How can I get npm start at a different directory?

Question

I usually cd into the app directory and then run npm start.

It is my feeling that there ought to be some way to run npm start

Answer 1

This one-liner should work too:

(cd /path/to/your/app && npm start)

Note that the current directory will be changed to /path/to/your/app after executing this command. To preserve the working directory:

(cd /path/to/your/app && npm start && cd -)

I used this solution because a program configuration file I was editing back then didn't support specifying command line arguments.
