Replacements for rollup-plugin-babel

@rollup/plugin-babel

rollup-plugin-babel is deprecated. Its replacement, @rollup/plugin-babel, is maintained in Rollup's official plugins repository.

The main migration change is replacing the default babel import with a named import. The current plugin also requires an explicit babelHelpers option.

Example:

import babel from 'rollup-plugin-babel'
import { babel } from '@rollup/plugin-babel'

export default {
  plugins: [babel()] 
  plugins: [babel({ babelHelpers: 'bundled' })] 
}
