log.json

Method Signature

log.json(data)

Type: Function

Parameter: Any JavaScript value.

Returns: undefined

Example:

import Perj from 'perj'
const log = new Perj(options)
log.json(process.config)

Description

The log.json function is a convenience method that uses the internal perj stringify function to pretty print an object directly to the console. It is really only useful during development although it is not unsafe in any way.

Examples

This example is the same as above with the output shown:

import Perj from 'perj'
const log = new Perj(options)
log.json(process.config)
