node.js - babel directive how to skip translation of certain files?

Question

How can the babel command skip the translation of certain files?
Currently using:

babel src -s -D -d dist

.babelrc

{
  "presets": [
    "es2015",
    "stage-2"
  ],
  "plugins": [
      ["transform-runtime", {
        "polyfill": false,
        "regenerator": true
      }]
  ]
}

All files in src will be translated and saved to dist
Now you need to save the src/app files directly to dist without translation, while other files in src will still be translated.
Thanks! ! !

Answer 1

I have a question, why don’t you take a look babel --help

Option	Default	Description
-i, --ignore [regex]	node_modules	Ignore all files that match this regex when using the require hook

babel src -s -D -d dist --ignore src/app

Answer 2

You can use --ignore或者--copy-fileparameters:

babel src -s -d dist --ignore src/app/*.js

--copy-fileI haven’t used it specifically, you can refer to
