Problem

When using a node installer like nvm, every time you upgrade node you need to re-install your global modules.

nvm includes nvm reinstall-packages <version>, but this is a manual process, and if you're jumping between versions frequently, you probably don't even remember which node version has the global modules you recently discovered and installed.

Solution

Module

nvm-global-installs will loop through all of the installed versions of node and return an array of installed packages and versions for each version.

{
  "2.3.0": {
    "npm": "2.11.1",
    "trash": "1.4.1"
  },
  "2.1.0": {
    "nodemon": "1.3.7",
    "npm": "2.10.1",
    "npm-check": "3.2.10"
  }
}

CLI

As a command line it might look like using npm ls --depth=0 for a bunch of node versions like such:

• Order is from newest node version to oldest.
• The active version of node is highlighted.
• Packages not installed are in the active version of node are highlighted.
• If the package is installed but the version is different only the version is highlighted.
