curl-parser-js

Final javascript size is 2.58kB only!!

Simple javascript library to parse cUrl command to json object. Regex based matching without adding any complex parser code/library. Can be used in Node, in any frontend project or as standalone js file.

With the generated json object you may construct your own ajax call using your favourite library.

Usage

Standalone

Add your script tag

  <script src="https://cdn.jsdelivr.net/npm/[email protected]/dist/parse-curl.js"></script>

Parse your cmd

  const curlCmd = `curl 'http://server.com:5050/a/c/getName/?param1=pradeep&param2=kumar&param3=sharma'`;
  parse_curl_js.parse(curlCmd);

Standalone Demo on Codepen

Node/frontend projects who support modules importing.

import Curlparser from 'curl-parser-js';

Assume you have your `cUrl` command as a string constant

const curlCmd = `curl 'http://server.com:5050/a/c/getName'`;

### Execute parser to parse the curl command
const result = parsecurl(curlCmd);

console.log(JSON.stringify(result, null, 2)); will result in

{
 "url": "http://server.com:5050/a/c/getName",
 "headers": {}
}

cUrl command with query params

const curlCmd = `curl 'http://server.com:5050/a/c/getName/?param1=pradeep&param2=kumar&param3=sharma'`;
const result = parsecurl(curlCmd);

console.log(JSON.stringify(result, null, 2)); will result in

{
  "url": "http://server.com:5050/a/c/getName/?param1=pradeep&param2=kumar&param3=sharma",
  "headers": {},
  "queryString": {
    "param1": "pradeep",
    "param2": "kumar",
    "param3": "sharma"
  }
}

cUrl command with post data

 const curlCmd = `curl 'https://exampleserver.com/api/v5/tracktime/' -H 'origin: https://exampleserver.com' -H 'accept-encoding: gzip, deflate, br' -H 'accept-language: en-GB,en-US;q=0.8,en;q=0.6' -H 'authorization: JWT eyJiOjE1MTIyMTIyNzYsIm9yaiOjE1MTIyMTIyNzYsIm9yaJ9.eyJ2ZXJzaW9uIjoiMjciLCJleHAiOjE1MTIyMTIyNzYsIm9yaiOjE1MTIyMTIyNzYsIm9yaLCJ1c2VyX2lkIjo1MTAsImVtYWlsIjoibWFydWRodS5ndW5iOjE1MTIyMTIyNzYsIm9yam5hbWUiOiJtYXJ1ZGh1Lmd1iOjE1MTIyMTIyNzYiOjE1MTIyMTIyNzYsIm9yafQ._BuiOjE1MTIyMTIyNzYsIm9yadJ__2iOjE1MTIyMTIyNzYsIm9yaRTmNcW0' -H 'content-type: application/json; charset=UTF-8' -H 'accept: */*' -H 'referer: https://exampleserver.com/timeSheetChange' -H 'authority: exampleserver.com' -H 'user-agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_13_1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/61.0.3163.100 Safari/537.36' --data-binary '{"action":"Add custom time","data":"November 27, 2017 - December 03, 2017"}' --compressed`;
 const result = parsecurl(curlCmd);

console.log(JSON.stringify(result, null, 2)); will result in

Roadmap

1. Add plugins to generate request for different libraries.
