request-options-gen

JS Library to generate options for request library by templates files

Install

npm install --save request
npm install --save request-options-gen

Super simple to use:

var rog = require('request-options-gen');
var request = require('request');

var options = rog.gen({
  basePath: 'tests/data',
  path: 'reqres/list-users'
});

console.log('Options: ');
console.log(JSON.stringify(options));

request(options,  function (error, response, body) {
  console.log('\nBody: ');
  console.log(JSON.stringify(JSON.parse(body)));
});

Will process the following files with this template folder:

♦
└┄ ▼ tests
   └┄ ▼ data
      ├┄ ▼ reqres
      │  ├┄ ▼ list-users
      │  │  ├┄ • qs.txt

      │  ├┄ • default-headers.txt
      │  └┄ • init-config.js
      ├┄ • config.js
      └┄ • generic-headers.txt
