In Chrome or Edge: open DevTools (F12) → Network tab → perform the request → right‑click the request → Copy → Copy as cURL. In Firefox: same steps, then Copy as cURL. Postman and other API tools also offer “Copy as cURL”.

It supports the most common options: -X/--request, -H/--header, -d/--data, -u/--user (Basic auth), -G/--get, and --url. Options like -k (insecure) or --compressed are not reflected in the fetch output.

Yes. In Node.js 18+ the native fetch is available. For older Node, use a polyfill (e.g. node-fetch) or run the code in the browser.

Ensure the command starts with curl and includes a valid URL (e.g. https://...). Multi-line cURL is supported. If it still fails, simplify the command to the minimal form (e.g. curl 'https://api.example.com') and add options back one by one.
