Babel: [BUG] Babel 7 with es2015 preset incorrectly destructures from imported module.

Created on 3 Oct 2017 · 3Comments · Source: babel/babel

Input Code

Cloneable/runnable example can be found here.

Given a module that exports an object:

export const NestedObjects = {
  Foo: "whatevs",
  Bar: "whatevs",
}

And a module that imports the object and then destructures it into multiple objects:

import { NestedObjects } from "./some-module"
const { Foo, Bar } = NestedObjects

Babel Configuration

{
  "presets": ["es2015"]
}

Expected Behavior

I would expect both Foo and Bar to be taken from _someModule.NestedObjects.

Current Behavior

Only the first destructured object is resolved correctly _someModule.NestedObjects.Foo, the following object loses the module reference NestedObjects.Bar.

Possible Solution

I have not had the time yet to drill it down to the specific plugin in the es2015 preset that causes this, so that should probably be the first avenue to explore. I will update this ticket if I do find time to debug more before someone else has had the opportunity to do so.

Context

Our React Native project tries to use this library, which currently fails the build.
