A `Http2ServerRequest` object is created by Server or SecureServer and passed as the first argument to the `'request'` event. It may be used to access a request status, headers, and data.

This object is created internally by an HTTP server, not by the user. It is passed as the second parameter to the `'request'` event.

Returns a `ClientHttp2Session` instance. ```js import http2 from 'node:http2'; const client = http2.connect('https://localhost:1234'); // Use the client client.close(); ```

Returns a `tls.Server` instance that creates and manages `Http2Session` instances. ```js import http2 from 'node:http2'; import fs from 'node:fs'; const options = { key: fs.readFileSync('server-key.pem'), cert: fs.readFileSync('server-cert.pem'), }; // Create a secure HTTP/2 server const server = http2.createSecureServer(options); server.on('stream', (stream, headers) => { stream.respond({ 'content-type': 'text/html; charset=utf-8', ':status': 200, }); stream.end('

Hello World

'); }); server.listen(8443); ```

Returns a `net.Server` instance that creates and manages `Http2Session` instances. Since there are no browsers known that support [unencrypted HTTP/2](https://http2.github.io/faq/#does-http2-require-encryption), the use of [createSecureServer](.././node__http2.d.ts/~/createSecureServer) is necessary when communicating with browser clients. ```js import http2 from 'node:http2'; // Create an unencrypted HTTP/2 server. // Since there are no browsers known that support // unencrypted HTTP/2, the use of `http2.createSecureServer()` // is necessary when communicating with browser clients. const server = http2.createServer(); server.on('stream', (stream, headers) => { stream.respond({ 'content-type': 'text/html; charset=utf-8', ':status': 200, }); stream.end('

Hello World

'); }); server.listen(8000); ```

> [!WARNING] Deno compatibility > This function is a non-functional stub. Returns an object containing the default settings for an `Http2Session` instance. This method returns a new object instance every time it is called so instances returned may be safely modified for use.

> [!WARNING] Deno compatibility > This function is a non-functional stub. Returns a `Buffer` instance containing serialized representation of the given HTTP/2 settings as specified in the [HTTP/2](https://tools.ietf.org/html/rfc7540) specification. This is intended for use with the `HTTP2-Settings` header field. ```js import http2 from 'node:http2'; const packed = http2.getPackedSettings({ enablePush: false }); console.log(packed.toString('base64')); // Prints: AAIAAAAA ```

> [!WARNING] Deno compatibility > This function is a non-functional stub. Returns a `HTTP/2 Settings Object` containing the deserialized settings from the given `Buffer` as generated by `http2.getPackedSettings()`.

Create an HTTP/2 server session from an existing socket.

This symbol can be set as a property on the HTTP/2 headers object with an array value in order to provide a list of headers considered sensitive.
