Hudson Taylor is a set of libraries for making awesome microservices

'use strict'

var Client = require('../lib/client')
var Transports = require('../lib/transports')
var Service = require('../lib/service')
var s = require('ht-schema')

var number = 10
var multiplyBy = 5

// Make sure you pass the same instance
// of Transports.Local to both Service
// and Client or else this won't work!
var mathTransport = new Transports.Local()

var mathService = new Service(mathTransport)

mathService.on('multiply', s.Object({
  number: s.Number(),
  by: s.Number()
}), function (data, callback) {
  callback(null, data.number * data.by)
})

var client = new Client({
  'math': mathTransport
})

// If ALL of your services specified
// use local transports, you do not need
// to call connect here either.
client.connect(function (err) {
  if (err) {
    console.error('There was an error connecting to services:')
    console.error(err)
    process.exit(1)
  }

  client.call('math', 'multiply', {
    number: number,
    by: multiplyBy
  }, function (err, response) {
    if (err) {
      console.error('An error occured multiplying your number!')
      console.error(err)
      process.exit(1)
    }

    console.log('%d * %d = %d', number, multiplyBy, response)
  })
