Proxy HTTP requests using fetch()

In Bun, fetch supports sending requests through an HTTP or HTTPS proxy. This is useful on corporate networks or when you need to ensure a request is sent through a specific IP address.

await fetch("https://example.com", {
  // The URL of the proxy server
  proxy: "https://username:password@proxy.example.com:8080",
});

---

The proxy option is a URL string that specifies the proxy server. It can include the username and password if the proxy requires authentication. It can be http:// or https://.

---

You can also set the $HTTP_PROXY or $HTTPS_PROXY environment variable to the proxy URL. This is useful when you want to use the same proxy for all requests.
