Usage

const dnscrypt = require('dnscrypt');

dnscrypt.resolve('example.com', (err, addresses) => {
  if (err) {
    console.error(err);
  } else {
    console.log(addresses);
  }
});

// Supports both callback and promise-based styles.
await dnscrypt.resolve4('example.com');

const resolver = dnscrypt.createResolver({ timeout: 1e3 });

How to

• Use global api dnscrypt.resolve for single looking up.
• Use resolver api dnscrypt.createResolver() for multiple lookups (to avoid repeated certificate requests).

• dnscrypt.resolve6(hostname[, options], callback): void
• dnscrypt.resolve6(hostname[, options]): Promise

See dns.resolve6.

• dnscrypt.resolveCname(hostname, callback): void
• dnscrypt.resolveCname(hostname): Promise

See dns.resolveCname.

• dnscrypt.resolveMx(hostname, callback): void
• dnscrypt.resolveMx(hostname): Promise

See dns.resolveMx.

• dnscrypt.resolveNs(hostname, callback): void

• dnscrypt.createResolver([options]): Resolver

Create a new independent resolver for DNS requests.

• options.timeout: number - The number of milliseconds before a request times out, 2s default.
• options.unref: bool - Call .unref() on internal dgram socket.
• options.sdns: string - Use secure DNS resolver instead of default one.
