API

fmtObj(obj, depth = Infinity, colors = defaultColorMap, offset = 2)

Prettifies obj given a colors map with optional depth.

depth (optional)

Objects deeper than depth will get collapsed and hide their sub properties.

colors (optional)

fmt-obj uses chalk behind the scenes. You can tweak the color mapping by the following tokens:

• punctuation - The characters sorrounding your data: : and "
• literal - Either true, false, null or undefined
• property
• string
• number

Here is an example of using a custom color map:

const format = require('fmt-obj')
const chalk = require('chalk')

const customFormat = (...args) => format(...args, {
  punctuation: chalk.cyan,
  property: chalk.yellow,
  literal: chalk.blue,
  number: chalk.green,
  string: chalk.bold
})

console.log(customFormat({ hello: 1.0 }))

Default color map

{
  punctuation: chalk.yellow,
  property: chalk.green,
  literal: chalk.magenta,
  number: chalk.cyan,
  string: chalk.bold
}

offset (optional)

The amount of whitespace after the object gets displayed.
