log.stringify

Method Signature

log.stringify(object, replacer, spacer)

Type: Function

Parameter: object Any JavaScript value or object.

Parameter: replacer A replacer function.

Parameter: spacer A number or string used to insert space for formatting.

Returns: JSON String

Example:

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

Description

The log.stringify function is a convenience method that exposes the internal perj stringify function. By default this is based on the notation-copy module wrapped by JSON.stringify.

If you change the stringify function using the stringifyFunction option, then your custom stringify function will be used by the log.stringify call.

Examples

This example shows the use of both the log.stringify function and the log.write function:

import Perj from 'perj'
const log = new Perj()

const thing = log.stringify(process.config)
log.write(thing)
