@sec-ant/gm-fetch

A fetch API for GM_xmlhttpRequest / GM.xmlHttpRequest.

Features

Use Typescript.
Provides es module, iife script and lib mode userscript as well.

If you use vite-plugin-monkey:

npm i @sec-ant/gm-fetch

or just plain userscript (change latest to the version number as needed):

Usage

Grant necessary GM_APIs:

vite-plugin-monkey:

{
  plugins: [
    monkey({
      userscript: {
        // or GM.xmlHttpRequest
        grant: "GM_xmlhttpRequest",
        // whatever websites you're to make requests to
        connect: ["github.com"],
      },
    }),
  ];
}

plain userscript:

// @grant     GM_xmlhttpRequest
// @connect   github.com

Use it just like fetch:

/* globals gmFetch */
(function () {
