cURL to JavaScript Fetch
How to Use the cURL to JavaScript Fetch Converter
Paste a cURL command and convert it into JavaScript Fetch code. The converter maps the request URL, method, headers and compatible body data into a fetch() call that is easier to use in browser or JavaScript application code.
Practical Example
A cURL POST request with a JSON Content-Type header and a small JSON body can be transformed into fetch(url,{method:’POST’,headers:{…},body:…}).
Factors That Affect the Result
Shell quoting, multipart uploads, authentication headers, redirects, compressed data and advanced cURL flags can require manual adjustment after conversion. Always review generated code before production use.
Frequently Asked Questions
Does every cURL option have a Fetch equivalent?
No, some command-line-specific options do not map directly to browser Fetch.
Are headers preserved?
Compatible request headers are normally converted into the Fetch headers object.
Should generated code be reviewed?
Yes, especially for credentials, file uploads and environment-specific behavior.
