Quick Start

const AbcLog = require('abc-log')
const log = new AbcLog({ level: 'info' })
const o = {
  error: new Error('something bad happened'),
  name: 'freddy',
  address: {
    street: '1234 lane st',
    city: 'hereshey',
    st: 'PA',
    zip: '19293'
  },
  nest: {
    really: {
      deep: {
        stuff: ['one', 2, 'three']
      }
    }
  }
}
o.circular = o
// Signature is compatible with JSON.stringify(value, replacer, space)
log.info(o, 2) // same as log.info(o, null, 2)
