Convert a cURL command into JavaScript fetch code.

Category: Dev Tools

When to use?

Use it to quickly move a cURL request copied from devtools or API docs into frontend code.

How to use

  • Enter the cURL command.
  • It analyzes the URL, method, headers, and body.
  • Copy the generated fetch code.

Input Explanation

Enter a command starting with curl and -X, -H, -d options.

Calculation Basis

It parses the command tokens to extract the URL, HTTP method, headers, and body, then reconstructs them as a fetch options object.

Usage Examples

  • Write API sample code - Convert a doc's cURL example into fetch code.
  • Quick pre-deploy check - Check inputs and output to reduce errors before dev/ops work.
  • Aid docs/reviews - Copy the result into dev docs, issues, or review comments.

Examples

  • curl -X POST -H "Content-Type: application/json" -d "{}" https://api.example.com → fetch code
  • A POST cURL command → fetch code with headers and body filled

Cautions

  • Generated output is for reference; test carefully before production use.
  • Specific specs or framework-only syntax may cause compatibility issues.
