npm and symlinks

`npm link`

→ Runs npm install and then symlinks the current module into your globals

`npm link /path/to/thing`

→ If thing is already in globals, unlink it.

These is a basic console capability test. Clone this repo (https://gist.github.com/58553b13c477de79069e.git) and use node cat console-test.txt to dump the test to your screen. (On Mac & Linux you can just use cat.) There's also a hide-cursor.txt and show-cursor.txt that should do what they say.

All of this is about me trying to figure out what actually is shared cross platform and what isn't.

What I've learned so far is:

made a folder called install-package-lock-only containing only a package.json with these contents:

{
  "name": "install-package-lock-only",
  "version": "1.0.0",
  "dependencies": {
    "mkdirp": "^0.3.4"
 }

Times are off of my Linux laptop.

You can run with: ```console $ npx https://gist.github.com/acfba145e421d51c4de2cdb7faa3f309.git


With default config, using node_modules, which has 1295 files (6.6M):

```console
