abc-stringify

Safe, simple, configurable JSON.stringify()

Handles recursive objects.

Handles Error objects and lets you specify your own error replacer function.

Allows array replacers to either include or exclude keys.

Allows you to specify a list of values to replace (think passwords and keys in your config).

Allows omitting the replacer parameter and just pass the space parameter.

Quick Start

let ss = new AbcStringify()
const o = {
  name: 'abc stringify',
  error: new Error('something bad happened'),
  address: {
    street: '123 string st',
    city: 'hershey',
    st: 'pa',
    zip: '17033'
  },
  nest: {
    really: {
      deep: {
        stuff: ['one', 2, {
          another: 'thing here'
        }]
      }
    }
  }
}
o.circular = o
console.log(ss.stringify(o, 2))
