Events

This plugin listens on a few events providing the resolver to other plugins that wish to make use of it.

dns.resolve

The dns.resolve event accepts a callback that will be called with a Promise that will resolve once the given hostname has been resolved. (If promises are new to you, be sure to read this.)

$this->emitter->emit('dns.resolve', [function($promise) use ($callback, $that) {
    $promise->then(function($ip) {
        echo 'IP for github.com: ' . $ip . PHP_EOL;
    });
}]);

dns.resolver

The dns.resolver event accepts a callback that will be called once a Resolver instance has been created.

$this->emitter->emit('dns.resolver', [function($resolver) use ($callback, $that) {
    $resolver->resolve('github.com')->then(function($ip) {
        echo 'IP for github.com: ' . $ip . PHP_EOL;
    });
}]);
