OpenSource API Server based on Node.js API framework built on supported Node.js platform with Tooling and DevOps. Use cases are Omni-channel API Server, Mobile Backend as a Service (mBaaS) or Next Generation Enterprise Service Bus. Key functionality include built in enterprise connectors, ORM, Offline Sync, Mobile and JS SDKs, Isomorphic JavaScript and Graphical API creation tool.

7. What’s needed ? Legacy services need to fit too !
API centric Enterprise
Thousands to Millions of devices connecting to business APIs
creating the new user experience
APIs for each device, each app, each screen. Optimized for bandwidth & battery,
adjusting to each device’s capabilities

8. Why Node?
8
Node is FAST
…and highly concurrent!
Node is perfect for APIs
Node is JavaScript

9. What is Node.js?
• Asynchronous, event-driven, non-blocking I/O platform that is perfect for real-time,
data-intensive applications.
• Single thread of execution
• Built on Chrome’s JavaScript runtime engine, V8
• Uses Libuv, a high performance evented I/O library that works on Linux and
Windows (faster than Libev)
while there are still events to process:
e = get the next event
if there is a callback associated with e:
call the callback

10. Threads
Don’t Wait !

12. Why Node.js?
• Lots of JavaScript programmers out there (>62K)
• Very large and active developer community
• Has the most modules (90K > Java)

13. Why Node.js?
LinkedIn moved from Rails to Node.js
– Cut down servers by 90% (30  3)
– Lower memory overhead and up to 20X faster
PayPal migrated to Node.js from Java:
– Reduce development time by >50%
– 2X speed of delivery with less than existing resources
– 33% lesser lines of code
– 40% fewer files
Groupon displaced Ruby and Java with Node.js across the board:
– 50% improvement in page response times
– Agile builds and deploys

21. Error tracking/recovery
var http = require('http');
var cache = {};
function curl(url, cb) {
if (cache[url])
return cb(null, cache[url]);
var data = '';
http.get(url, function(res) {
res.setEncoding('utf8');
res.on('data', function(s) {
data += s;
});
res.on('end', function() {
cache[url] = data;
cb(null, data);
});
res.on('error', function(err) {
cb(err);
});
});
}
// Usage:
curl('http://www.google.com', console.log); 21

22. Error tracking/recovery
var http = require('http');
var cache = {};
function curl(url, cb) {
if (cache[url])
// WRONG: Synchronous callback
return cb(null, cache[url]);
var data = '';
http.get(url, function(res) {
res.setEncoding('utf8');
res.on('data', function(s) {
data += s;
});
res.on('end', function() {
cache[url] = data;
cb(null, data);
});
// WRONG: are you sure that 'end' and 'error' are mutually exclusive?
res.on('error', function(err) {
cb(err);
});
});
// WRONG: the request object may emit 'error'
}
