curl-string

request -> cURL string

Debug API calls by printing human-readable cURL strings

Motivation

• cURL is the most well-known command line tool for API calls
• Logging cURL commands to the console helps debug API calls
• cURL commands are easy to read (when printed in human readable format)
• cURL commands can be pasted into a terminal or Postman

Usage

import curlString from 'curl-string';
const debug = true;

const url = 'http://example.com';
const options = {
  method: 'post',
  headers: { accept: 'application/json', 'accept-language': 'en' },
  body: { hello: 'world' }
};

if (debug) {
  console.log(curlString(url, options));  
}
// make real call here, e.g. fetch(url, options);

Output:

Advanced Usage

curlString supports an optional 3rd parameter config object:

const curlStringOptions = { colorJson: true, jsonIndentWidth: 2}; // (these are the defaults)
const str = curlString(url, options, curlStringOptions);
