/**
 * Creates a Hono middleware that proxies requests using http-proxy-middleware.
 *
 * @remarks
 * This middleware requires Hono to be running on Node.js via `@hono/node-server`.
 * It uses `c.env.incoming` and `c.env.outgoing` which are only available with `HttpBindings`.
 *
 * @experimental This API is experimental and may change without a major version bump.
 *
 * @example
 * ```ts
 * import { serve } from '@hono/node-server';
 * import { Hono } from 'hono';
 * import { createHonoProxyMiddleware } from 'http-proxy-middleware/hono';
 *
 * const app = new Hono();
 * app.use('/api', createHonoProxyMiddleware({ target: 'http://example.com', changeOrigin: true }));
 * serve(app);
 * ```
 *
 * @since 4.0.0
