Hot Console

Hot Console is a console log replacer for node that includes colors and shows more detailed results. Such as data types, string lengths, and displays arrays and objects in a more readable format.

It's fast and very easy to use!

var log = require('hot-console')

log('Hello World!') // Use instead of console.log
log(34, { color: 'red', background: 'black' })

log([1, 2, [[4, 5], 'nr 3']], { color: 'yellow' })

log('The %s is %d\n', 'time', Date.now(), { color: 'green' })

Installation

$ npm install hot-console

Examples

var log = require('hot-console')

log.setColor('yellow')
  .setBackground('red')
  .setStyle('bold')

log('This text has yellow color, red background and is in bold')
log('This too but has blue backgound', { background: 'blue' })
log('This has changed alot', { color: 'green', background: 'yellow', style: 'italic' })

// Clear all styles
log.clear()

// Quick functions for just red and green text
log.error('Red text')
  .success('Green text')

// Different argument examples
var d = new Date()
log('Today is: %d-%d-%d', d.getFullYear(), d.getMonth(), d.getDate())
log('The', 'weekday', 'is', d.getDay(), { color: 'yellow' })
log('The hour is: %d and the minute is:', d.getHours(), d.getMinutes())

Extra! Console loading animation

var timeout = log.startLoading('loading', { color: 'yellow' })

// loading...

setTimeout(function () {
  log.clear(timeout)
    .success('Finished loading!')
}, 2000)

Functions

Log

log(s, ...arguments, style) // The console log function

• s: The string/object to console log (can be any datatype).
• ...arguments: When s is a string any amount of arguments can be added in "printf style", or just added to the end (uses util.format).
• style: Style object with 3 valid properties (color, background, style) which has to be the last argument (available colors are listed below).

SetColor, setBackground, setStyle and clear

log.setColor(s) // Sets color to use
  .setBackground(s) // Sets background color to use
  .setStyle(s) // Sets style to use

  .clear() // Clears all styles

• s: String of which color to use in the console.
• Colors: "red", "black", "green", "yellow", "blue", "magenta", "cyan", "white" or "grey" (grey doesn't work for background color). Null to reset.
• Styles: "italic", "bold", "underline", "reset", "dim", "inverse", "hidden", "strikethrough". Null to reset.
• Colors and styles are based on the Colors package (safe version). So check there for more colors/styles.

Error and success

log.error(s, ...arguments) // Quick way to console log in red color
  .success(s, ...arguments) // Quick way to console log in green color

Same arguments as log(), but no style object

StartLoading

var timeout = log.startLoading(s, style) // Starts a console loading animation
log.clear(timeout) // Stops the loading animation

• s: String to use with the loading symbol.
• timeout: Can be anything really, if clear is called with an argument it stops an ongoing animation instead of clearing styles.

SetLoader

log.setLoader(symbol) // Changes loading symbol

• symbol: String of which console loading symbol to use ("rotater", "numbers" or "dots").

SetLoopDepth

log.setLoopDepth(depth)

• depth: Number for max recursion level depth to use when looping through objects and arrays. Default is 10.

ShowStringDetails

log.showStringDetails(show)

• show: Boolean to show/hide all strings datatype and length info in console. Is false by default.
• String details are always shown inside arrays and in objects though.
