You could use

screen -d -m -S screen.npmStart npm start

This opens a detached screen with name "screen.npmStart" and executes npm start in that screen.

Use screen -list to show the available screen sessions.

Execute the following command in your post build action to be sure the screen is killed after your main job has finished.

screen -S screen.npmStart -X quit || true
