Options

var api = require('@request/api')
var request = api({
  // required
  type: 'basic', // or 'chain'
  // required
  define: {
    // HTTP request function
    // that accepts @request/interface options object

  },
  // optional
  config: {
    // define your own methods and method aliases
  }
})

Basic API

Chain API
