Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Zone File JS

CircleCI npm npm npm Slack

An RFC1035-compliant DNS zone file parser and generator for Node.js and the browser. Based on the dns-zonefile library by Elgs Qian Chen.

Installation

$ npm install zone-file

Usage

Making Zone Files

import { makeZoneFile } from 'zone-file'
let zoneFileText = makeZoneFile(zoneFileJson)

Parsing Zone Files

import { parseZoneFile } from 'zone-file'
let zoneFileJson = parseZoneFile(zoneFileText)

Zone File Objects

import { ZoneFile } from 'zone-file'

let zoneFileData = {
  "$origin": "MYDOMAIN.COM.",
  "$ttl": 3600,
  "a": [
    { "name": "@", "ip": "127.0.0.1" },
    { "name": "www", "ip": "127.0.0.1" }
  ]
}

let zoneFile = new ZoneFile(zoneFileData)
let zoneFileString = zoneFile.toString()
let zoneFileJson = zoneFile.toJSON()

Background Info

This library accepts both zone data expressed as a JSON object or as a plain text zone file. It supports SOA, NS, A, AAAA, CNAME, MX, PTR, SRV, TXT and URI record types as well as the $ORIGIN keyword (for zone-wide use only). Each record type (and the $ORIGIN keyword) is optional, although bind expects to find at least an SOA record in a valid zone file.

Forward DNS Zone Files

The following JSON produces a zone file for a forward DNS zone:

{
    "$origin": "MYDOMAIN.COM.",
    "$ttl": 3600,
    "soa": {
        "mname": "NS1.NAMESERVER.NET.",
        "rname": "HOSTMASTER.MYDOMAIN.COM.",
        "serial": "{time}",
        "refresh": 3600,
        "retry": 600,
        "expire": 604800,
        "minimum": 86400
    },
    "ns": [
        { "host": "NS1.NAMESERVER.NET." },
        { "host": "NS2.NAMESERVER.NET." }
    ],
    "a": [
        { "name": "@", "ip": "127.0.0.1" },
        { "name": "www", "ip": "127.0.0.1" },
        { "name": "mail", "ip": "127.0.0.1" }
    ],
    "aaaa": [
        { "ip": "::1" },
        { "name": "mail", "ip": "2001:db8::1" }
    ],
    "cname":[
        { "name": "mail1", "alias": "mail" },
        { "name": "mail2", "alias": "mail" }
    ],
    "mx":[
        { "preference": 0, "host": "mail1" },
        { "preference": 10, "host": "mail2" }
    ],
    "txt":[
        { "name": "txt1", "txt": "hello" },
        { "name": "txt2", "txt": "world" }
    ],
    "srv":[
        { "name": "_xmpp-client._tcp", "target": "jabber", "priority": 10, "weight": 0, "port": 5222 },
        { "name": "_xmpp-server._tcp", "target": "jabber", "priority": 10, "weight": 0, "port": 5269 }
    ]
}

dns-zonefile will produce the following zone file from the above information, while the following zone file can as well be parsed to produce the zone file like above:

; Zone: MYDOMAIN.COM.
; Exported  (yyyy-mm-ddThh:mm:ss.sssZ): 2014-09-22T21:10:36.697Z

$ORIGIN MYDOMAIN.COM.
$TTL 3600

; SOA Record
@	 		IN	SOA	NS1.NAMESERVER.NET.	HOSTMASTER.MYDOMAIN.COM.	(
			1411420237	 ;serial
			3600	 ;refresh
			600	 ;retry
			604800	 ;expire
			86400	 ;minimum ttl
)

; NS Records
@	IN	NS	NS1.NAMESERVER.NET.
@	IN	NS	NS2.NAMESERVER.NET.

; A Records

mail	IN	A	127.0.0.1

; AAAA Records
@	IN	AAAA	::1
mail	IN	AAAA	2001:db8::1

; CNAME Records
mail1	IN	CNAME	mail
mail2	IN	CNAME	mail

; TXT Records
txt1	IN	TXT	"hello"
txt2	IN	TXT	"world"

; SRV Records
_xmpp-client._tcp	IN	SRV	10	0	5222	jabber
_xmpp-server._tcp	IN	SRV	10	0	5269	jabber

Reverse DNS Zone Files

This JSON will produce a zone file for a reverse DNS zone (the $ORIGIN keyword is recommended for reverse DNS zones):

{
	"$origin": "0.168.192.IN-ADDR.ARPA.",
	"$ttl": 3600,
	"soa": {
		"mname": "NS1.NAMESERVER.NET.",
		"rname": "HOSTMASTER.MYDOMAIN.COM.",
		"serial": "{time}",
		"refresh": 3600,
		"retry": 600,
		"expire": 604800,
		"minimum": 86400
	},
  "ns": [
      { "host": "NS1.NAMESERVER.NET." },
      { "host": "NS2.NAMESERVER.NET." }
  ],
  "ptr":[
      { "name": 1, "host": "HOST1.MYDOMAIN.COM." },
      { "name": 2, "host": "HOST2.MYDOMAIN.COM." }
  ]
}

dns-zonefile will produce the following zone file from the above information, while the following zone file can as well be parsed to produce the zone file like above:

; Zone: 0.168.192.IN-ADDR.ARPA.
; Exported  (yyyy-mm-ddThh:mm:ss.sssZ): 2014-09-22T21:10:36.698Z

$ORIGIN 0.168.192.IN-ADDR.ARPA.
$TTL 3600
