Answer 1

You should use "postinstall" in scripts.

Answer 2

It's almost certainly best not to have a post-install step at all. What you really want to do is to build the project before it is published , and then publish the built version to NPM (assuming that's what you are trying to do). In that case, you might use a prepublish script:

// package.json

"scripts": {
  "build": "babel src -d build",
  "prepublish": "npm run build"
}

And make sure the built files are included in your files array :

// package.json

"files": ["build"]

Or that your source files are excluded in your .npmignore :

// .npmignore

/src/

If you really do need a post-install step for some reason, use a postinstall script:

// package.json

"scripts": {
  "build": "babel src -d build",
  "postinstall": "npm run build"
}

But I can't think of a use-case where this would be a good idea.
