Configurable JSON.stringify() logging to any output stream.

• Configurable stringify (see abc-stringify)
• Configurable output stream
• Configurable levels
• Configurable time, level, and log property names
• Configurable watch file to change log level

Quick Start

1const AbcLog = require('abc-log')
2const log = new AbcLog({ level: 'info' })
3const o = {
4  error: new Error('something bad happened'),
5  name: 'freddy',
6  address: {
7    street: '1234 lane st',
8    city: 'hereshey',
9    st: 'PA',
10    zip: '19293'
11  },
12  nest: {
13    really: {
14      deep: {
15        stuff: ['one', 2, 'three']
16      }
17    }
18  }
19}
20o.circular = o
21// Signature is compatible with JSON.stringify(value, replacer, space)
22log.info(o, 2) // same as log.info(o, null, 2)
