API

We import as follows:

const doh = require('@sagi.io/dns-over-https')

doh.query(...)

doh.query = ({
  name,
  method = 'POST',
  hostname = 'cloudflare-dns.com',
  path = '/dns-query',
  port = 443,
  userAgent = '@sagi.io/dns-over-https',
  type = 'A',
  klass = 'IN',
  useHttps = true,
})

A name is mandatory. You can set your own method, hostname, path, port, userAgent, type, klass and useHttps.

A Promise that resolves to a DNS response object is returned.

For instance,

const doh = require('@sagi/dns-over-https')
(async () => {
  const dnsResponse  = await doh.query({name: 'sagi.io'})
})()

Results in:
