An Introduction to Node.JS

21. ©2015 Apigee Corp. All Rights Reserved.
What is NodeJS and who uses it?
• Cross-platform runtime environment for developing server-side
Web applications
• Built on Google Chrome's JavaScript V8 Engine
• Open source, completely free
• Event driven architecture and asynchronous I/O
• Operates on a single thread, using non-blocking I/O calls
• Package manager - npm
• Used by LinkedIn, IBM, Paypal, Netflix

22. ©2015 Apigee Corp. All Rights Reserved.
Node.JS First Class HTTP Server
• No need of maintaining separate threads for each open connection
• Create REST APIs very easily
• Asynchronous I/O

23. ©2015 Apigee Corp. All Rights Reserved.
Realtime apps and Async. Programming
Real time applications need non blocking I/O. This can be achieved by
Asynchronous programming which is commonly used in event based systems.
Async. Programming involves :
● Callbacks
● Promises
● Generators / yeilds (ES6)
● Async/ await (ES7)

24. ©2015 Apigee Corp. All Rights Reserved.
Example
//Synchronous
var result = database.query("SELECT * FROM hugetable");
console.log("query finished");
console.log("Next line");
//Asynchronous
database.query("SELECT * FROM hugetable", function(result) {
console.log("query finished");
});
console.log("Next line");
