Does the fetch output work in Node.js?

Yes — `fetch` is built into Node.js 18+ with no install required. For older Node versions, use the `node-fetch` option from the language picker, or pick `Node (Axios)` for an axios-based snippet.

How do I add error handling?

Wrap the call in a `try/catch` and check `response.ok` (or `response.status`) before reading the body. `fetch` doesn't throw on 4xx/5xx by default, only on network errors.

Can I get the axios version instead?

Yes. Pick `Node (Axios)` or `JavaScript (jQuery)` from the language picker for those alternatives.

Will it work in service workers and edge runtimes?

Yes — the generated `fetch` code runs in Cloudflare Workers, Deno Deploy, Vercel Edge Functions, Bun, browsers, and any modern JS runtime that supports the standard `fetch` API.

How to copy a curl command from DevTools

Most browsers can export any network request as a ready-to-paste curl command.

Chrome / Edge

Open DevTools (F12 or Cmd/Ctrl + Shift + I)
Go to the Network tab and reload the page
Right-click a request → Copy → Copy as cURL

Firefox

Open the Network Monitor in DevTools
Right-click a request → Copy Value → Copy as cURL
Paste it in the input above

Safari

Enable the Develop menu in Settings → Advanced
Open Web Inspector → Network tab
Right-click a request → Copy as cURL

Your data stays in your browser

We never transmit, store, or log the curl commands you paste. All parsing and conversion happens client-side using JavaScript.

Watch for secrets

Curl commands copied from DevTools often contain cookies, bearer tokens, or API keys. Never share converted code without scrubbing those values first.

About converting curl to JavaScript (fetch)

Convert curl to JavaScript using the native `fetch` API — the standard way to make HTTP requests in modern browsers and Node.js 18+. The generated code is dependency-free, works in any modern browser, and uses async/await for clean, readable request handling. Headers, JSON bodies, query strings, basic and bearer authentication, and most curl flags are translated faithfully. This is the right choice for browser apps, Cloudflare Workers, Deno, Bun, and any environment where you don't want to add a dependency.
