  +Since Node.js does not yet support the [`fetch API`](https://developer.mozilla.org/en-US/docs/Web/API/Fetch_API/Using_Fetch), you'll need to provide your own `fetch` function in the options object. Note that `fetch` must return a [Web Stream](https://nodejs.org/api/webstreams.html), so [node-fetch](https://github.com/node-fetch/node-fetch) won't work, but [node/undici's](https://undici.nodejs.org/) implementation will.
