is how to stop the app? Is there npm stop?
If you've already tried ctrl + c
and it still doesn't work, you might want to try this. This has worked for me.
Run command-line as an Administrator. Then run the command below to find the processID (PID) you want to kill. Type your port number in
netstat -ano | findstr :
Then you execute this command after you have identified the PID.
taskkill /PID
