r2curl

Background

• r2curl was inspired by @delirius325/axios-curlirize.
• axios-curlirize is very convenient. but works as a middleware for axios, and I think this part is black box logic
  • it contains potentially asynchronous concurrency issues and difficult-to-manage elements.
• So I created a new 'Request to cURL' package that is completely independent of the dependencies of axios.

Feature

• Generates cURL commands completely independently from the outside of the request wrapper package.
• Provides additional options involved in generating the cURL command.
• It will be updated soon to be available in packages like node-fetch or request.

Roadmap

• axios
  • AxiosRequestConfig
  • AxiosResposne
• node-fetch
• request
• ...

Install

npm install r2curl --save

Usage

axios

AxiosResponse

// if js, const r2curl = require('r2curl');
import r2curl from 'r2curl';

const response = await axios.get('https://google.com');
const curl = r2curl(response);

console.log(curl);
// stdout "curl -X GET 'https://google.com' -H 'Accept:application/json, text/plain, */*' -H 'User-Agent:axios/0.18.0'"

AxiosRequestConfig

// if js, const r2curl = require('r2curl');
import r2curl from 'r2curl';

// config as AxiosRequestConfig
const config = {
  url: 'https://google.com',
  method: 'POST',
  data: {
    caller: 'curl tester',
  },
  headers: {
    'Content-Type': 'application/json',
  },
};

const curl = r2curl(reqeustConfig);
console.log(curl);
// stdout `curl -X POST 'https://google.com' -H 'Content-Type:application/json' --data '{"caller":"curl tester"}'`

const response = await axios.request(config);

node-fetch

• update soon (target 0.2.0)
• see github project board

request

• update soon (target 0.2.0)

More r2curl Options

option.quote

• Determines the type of quota around the body and uri.
• default is single

import r2curl from 'r2curl';

// option as IR2CurlOptions.ts
const option = {
  /** Determines the type of quota around the body and uri. */
  quote: 'double',
};

const curl = r2curl(requestConfig, option);
console.log(curl); 

option.defaultContentType

• Determines the default Content-Type header value for POST and PUT requests.
• default is application/json; charset=utf-8
• Type is (enum) HTTP_HEADER_CONTENT_TYPE | string | false;
• If you give (boolean) false to defaultContentType, you can disable Content-Type Header.

import r2curl, { HTTP_HEADER_CONTENT_TYPE } from 'r2curl';

// const optionUsingEnum = {
//   defaultContentType: HTTP_HEADER_CONTENT_TYPE.TEXT,
// };
const option = {
  defaultContentType: 'application/json5',
}
const request: AxiosRequestConfig = { url: 'https://google.com', method: 'POST' };

const curl = r2curl(config, option);
console.log(curl); 
// output: curl -X POST 'https://google.com' -H 'Content-Type:application/json5

option.forceBody

• Accept Body all HTTP Method.
• By default, Body is not allowed in GET and DELETE methods.
• However, some services such as ElasticSearch should be able to use the Body as a GET method. At this point, use this option to activate the Body.

import r2curl from 'r2curl';

const config: AxiosRequestConfig = {
  url: 'https://google.com',
  method: 'GET',
  data: {
    caller: 'https://github.com/uyu423/r2curl',
    sorry: true,
  },
};

const option = {
  forceBody: true,
}

const curl = r2curl(config, option);
// output: 'curl -X GET \'https://google.com\' --data \'{"caller":"https://github.com/uyu423/r2curl","sorry":true}\''
