Example

process single file (assumes HAR Request Object Format):

EXAMPLE: my-api-endpoint.json

{
  "method": "POST",
  "url": "http://mockbin.com/request",
  "httpVersion": "HTTP/1.1",
  "queryString": [
    { "name": "foo", "value": "bar" },
    { "name": "foo", "value": "baz" },
    { "name": "baz", "value": "abc" }
  ],
  "headers": [
    { "name": "Accept", "value": "text/plain" },
    { "name": "Content-Type", "value": "application/json" },
    { "name": "X-Foo-Bar", "value": "Baz" }

    { "name": "foo", "value": "bar" },
    { "name": "bar", "value": "baz" }
  ],
  "postData": {
    "mimeType": "application/json",
    "text": "{\"foo\": \"bar\"}"
  }
}

httpsnippet my-api-endpoint.json --target php --output ./snippets

$ tree snippets
snippets/
└── my-api-endpoint.php

process multiple files:

httpsnippet /*.json --target node --client native --output ./snippets

$ tree sources/

Module

var httpsnippet = require('httpsnippet');

var snippet = new httpsnippet({
  method: 'GET',
  url: 'http://mockbin.com/request'
});

// generate cURL output
console.log(snippet.convert('curl', {
  indent: '\t';
}));

// generate nodeJS output
console.log(snippet.convert('node'));

// generate PHP output
console.log(snippet.convert('php', 'curl'));

Documentation

At the heart of this module is the HAR Request object as the http request description format, please review some of the sample JSON HAR Request objects in test fixtures, or read the HAR Docs for more details.

Output Targets

output targets are simple modules that expose a constructor (which handles the transformation) and a meta info property.

module.exports = function (opts) {
  // optionally process `opts` object for target specific configuration
  // 
  // process `this.source` object
  // 
  // return processed output as string
};

module.exports.info = {
  key: 'curl',
  title: 'cURL',
  link: 'http://curl.haxx.se/',
  description: 'curl is a command line tool and library for transferring data with URL syntax',
  extname: '.sh'
};
