Generate code from cURL commands

Project README

curlconverter

curlconverter transpiles curl commands into programs in other programming languages.

$ curlconverter --data-raw "hello=world" example.com
import requests

data = {
    'hello': 'world',
}

response = requests.post('http://example.com', data=data)

You can choose the output language by passing --language <language>. The options are python (the default), javascript/node, node-axios, php, go, java, r, rust, elixir, dart, matlab and a few more.

Install the JavaScript library for use in your own projects with

$ npm install --save curlconverter

curlconverter requires Node 12+.

Usage

The JavaScript API is a bunch of functions that can take either a string of Bash code or an array

import * as curlconverter from 'curlconverter';

and return a string of code like:

}

response = requests.get('http://en.wikipedia.org/', headers=headers, cookies=cookies)

Note: you have to add "type": "module" to your package.json for the above example to work.

Make sure you're running Node 12 or greater. The test suite will fail on older versions of Node.js.

If you add a new generator, make sure to update the list of supported languages in src/cli.ts or else it won't be accessible from the command line. Further, you'll want to update test.js and index.js for your new generator to make it part of the testing.

If you want to add new functionality, start with a test.

Create a file containing the curl command in test/fixtures/curl_commands with a descriptive filename like post_with_headers.sh
Create a file containing the output in test/fixtures/python/ with a matching filename (but different extension) like post_with_headers.py
Run tests with npm test.
If your filenames match correctly, you should see one failing test. Fix it by modifying the parser in util.ts or the generators in src/generators/

The parser generates a generic data structure consumed by code generator functions.

You can run a specific test with:
