nessie

A friendly DNS client for Gleam programs targeting Erlang.

gleam add nessie

import nessie
import gleam/io

pub fn main() {
 let ipv4_addrs = nessie.lookup_ipv4("gleam.run", nessie.In, [])
 io.debug(ipv4_addrs)
}

Further documentation can be found at https://hexdocs.pm/nessie.

Supported DNS Records

The following is a list of supported DNS record types. If nessie doesn’t currently support a DNS record type you want, feel free to contribute to this project!

• A
• AAAA
• TXT
• CNAME
• MX
• SOA
• NS
• PTR
• SRV
• CERT
• DCHID
• DNAME
• DNSKEY
• DS

What about JavaScript support?

Due to Erlang and JavaScript’s fundamentally different approaches to asynchronous programming (processes & event loops, respectively), it’s not currently possible in Gleam to write a DNS client supporting both targets.

For more information, see this Discord thread.
