Network & Clipboard APIs

CodeTweak provides enhanced network capabilities, bypassing standard Cross-Origin Resource Sharing (CORS) restrictions.

---

GM_xmlhttpRequest

A more powerful version of the standard XMLHttpRequest (XHR) or fetch.

GM_xmlhttpRequest(details: object): void

Implementation Details

CodeTweak uses a background request handler to execute all network calls. This means:

1. CORS Bypass: Requests are made from the extension's background script, so they are not blocked by the website's CORS policy.
2. No Cookies or Referrer: By default, the browser's context for the target site is not shared with these requests unless configured.

Options

• method: GET, POST, PUT, DELETE, etc.
• url: The target address.
• headers: A set of HTTP headers to send.
• data: The request body.
• timeout: In milliseconds.
• responseType: text, json, blob, arraybuffer.
• onload: Callback for successful completion.
• onerror: Callback for failed requests.
• onprogress: Callback for status updates.

Async Support

In addition to the standard callback-based version, CodeTweak provides an asynchronous version:

const response = await GM.xmlhttpRequest({ ... });

GM_download
