js/globals/webtransport.ts

WebTransport global constructors.

The WebTransport slice of the globals barrel. It re-exports the public WebTransport surface from fino:net/http/webtransport so that runtime bootstrap can install WebTransport and WebTransportDatagramDuplexStream as constructors on globalThis. That installation is what lets browser-style code reference the bare WebTransport constructor without an explicit import, matching the W3C object model.

This module contains no logic of its own — every behavior (session setup over HTTP/3, datagrams, streams, certificate pinning, statistics) lives in fino:net/http/webtransport. Two of the re-exports are values: the WebTransport session class and the WebTransportDatagramDuplexStream datagram facade, which the globals registry pulls in and bootstrap registers as globals. The rest are type-only re-exports carrying the standard dictionary and statistics shapes (WebTransportOptions, WebTransportCloseInfo, WebTransportHash, the stream and stats types) for TypeScript consumers.

Application code should not import this module by name. Use the installed globals directly, or import from fino:net/http/webtransport when you want an explicit dependency and access to the full type surface. The HTTP/3 driver wiring helpers in that module are @internal and are deliberately not re-exported here.

// Bootstrap installs these as globals; no import is needed at the call site.
const transport = new WebTransport('https://example.test/session');
await transport.ready;

const writer = transport.datagrams.createWritable().getWriter();
await writer.write(new Uint8Array([1, 2, 3]));
writer.releaseLock();

transport.close({ closeCode: 0, reason: 'done' });
