In node package.json, invoke script from another script with extra parameter, in this case add mocha watcher
This can be done in npm@2.1.17. You don't specify your OS and the version of npm that you are using, but unless you have done something to update it, you are probably running npm@1.4.28 which does not support the syntax below.
On Linux or OSX you can update npm with sudo npm install -g npm@latest. See https://github.com/npm/npm/wiki/Troubleshooting#try-the-latest-stable-version-of-npm for a guide to updating npm on all platforms.
You should be able to do this by passing an additional argument to your script:
"scripts": { "test": "mocha --compilers coffee:coffee-script/register --recursive -R list", "watch": "npm run test -- -w"}I verified this using the following, simplified package.json:
{ "scripts": { "a": "ls", "b": "npm run a -- -l" }}Output:
$ npm run a> @ a /Users/smikes/src/github/foo> lspackage.json$ npm run b> @ b /Users/smikes/src/github/foo> npm run a -- -l> @ a /Users/smikes/src/github/foo> ls -ltotal 8-rw-r--r-- 1 smikes staff 55 4 Jan 05:34 package.json$
