environmentalize does not work with object whitelisting

[jhiode]

We noticed in Hops that we can't use environment variables when whitelisting a full object.

Example:

module.exports = {
  foo: {
    bar: '[FOOBAR]',
  },
  browserWhitelist: {
    foo: true, // does not add `FOOBAR` to the list of environment variables and `foo.bar` will be an empty string.
  },
};

It works though if we use the full path for the entry:

module.exports = {
  foo: {
    bar: '[FOOBAR]',
  },
  browserWhitelist: {
    'foo.bar': true, // this works as expected
  },
};

Root cause is that we only check for the full path (line 95):

untool/packages/core/lib/utils.js

Lines 92 to 100 in ef7abcc

	if (regExp.test(item)) {
	return item.replace(regExp, (_, key, fallback) => {
	const replaced = env[key] || fallback || '';
	if (whitelist[path.join('.')]) {
	_env[key] = replaced;
	}
	return replaceRecursive(replaced);
	});
	}
