/**
 * @packageDocumentation
 *
 * A [libp2p transport](https://libp2p.io/docs/transports-overview/) based on [WebTransport](https://www.w3.org/TR/webtransport/).
 *
 * > ⚠️ **Note**
 * >
 * > This WebTransport implementation currently only allows dialing to other nodes. It does not yet allow listening for incoming dials. This feature requires QUIC support to land in Node JS first.
 * >
 * > QUIC support in Node JS is actively being worked on. You can keep an eye on the progress by watching the [related issues on the Node JS issue tracker](https://github.com/nodejs/node/labels/quic)
 *
 * @example
 *
 * ```TypeScript
 * import { createLibp2p } from 'libp2p'
 * import { webTransport } from '@libp2p/webtransport'
 * import { noise } from '@libp2p/noise'
 *
 * const node = await createLibp2p({
 *   transports: [
 *     webTransport()
 *   ],
 *   connectionEncrypters: [
 *     noise()
 *   ]
 * })
 * ```
