Bug: babel.generated is not a function

[Alexander]

I try to follow docs from this section https://github.com/rollup/rollup-plugin-babel#running-babel-on-the-generated-code

But babel.generated not exists:

rollup.config.js

// ...
import babel from 'rollup-plugin-babel';

const plugins = [
  // ...
  babel.generated({
    presets: ['@babel/env']
  }),
  // ...
];

$ rollup -c -w

package.json:

  // ...
  "devDependencies": {
    "rollup": "^1.27.5",
    "rollup-plugin-babel": "^4.3.3",
     // ...
  }
}

I ran into the same trap.
This is a rather new functionality (7 hours old) and there is just no new release on npm... yet.

[Mateusz Burzyński]

Yes, sorry for that - I guess we should add an unreleased label to this for the time being. I'm going to move things forward to get this released as soon as possible, but it might take a few days.

[Troy Rhinehart]

Any workaround to this? Just ran into this as well, can an alpha release be made or something in the meantime?

[Mateusz Burzyński]

@gingur I'm going to cut a new alpha v5 release this week so stay tuned.

[Rúnar Berg Baugsson Sigríðarson]

It looks like v5.0.0-alpha.0 was released on top of an 11 month old comment 😕

[James Pearce]

Yep,

$ npm list | grep rollup-plugin-babel
  rollup-plugin-babel@5.0.0-alpha.0

Still gives

[!] TypeError: babel.generated is not a function

[Tim Zech]

As you can see here https://www.npmjs.com/package/rollup-plugin-babel/v/5.0.0-alpha.0 this version is a year old and has nothing to do with the current implementation on master.

[Mateusz Burzyński]

I've just published new rollup-plugin-babel@next (5.0.0-alpha.1) with this feature included - please give it a try.
