Node.js is a compelling platform that is quickly spreading from startups to the enterprise. Node.js strategically unites developers of all backgrounds through the common language of JavaScript. Why should you learn Node.js and where do you start? You will come away from this talk with the evidence to support Node.js, and tools you need to be productive. We will walk through a typical workflow of creating and debugging a web application. You will learn how easy it is to deploy, including Microsoft Azure. We'll also look at popular frameworks and modules, and other learning resources to give you the best start.

57. Deploying
• Don’t include node_modules folder
• …unless you create builds for specific targets
• Azure is super-easy
• Windows
– iisnodefor web apps
– winserfor services
• Linux – forever

58. Hosting Node.js on Azure
• New Node JS Empty Site
• Connect to repository
• reverentgeek.com/hosting-node-js-on-microsoft-
azure/

59. Recommended toolbox
Package What it do, yo
lodash JavaScript utilities
when JavaScript promise library
async async/parallel execution
request (or rest) http client
gulp build engine, test runner
socket.io sockets, real-time
node-inspector Debugging
mocha test framework
chai TDD/BDD assertion library
sinon spies, stubs, mocks

60. Node frameworks
MVC
• Express
• hapi
• Meteor
• Sails
API
• Restify
• LoopBack
• Autohost + Hyped

61. Edge.js
• Run .NETin-process
• …including F#, ADO.NET,Python,
and Powershell
• Execute inline code, files, or
assemblies
• Alternative to writing native
modules in C
• .NET4.5 or Mono 3.1

62. What can Edge.js do?
• Leverage existing .NET investment
• TFS, SharePoint, Exchange, etc.
• Active Directory
• Hardware (e.g. camera, microphone,
printer, win32)
• Video encoding, or other CPU-intensive
work
• Powershell

63. Node.js Integration Strategies
• Node.js as proxy
• Edge.js for .NET
• request module to call APIs
• Messaging (e.g. RabbitMQ, Azure Service Bus)
