Doesn't follow `package.json` `type` in `rollup.config.ts` code?

Troubleshooting

I’m building with rollup --config rollup.config.ts --configPlugin typescript2 and when encountering a plugin containing only ESM exports during construction then, Rollup throws a ERR_REQUIRE_ESM exception.

At present, many packages have changed to support only ESM. Can rollup-plugin-typescript2 automatically convert to MJS or CJS based on "type": "module" field?

added by agilgur5 from the SO link:

// plugin
import { Plugin } from 'rollup'
import boxen from 'boxen' // this is a only contain esm package

export const totalSize = (): Plugin => {
    const plugin: Plugin = {
        name: 'rollup-plugin-total-size',
        buildEnd() {
            boxen(` point info `)
        }
    }
    return plugin
}

// rollup.config.ts
import { totalSize } from './plugin'

export default () => {
    input: 'lib/index.ts',
    output: 'dist/index.js',
    plugins: [
      // total bundle size
      totalSize()
    ]
}

npm run build works once you fix the package.json (you have an additional comma there).

So this doesn’t quite show the error either 😕
