How to set shell for npm run-scripts in Windows

Question

I'm running npm on Windows and would like to use & style parallel operations in run-scripts but running in parallel in cmd is kind of messy in my package.json file I'd like to write-

scripts: { "go": "cmd1 & cmd2"} 

but npm executes the script under cmd.exe which does not know about ; I could change this to scripts: { "go": "bats/bat1.bat") where bat1.bat is a cmd bat file that uses the windows style call or start commands to run commands in parallel. which works but gives me a script that only works on Windows.

It would be a lot simpler if I could get npm to run the script under a bash clone or cygwin.

I tried config: { "shell": "bash"} but that still ran cmd.exe

Is there any way to tell npm to run-scripts using a specific shell (not cmd.exe)?

Answer 1

Since npm 5.1

npm config set script-shell "C:\Program Files (x86)\git\bin\bash.exe"  

or (64bit installation)

npm config set script-shell "C:\Program Files\git\bin\bash.exe"

Note that you need to have git for windows installed.

You can revert it by running:

npm config delete script-shell
