Easier mechanism to add babel-polyfill about neutrino HOT 10 CLOSED

Looking over your preset override, you can also use prepend for polyfill and avoid the deletions and re-additions:

module.exports = ({ config }) => {
  config.entry('index').prepend('babel-polyfill');
}

It's funny you brought this up, because at the moment I am adding babel-polyfill by default to the index entry. This will probably land in v5, but still wanted to address your question.

In addition to the approach you took to adding babel-polyfill, you can also import it directly from your entrypoint:

import 'babel-polyfill';
import React from 'react';
// ...

You can also add it from your package.json:

{
  "config": {
    "neutrino": {
      "entry": {
        "index": ["babel-polyfill"]
      }
    }
  }
}

Prepend solution looks great.

Out of curiosity, is this method documented? I do not see it in the documentation for webpack-chain. I do however see it in the src.

Oo, good find, looks like it's not documented. I'll fix that up.

Awesome. Thank you for the help and prompt replies!

hi, @eliperelman , thanks for your funny neutrino project. I am new to neutrino, 😂 I want to remove the babel-polyfill for the lastest chrome so that easy to debug the generator. But I saw that, the generator transform will be default? Any thought about that?

What is best way to add babel-polyfill in Neutrino v8 ?

from neutrino.

@eliperelman solution works well for v8, here you have my .neutrinorc.js:

module.exports = {
  use: [
    '@neutrinojs/standardjs',
    ({ config }) => config.entry('index').prepend('babel-polyfill'),  // you need this line
    '@neutrinojs/node',
    '@neutrinojs/jest'
  ]
}

This solution add 2 more files in build for the react-components preset
