我怎样才能在 package.json 中有多个入口点？

Question

I want to be able to run different commands with npm:

"scripts": {
  "v1": "node v1.js",
  "v2": "node v2.js"
}

with something like npm start v1 or npm start v2 , but these commands do not run the correct Node command.

Answer 1

The alternative would be to have a wrapper index.js or similar which runs the correct version based off the argument supplied to npm start

You can access an array of arguments using process.argv , and those values should be available whether you use npm start or node./index.js

Answer 2

Use npm run :

npm run v1

or

npm run v2

To add extra parameters add -- :

npm run v1 -- -param_one 1 --param2 2

Which is the equivalent of:

node v1.js -param_one 1 --param2 2
