Is there a way to pass command line arguments to an npm 'pre' script or to a script which runs multiple commands?
Assuming a simple script mySexyScript.js that just logs out the process.argv :
console.log(process.argv);
This works
With an npm script:
...
"scripts": {
....
"sexyscript": "node mySexyScript.js"
....
}
...
running:
npm run sexyscript -- --foo=bar
the arguments are logged to the console as expected.
'pre' script - This doesn't work
With an npm script:
...
"scripts": {
....
"presexyscript": "node mySexyScript.js"
"sexyscript": "node mySuperSexyScript.js"
....
}
...
running:
npm run sexyscript -- --foo=bar
the arguments are not passed to mySexyScript and they are not logged
Multiple commands - This also doesn't work
With an npm script:
...
"scripts": {
....
"sexyscript": "node mySexyScript.js && node mySuperSexyScript.js"
....
}
...
running:
npm run sexyscript -- --foo=bar
the arguments are not passed to mySexyScript and they are not logged
回答1:
There is no way to pass args in the way that you are describing.
Assuming a package.json:
...
"scripts": {
....
"somescript": "node one.js && node two.js"
....
}
...
Running:
npm run somescript -- --foo=bar
basically just runs
node one.js && node two.js --foo=bar
on the default system shell (usually bash or cmd.exe).
npm doesn't actually know anything about shell operators (i.e. &&), so it can't pass args to both scripts.
