Import and Usage Example

const format = require('fmt-obj')

console.log(format({ message: 'hello world', dev: true, awesomeness: 9.99, body: { these: null, are: 'string', some: 12, props: false } }))

API

format(obj, depth = Infinity)

Prettifies

obj
with optional
depth
.

obj

Any arbitrary javascript object.

depth
(optional)

Colapses all properties deeper than specified by

depth
.

createFormatter({ offset = 2, formatter = identityFormatter })

Create a custom format function if you need more control of how you want to format the tokens.

opts.formatter
(optional)

fmt-obj
uses
chalk
for it's default format function. A formatter is mostly used for colors but can be used to manipulate anything.

Example with rounding numbers

js
const format = createFormatter({ number: Math.round })
format({ num: 12.49 }) // -> num: 12

The following tokens are available:

  • punctuation - The characters sorrounding your data:
    :
    and
    "
  • literal - Either
    true
    ,
    false
    ,
    null
    or
    undefined
  • annotation - Type annotation for errors, functions and circular references like
    [Function {name}]
  • property
  • string
  • number

Example with a custom color map ```js const { createFormatter } = require('fmt-obj')

const format = createFormatter({ offset: 4,

formatter: { punctuation: chalk.cyan, annotation: chalk.red, property: chalk.yellow, literal: chalk.blue, number: chalk.green, string: chalk.bold } }) ```

opts.offset
(optional)

The amount of left whitespace between the property key and all of it's sub-properties.
