3. The problem with long URLs…

B6E6-C2D9C2AB2BE8}

5. A terrible user experience at best.

6. But worse, a missed opportunity…

7. Every URL you send a customer, partner,
prospect is an opportunity to make a
branding impression.

11. neurl.it v0.1
• Shorten/Create
– When I submit a long, ugly URL to the create API, I
should get back a neurl.
• Redirect
– When I submit a neurl to the submit API, my
request should be automatically redirected.
• Hits
– When I submit a neurl to the hits API, I should get
back the number of hits/redirects for that neurl.

17. What is NodeJS?
• Server-side scripting framework based on the
Google V8 engine accessible via JavaScript.
• Asynchronous by nature, making it very
performant.
• Growing community and industry support,
including libraries (modules).

18. Hello Node
// Say Hello via Console
console.log("Hello World");

19. Hello Node
// Load the http module to create an http server.
var http = require('http');
// Configure our HTTP server to respond with Hello World to all
requests.
var server = http.createServer(function (request, response) {
response.writeHead(200, {"Content-Type": "text/plain"});
response.end("Hello Worldn");
});
// Listen on port 8000
server.listen(8000);
// Put a friendly message on the terminal
console.log("Server running at http://127.0.0.1:8000/");

20. NodeJS Fundamentals
• Node Package Manager (NPM) – Package manager
for downloading and referencing thousands of
NodeJS modules.
• Package.json – Captures information about
modules (including your project/module) and
dependencies.
• Server.js – Typical entry point to a NodeJS
application but any .js will do.
• Running NodeJS apps is as simple as this:
> node server.js

21. Client
Event Loop
Callback
Workers
IO
Response

22. Why Node?
• My goal is not to convince you to use NodeJS
over ASP.NET, Web API, WCF or any other
back-end framework.

23. Why Node?
• Rather, I want to show you a practical example
of what you can do with NodeJS.
• Alternate implementations, either in NodeJS
or other platforms, frameworks and languages
is left as an exercise to the reader.
