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, ruby, rust, csharp, elixir, dart, matlab and a few more.

Install the command line tool with

$ npm install --global curlconverter

Install the JavaScript library for use in your own projects with

$ npm install --save curlconverter

curlconverter requires Node 12+.

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

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

I'd rather write programs to write programs than write programs.

First, make sure you're running Node 12 or greater.

If you add a new generator, you'll need to

• export it in index.ts
• update the list of supported languages in cli.ts (or it won't be accessible from the command line)
• add it to test-utils.ts (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
• run npm run gen-test post_with_headers to save the result of converting that file to test/fixtures/<language>/ with a matching filename but different extension like post_with_headers.py
• modifying the parser in util.ts or the generators in src/generators/ and re-run npm run gen-test until your test is converted correctly
• run npm test to make sure the new test passes

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

You can run a specific test with:

npm test -- test_name

where test_name is a file (with or without the .sh extension) in test/fixtures/curl_commands/

You can run only the tests for a specific language generator with:

npm test -- --language python
