zonefile-parser

A DNS zonefile parser module with no runtime dependencies, generated from the PEG.js grammar https://github.com/tableflip/zonefile-pegjs

Handles multi-line SOA and TXT records, as well as SRV, MX, CNAME, NS, AAAA, A and friends.

Install

npm install zonefile-parser

Usage

The parser comes in two flavors:

fast.js, the default module exported:

var parser = require('zonefile-parser')
parser.parse('tableflip.io. 21599 IN A 178.62.82.182')
// { origin: null, ttl: null, records:[ { name:'tableflip.io.', ttl: '21599', type:'A', data: '178.62.82.182' } ] }

and small.js in case you're browserifying and want to shave a few bytes:

var parser = require('zonefile-parser/small')
parser.parse('tableflip.io. 21599 IN A 178.62.82.182')
// { origin: null, ttl: null, records:[ { name:'tableflip.io.', ttl: '21599', type:'A', data: '178.62.82.182' } ] }

Command line tool

Install it globally

npm install -g zonefile-parser

and use it from your shell as zonefile to convert a zonefile to JSON on stdout:

$ zonefile ../zonefile-pegjs/test/example.zone
{
  "origin": "example.org.",
  "ttl": "2d",
  "records": [
    {
      "name": "@",
      "ttl": null,
      "type": "SOA",
      "data": {
        "nameServer": "ns1.example.org.",
        "email": "hostmaster.example.org.",
        "serial": "2003080800",
        "refresh": "12h",
        "retry": "15m",
        "expiry": "3w",
        "minimum": "3h"
      }
    }
  ]
}
