cURL to fetch Guide
cURL is perfect for quick command-line API tests. But when moving into frontend or Node.js code, converting to `fetch` saves time and avoids manual rewrite mistakes.
What it is
- cURL is a command-line tool for making HTTP requests.
- A cURL to fetch converter transforms common flags into JavaScript request code.
Why developers use it
- It accelerates the transition from terminal tests to application code.
- Headers, method, and request body stay consistent across conversion.
- It reduces manual copy/paste errors in API integration work.
Example
curl command and equivalent fetch snippet
Input
curl -X POST "https://api.example.com/users" -H "Content-Type: application/json" -d "{\"name\":\"John\"}"Output
fetch("https://api.example.com/users", {
method: "POST",
headers: {
"Content-Type": "application/json"
},
body: "{"name":"John"}"
});How to use the tool
- Paste a curl command into the input field.
- Click Convert to generate a fetch snippet.
- Copy and paste the output into your codebase.
