digz library

DayZ server query library, with DZSA Mod Download Server fallback request. It is built on top of node-gamedig, but focus on providing a simpler DayZ server output.

digz is available as a node.js module, as well as a command line executable.

Usage from Node.js

npm install digz

const digz = require('digz')

digz.query({
  host: '168.100.162.110',
  port: '2303'
}).then((response) => {
  console.log('Server data:', response)
}).catch((error) => {
  console.log('Server is offline')
})

Query parameters

Parameter	Type	Default
host	string	-	Required. Hostname or IP of the server.
port	number	-	Required. Connection port or query port for the server. Make sure it's the query port and not the game port.
pretty	boolean	false	Hostname or IP of the server.
maxAttempts	number	1	Number of attempts to query server in case of failure.
socketTimeout	number	2000	Milliseconds to wait for a single packet. Beware that increasing this will cause many queries to take longer even if the server is online.

The output of the command will be in JSON format. Additional optional parameters can be passed in as well. Ex: --pretty, --socketTimeout 5000, etc.

node-gamedig

This library is built on top of node-gamedig, a more broad game server library. This wouldn't be possible if it wasn't for all their hard work. I decided to put this togeter, because DayZ has it's own misteries and needs a little more love to have fallback options and a simpler query response.
