const { DNSoverHTTP, DNSoverTLS } = require('dohdec')
const doh = new DNSoverHTTP()
await doh.lookup('ietf.org', 'AAAA') // JSON result from CloudFlare
await doh.lookup('ietf.org', {

Notes
- All queries will be padded to the next multiple of 128 bytes (see RFC 8467)
- The JSON protocols are not standardized. The best we have is Google's documentation, which Cloudlflare seems to have followed.
