Babel configuration docs does not mention configureBabelPresetEnv

[stollr]

In the encore docs about the Babel configuration is is explained how to use .configureBabel. But nothing is said about configureBabelPresetEnv.

Let's ask @WebMamba to see if we should add something in the docs about configureBabelPresetEnv(). I don't know what that is and if Encore supports it or not. Thanks!

Hey, I think this is not documented because it's part of the recipes. So when you install webpack-encore you should endup with.

.configureBabelPresetEnv((config) => {
  config.useBuiltIns = 'usage';
  config.corejs = 3;
})

We can maybe add this code in the snippet of this page: https://symfony.com/doc/current/frontend/encore/babel.html ?

@WebMamba thanks for your comment ... in #19460 we're trying to make the change you proposed.

It would be nice if a link to an explanation of those preset env settings could be added, too.

[WebMamba]

Do you mean a link to this page: https://babeljs.io/docs/babel-preset-env ?

[stollr]

Yes, that's correct

Good idea! I updated the PR to add the link. Thanks.
