common infrastructure tasks, so you can
focus on writing the really important part
of the bot – your business workflows.

35. OK, LET ME SHOW YOU

36. var botBuilder = require('claudia-bot-builder')
module.exports = botBuilder(function(message) {
return 'Hi there! You sent “' + message.text + '“'
})

37. const botBuilder = require('claudia-bot-builder')
module.exports = botBuilder(message =>
`Hi there! You sent “${message.text}”`)

38. • AMAZON WEB SERVICES ACCOUNT
• Node.js (version 4.3.2 is preferred)
• Install Claudia and Claudia Bot Builder from NPM
