Refactoring JavaScript Barrel File

test.js

const {bar, foo} = require('./group1');
const {oof, rab} = require('./group2');

foo();
bar();
oof();
rab();

group1/index.js

const bar = require('./bar')
const foo = require('./foo')

module.exports = {
    bar,
    foo,
}

group1/bar.js

const bar = () => {
    console.log('bar');
}
module.exports = bar;

Given this type of project how would refactoring foo into group2 work using IntelliJ? Is there a refactoring tool that could do this for me? If I want to be able to refactor should I avoid using barrel files?
