resolve-alpn

API

resolveALPN(options)

Returns an object with an alpnProtocol property. The socket property may be also present.

const result = await resolveALPN({
	host: 'nghttp2.org',
	port: 443,
	ALPNProtocols: ['h2', 'http/1.1'],
	servername: 'nghttp2.org'
});

console.log(result); // {alpnProtocol: 'h2'}

Note: While the servername option is not required in this case, many other servers do. It's best practice to set it anyway.

Note: If the socket times out, the promise will resolve and result.timeout will be set to true.

options

Same as TLS options.

options.resolveSocket

By default, the socket gets destroyed and the promise resolves.
If you set this to true, it will return the socket in a socket property.

const result = await resolveALPN({
	host: 'nghttp2.org',
	port: 443,
	ALPNProtocols: ['h2', 'http/1.1'],
	servername: 'nghttp2.org',
	resolveSocket: true
});

console.log(result); // {alpnProtocol: 'h2', socket: tls.TLSSocket}

// Remember to destroy the socket if you don't use it!
result.socket.destroy();
