A time stamped log function with an allow list, block list and solo list that filters log messages based on an optional tag param. Future: optional color, optional spacing, solo list

log.js

export var blockList = []
export var allowList = []
// export var soloList = ['foo']


// TODO
// - prepend the name of the arguments that it is printing out?
// - optional color
// - optional spacing
// - solo list
export default function log(msg, tag=null){
  let d = new Date()
  let mo = (d.getMonth() < 10 ? '0' : '') + d.getMonth() + 1
  let da = (d.getDate() < 10 ? '0' : '') + d.getDate()
  let ho = (d.getHours() < 10 ? '0' : '') + d.getHours()
  let mi = (d.getMinutes() < 10 ? '0' : '') + d.getMinutes()
  let se = (d.getMinutes() < 10 ? '0' : '') + d.getMinutes()
  let ms = (((d.getMilliseconds() < 100) ? '0' : '') + ((d.getMilliseconds() < 10) ? '0' : '') + d.getMilliseconds())
  let LOG_PREFIX = '\x1b[32m' + d.getFullYear() + '.' + mo + '.' + da + '-' + ho + ':' + mi + ':' + se + ':' + ms + '\x1b[0m\n ';

  // 1. Convert args to a normal array
  // var args = Array.prototype.slice.call(arguments);

  // 2. Prepend log prefix log string
  // args.unshift(LOG_PREFIX + " ");

  if (allowList.includes(tag) || !(blockList.includes('*') || blockList.includes(tag))) {
    let message = LOG_PREFIX + msg + '\x1b[0m';
    console.log(message);
