jonschlinkert / patchy-patch-patch.md
Created Jun 19, 2019
The very brief guide to getting rid of NPM's annoying "vulnerability" messages for packages that have been patched.
View patchy-patch-patch.md

  1. You see a vulnerability warning for a package, and
  2. The package has already been fixed, and a patch version has been released.

TLDR;

  1. Delete all lock files
