🌀 cURL → fetch() Converter
Browser DevTools "Copy as cURL" is great for sharing requests, but to actually run them in JS you need fetch(). Paste any curl command — we generate the matching fetch() call, preserving method, headers, body, and basic auth.
Examples
curl -H "Authorization: Bearer x" https://api.example.com/datafetch("https://api.example.com/data", { headers: { Authorization: "Bearer x" } })curl -X POST -H "Content-Type: application/json" -d '{"a":1}' https://api.example.comfetch("...", { method: "POST", headers: ..., body: '{"a":1}' })Frequently asked questions
Does it handle multipart/form-data?
Single-file uploads (-F field=@file) need to become FormData in JS. We hint at it but you may need to adjust manually.
What about curl --cookie?
Converted to a Cookie header. Note: in browsers, fetch by default uses credentials: "same-origin" — set credentials: "include" for cross-origin cookies.
Will the converted fetch work in Node.js?
Modern Node (18+) has fetch built in. Older versions need node-fetch or undici.
