Node Reference for Http2Stream

interface Http2Stream

extends [stream.Duplex]

Usage in Deno

import { type Http2Stream } from "node:http2";

Properties

readonly



aborted: boolean

Set to true if the Http2Stream instance was aborted abnormally. When set, the 'aborted' event will have been emitted.

readonly



bufferSize: number

This property shows the number of characters currently buffered to be written. See net.Socket.bufferSize for details.

readonly



closed: boolean

Set to true if the Http2Stream instance has been closed.

readonly



destroyed: boolean

Set to true if the Http2Stream instance has been destroyed and is no longer usable.

readonly



endAfterHeaders: boolean

Set to true if the END_STREAM flag was set in the request or response HEADERS frame received, indicating that no additional data should be received and the readable side of the Http2Stream will be closed.

optional

readonly



id: number | undefined

The numeric stream identifier of this Http2Stream instance. Set to undefinedif the stream identifier has not yet been assigned.

readonly



pending: boolean

Set to true if the Http2Stream instance has not yet been assigned a numeric stream identifier.

readonly



rstCode: number

Set to the RST_STREAM error code reported when the Http2Stream is destroyed after either receiving an RST_STREAM frame from the connected peer, calling http2stream.close(), or http2stream.destroy(). Will beundefined if the Http2Stream has not been closed.

readonly



sentHeaders: OutgoingHttpHeaders

An object containing the outbound headers sent for this Http2Stream.

readonly

optional



sentInfoHeaders: OutgoingHttpHeaders[] | undefined

An array of objects containing the outbound informational (additional) headers sent for this Http2Stream.

readonly

optional



sentTrailers: OutgoingHttpHeaders | undefined

An object containing the outbound trailers sent for this HttpStream.

readonly



session: Http2Session | undefined

A reference to the Http2Session instance that owns this Http2Stream. The value will be undefined after the Http2Stream instance is destroyed.

readonly



state: StreamState

Provides miscellaneous information about the current state of theHttp2Stream.

A current state of this Http2Stream.

Methods



close(code?: number,
callback?: () => void,
): void

Closes the Http2Stream instance by sending an RST_STREAM frame to the connected HTTP/2 peer.



priority(options: StreamPriorityOptions): void

Updates the priority for this Http2Stream instance.



setTimeout(msecs: number,
callback?: () => void,
): void

const http2 = require('node:http2');
const client = http2.connect('http://example.org:8000');
const { NGHTTP2_CANCEL } = http2.constants;
const req = client.request({ ':path': '/' });

// Cancel the stream if there's no activity after 5 seconds
req.setTimeout(5000, () => req.close(NGHTTP2_CANCEL));



sendTrailers(headers: OutgoingHttpHeaders): void

Sends a trailing HEADERS frame to the connected HTTP/2 peer. This method will cause the Http2Stream to be immediately closed and must only be called after the 'wantTrailers' event has been emitted. When sending a request or sending a response, the options.waitForTrailers option must be set in order to keep the Http2Stream open after the final DATA frame so that trailers can be sent.

const http2 = require('node:http2');
const server = http2.createServer();
server.on('stream', (stream) => {
  stream.respond(undefined, { waitForTrailers: true });
  stream.on('wantTrailers', () => {
    stream.sendTrailers({ xyz: 'abc' });
  });
  stream.end('Hello World');
});

The HTTP/1 specification forbids trailers from containing HTTP/2 pseudo-header fields (e.g. ':method', ':path', etc).
