Node: Feature request - add terminal colors to core

Created on 13 Jul 2018 · 3Comments · Source: nodejs/node

I have some scripts for which installing dependencies / node_modules would be overkill, but I still could use some colors for the terminal. Right now, I think in userland it's standard to install colors/chalk in node_modules but I am wondering if there is a way to do so with just Node.js core?

Seems like it would be handy for scripts and wouldn't add too much to core? dunno

i don't think core needs to expose this, it's quite simple to do even without a library:

const colors = {
  'bold': [1, 22],
  'italic': [3, 23],
  'underline': [4, 24],
  'inverse': [7, 27],
  'white': [37, 39],
  'grey': [90, 39],
  'black': [30, 39],
  'blue': [34, 39],
  'cyan': [36, 39],
  'green': [32, 39],
  'magenta': [35, 39],
  'red': [31, 39],
  'yellow': [33, 39]
};

function stylize(color, str) {
  const [start, end] = colors[color];
  return `\u001b[${start}m${str}\u001b[${end}m`;
}

I agree, this isn't something that needs to explicitly live in or be exposed in core.

Closing this, as @devsnek pointed out a solution that doesn't involve adding things to core any more than what's absolutely necessary. Also, popular solutions exist in the userland. Feel free to reopen this if you feel otherwise.
