Streamline API Integration in JavaScript and Node.js
Most developer documentation, third-party API references (Stripe, GitHub, Twilio, OpenAI), and Chrome DevTools network tab exports express HTTP interactions as curl command line strings. Manually rewriting these cURL flags into modern JavaScript fetch() or axios calls requires splitting headers, configuring JSON payloads, and formatting asynchronous promise chains.
The cURL to JavaScript Converter parses flags such as -X, -H, -d, -u, and --compressed into elegant, modular JavaScript code tailored for both modern browser applications and backend Node.js microservices.
Supported cURL Flags & Mappings
- -X / --request: Maps HTTP methods (GET, POST, PUT, DELETE, PATCH).
- -H / --header: Formatted into a clean headers object.
- -d / --data / --data-raw: Automatically checks if the payload is valid JSON and assigns it appropriately to the request body.
- -u / --user: Injects the computed
Authorization: Basic base64(user:pass)header.
Frequently Asked Questions
Can I use the generated fetch() code in Node.js?
Yes! Since Node.js version 18, the Fetch API is natively built-in without requiring node-fetch or external packages.
How does Axios handle request data compared to Fetch?
Axios automatically serializes JavaScript objects to JSON and sets the
Content-Type: application/json header automatically, whereas Fetch requires JSON.stringify(body) and explicit header definition. Our converter adapts the syntax accurately for each client.
