Hello,
i got a strange error with Ionic2 and Ionic serve.
I start "ionic serve -cs"
Then I am working on my files and save them (Webstorm) and usually “ionic serve” automaticly detects as soon as a file has changed and restarts the “lite server”
but now it does not work 
Info: I have 3 projects and it is only happening in one project.
Maybe someone could help me?
Thank you.
Check the terminal with the server running. Chances are you have a typescript error that is preventing it from building.
Sometimes ionic serve not syncing files that created after the ionic serve command so you just need to re-run this command and it will sync and refresh after every file change
I too am facing the same problem. Ionic serve is not refreshing the changes. The npm terminal shows watch ready and then template update started …
But nothing happens after that. I have to stop the command and retype “ionic serve” to see my changes.
