quickly retreive environment information

I find myself frequently looking up which version of Node and npm I’m running.

Today, a colleague showed me how to get it and lots of additional useful infromation with a single command:

npx envinfo --binaries --languages --system --utilities

This will print out all of the information in an easy to read and digest format like so:

$ npx envinfo --binaries --languages --system --utilities
npx: installed 1 in 1.792s

  System:
    OS: macOS 10.15.2
    CPU: (8) x64 Intel(R) Core(TM) i5-8259U CPU @ 2.30GHz
    Memory: 34.86 MB / 8.00 GB
    Shell: 5.7.1 - /usr/local/bin/zsh
  Binaries:
    Node: 12.13.0 - ~/.nvm/versions/node/v12.13.0/bin/node
    Yarn: 1.19.1 - /usr/local/bin/yarn
    npm: 6.13.0 - ~/.nvm/versions/node/v12.13.0/bin/npm
  Utilities:
    Make: 3.81 - /usr/bin/make
    GCC: 4.2.1 - /usr/bin/gcc
    Git: 2.24.0 - /usr/local/bin/git
    Clang: 1100.0.33.16 - /usr/bin/clang
    Subversion: 1.10.4 - /usr/bin/svn
  Languages:
    Bash: 3.2.57 - /bin/bash
    Go: 1.13.4 - /usr/local/go/bin/go
    Java: 11.0.2 - /usr/bin/javac
    Perl: 5.18.4 - /usr/bin/perl
    PHP: 7.3.9 - /usr/bin/php
    Python: 2.7.17 - /usr/local/bin/python
    Python3: 3.7.5 - /usr/local/bin/python3
    Ruby: 2.6.3 - /usr/bin/ruby

It is a nice alternative to typing out each command separately like so:

$ zsh --version
zsh --version
zsh 5.7.1 (x86_64-apple-darwin18.2.0)
$ node --version
node --version
v13.1.0
$ npm --version
npm --version
6.12.1
