BunFetchRequestInit.proxy

proxy?: string | { headers: HeadersInit; url: string }

Override http_proxy or HTTPS_PROXY This is a custom property that is not part of the Fetch API specification.

Can be a string URL or an object with url and optional headers.

// String format
const response = await fetch("http://example.com", {
 proxy: "https://username:password@127.0.0.1:8080"
});

// Object format with custom headers sent to the proxy
const response = await fetch("http://example.com", {
 proxy: {
   url: "https://127.0.0.1:8080",
   headers: {
     "Proxy-Authorization": "Bearer token",
     "X-Custom-Proxy-Header": "value"
   }
 }
});

If a Proxy-Authorization header is provided in proxy.headers, it takes precedence over credentials parsed from the proxy URL.
