- 20. ©2015 Apigee Corp. All Rights Reserved. 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");

Editor's Notes
- #22: V8 - V8 compiles JavaScript to native machine code Single thread - Can’t scale vertically without using an additional module (use cluster, pm2 or strongloop pm)
