Turn a curl command into fetch() code

The job

API documentation almost always shows curl. Rebuilding the same request in fetch() by hand means transcribing the URL, every header, the method, and the body — and it is exactly where typos sneak in. The curl→fetch converter parses the command and emits fetch code you can paste straight into a script or the console.

Converting a command

Paste the curl command — it can span multiple lines with backslashes. The output is a fetch() call with a tidy options object: method, headers, body, and credentials where they apply.

• Covered flags: -X/--request, -H/--header, -d/--data and friends, -u/--user, -A/--user-agent, -e/--referer, -b/--cookie, -F/--form, -L/--location, -k/--insecure, --url.
• Flags it doesn't know are skipped — and listed at the top of the output, so you can see what was dropped rather than guessing.
• `@file` references can't be read from a pasted command; the code shows where to attach the file yourself.

Worked example

`curl -X POST https://api.example.com/users -H 'Authorization: Bearer TOKEN' -H 'Content-Type: application/json' -d '{"name":"Ana"}'` becomes `fetch("https://api.example.com/users", { method: "POST", headers: { "Authorization": "Bearer TOKEN", "Content-Type": "application/json" }, body: '{"name":"Ana"}' })` — drop a `.then(r => r.json())` on the end and it runs.

Where it stops

It generates a browser-compatible call: -k/--insecure is noted but browsers can't disable TLS verification, and -L matters only inside fetch's own redirect handling. Output is ES2020-style fetch — for axios or Node's https, treat it as a reference request rather than final code. Commands up to 100,000 characters.
