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

  1. Paste a curl command into the input field.
  2. Click Convert to generate a fetch snippet.
  3. Copy and paste the output into your codebase.
