Convert cURL to JavaScript fetch (safely)
Turn API docs and DevTools cURL snippets into fetch() code. Know which flags translate cleanly and what to fix afterward.
Why convert?
API documentation often shows cURL. Front-end and Node apps usually want fetch. Converting saves time, but you still need error handling, auth storage, and CORS awareness in the browser.
What usually maps well
HTTP method (-X), headers (-H), and simple bodies (-d) map to fetch options. Complex shell features, certificate flags, and cookie jars may not translate one-to-one.
After you paste
Remove hardcoded secrets from examples, parse JSON responses, and handle non-2xx statuses. Use our converter for the scaffold, then harden the code in your project.
