检查nodejs是否在屏幕上运行

Question

I have a few nodejs processes running in different screens on a ubunutu-server. If a process in one of these screens crashed I'd like to have a script which automatically restarts the node script in the background. I always get solutions only checking if node is installed... is there a way to check and solve this?

Answer 1

You could write a simple loop that starts whatever script you need, in this case npm start :

while true
do
    npm start
done

You can add an & at the end if you need to.
