Frequently Asked Questions
What cURL command options are translated into JavaScript fetch()?
The converter translates HTTP request methods (-X POST, --request PUT), target URLs, request headers (-H, --header), request data payloads (-d, --data, --data-raw), basic authentication (-u user:pass), and query strings into idiomatic JavaScript fetch() options.
How are JSON request bodies formatted in the generated fetch code?
If the cURL command includes a valid JSON payload in its -d or --data flag, the converter formats it using JSON.stringify() with proper syntax formatting for clean integration into your async JavaScript codebase.
Does this tool actually execute the network request?
No. The converter strictly performs static syntax translation from cURL commands to JavaScript fetch() snippets. No network requests are dispatched, preventing accidental API calls or rate-limit consumption.
Can I convert multiline cURL commands with shell backslashes (\)?
Yes. Developer documentation (like Stripe, Twilio, and OpenAI) commonly uses terminal backslashes ('\') for multiline commands. The converter automatically normalizes multiline shell formatting into a clean single command before parsing.
How do I handle authentication tokens when using the generated code?
Header flags containing Authorization tokens (e.g., Bearer tokens or API keys) are placed directly into the headers object of the fetch snippet, where you can replace them with your frontend environment variables.
