Unused url dependency

[screendriver]

index.js

import url from 'url';

export async function foo() {
  // ...
  const bar = url.resolve('...', '...');
  // ...
}

package.json

"dependencies": {
  "url": "0.11.0"
}

depcheck v0.6.6

Unused dependencies
* url

I am using Node.js v7.2.0

This is strange, what is the output of depcheck --json?

I'm seeing this as well in a react-native project.

Depcheck error if url is in package.json dependencies:

19:57 $ depcheck . --ignores=buildStyleInterpolator,eslint-* --ignore-dirs=ios
Unused dependencies
* url

React native fatal error after npm rm -S url:

Thank you for the report!

Quoting from my comment here:

I've done a bit of investigation, and discovered that this false positive happens because depcheck filters out any node.js built-in modules from the list of "used modules" (code to do so is here).

I'm going to close this issue as a duplicate of #251, since I've added some brainstorming about possible solutions there
