A DNS Server and Client Implementation in Pure JavaScript with no dependencies.

const dns = require('../..');
const path = require('path');
const fs = require('fs');

const { Packet } = dns;

// Create a SSL enabled server
const server = dns.createDOHServer({
  port : 8080,
  ssl  : true,
  cert : fs.readFileSync(path.join(__dirname, 'server.crt')),
  key  : fs.readFileSync(path.join(__dirname, 'secret.key')),
});

// Handle the incomming request (same style as both UDP and TCP server)
server.on('request', (request, send, client) => {
  const response = Packet.createResponseFromRequest(request);
  const [ question ] = request.questions;
  const { name } = question;
  response.answers.push({
    name,
    type    : Packet.TYPE.A,
    class   : Packet.CLASS.IN,
    ttl     : 300,
    address : '1.1.1.1',
  });
  send(response);
});

server.listen();
