knockknocknode v1.0.0

KnockKnockNode

Checks which node version is running and compares it with the node version documented in the package.json. If the versions matches, then the app will continue to install or run. If not, it will try to switch or install the correct version using n.

This package it dependent on n to be installed.

Dependencies

n node package manager is required for this to work link https://github.com/tj/n

Example

package.json

  "engines": {
    "node": ">=16.17.1"
  },
  "scripts": {
    "preinstall": "node knockKnockNode",
    "prestart": "node knockKnockNode",
    "start": "node index"
  },

Required steps

The n command downloads and installs to /usr/local by default, but you may override this location by defining N_PREFIX. n caches Node.js versions in subdirectory n/versions. The active Node.js version is installed in subdirectories bin, include, lib, and share.

To avoid requiring sudo for n and npm global installs, it is suggested you either install to your home directory using N_PREFIX, or take ownership of the system directories:

sudo chown -R $(whoami) /usr/local/n
sudo chown -R $(whoami) /usr/local/bin /usr/local/lib /usr/local/include /usr/local/share
