CommonJS Require

[arb]

I am trying to use the plugin to require in package.json to include on the version information. When I look at the resultant bundling, the entire JSON object has been pulled in, recreated, and frozen with Object.freeze. I've tried moving this plugin around to different spots in the plugins array with no success.

My end goal is I just want the version property.

My plugins stack looks like this

const plugins = [
  resolve({
    browser: true,
    preferBuiltins: false,
  }), json(), commonJs(), babel({
    exclude: 'node_modules/**',
    presets: ['es2015-rollup']
  })];

This is an old issue and probably no longer relevant but just some feedback:
Tree-shaking in JSON files will only work if the file is imported using named ES modules imports. require can only be translated into a default import which will always import the whole JSON file.

Feel free to reopen this if you need more clarification.
