Frequently Asked Questions

How does this tool convert cURL to Node.js code?
It tokenizes your cURL command, parses HTTP method, headers, auth, cookies, and data, and generates production-ready Node.js scripts using Axios, Fetch, or HTTPS.
Does it support the native global fetch in Node.js 18+?
Yes! Node 18+ Fetch mode generates clean async/await fetch() code without requiring any external npm package installations.
Can I generate CommonJS require syntax instead of ESM import?
Yes. Toggle between ESM (import) and CommonJS (require) with a single click in the options bar.
How does it handle Basic Auth and Bearer tokens?
Basic Auth (-u user:pass) is mapped to Axios auth config or Base64 Authorization headers, while Bearer tokens are preserved in standard HTTP headers.

Methodology

This tool runs entirely in your browser. The example above shows a representative input and the result it produces.
