For HTTP/2 Client Http2Session instances only, the http2session.request() creates and returns an Http2Stream instance that can be used to send an HTTP/2 request to the connected server.

When a ClientHttp2Session is first created, the socket may not yet be connected. if clienthttp2session.request() is called during this time, the actual request will be deferred until the socket is ready to go. If the session is closed before the actual request be executed, an ERR_HTTP2_GOAWAY_SESSION is thrown.

This method is only available if http2session.type is equal to http2.constants.NGHTTP2_SESSION_CLIENT.

import http2 from 'node:http2';
const clientSession = http2.connect('https://localhost:1234');
const {
  HTTP2_HEADER_PATH,
  HTTP2_HEADER_STATUS,
} = http2.constants;

const req = clientSession.request({ [HTTP2_HEADER_PATH]: '/' });
req.on('response', (headers) => {
  console.log(headers[HTTP2_HEADER_STATUS]);
  req.on('data', (chunk) => { // ..  });
  req.on('end', () => { // ..  });
});

When the options.waitForTrailers option is set, the 'wantTrailers' event is emitted immediately after queuing the last chunk of payload data to be sent. The http2stream.sendTrailers() method can then be called to send trailing headers to the peer.

When options.waitForTrailers is set, the Http2Stream will not automatically close when the final DATA frame is transmitted. User code must call eitherhttp2stream.sendTrailers() or http2stream.close() to close theHttp2Stream.

When options.signal is set with an AbortSignal and then abort on the corresponding AbortController is called, the request will emit an 'error'event with an AbortError error.

The :method and :path pseudo-headers are not specified within headers, they respectively default to:

• :method = 'GET'
• :path = /
