Essential Node.js for Web Developers from Developer Week 2013
1 like1,138 views
This document discusses Node.js and its suitability for web development. It describes Node.js as a platform built on Chrome's JavaScript runtime that uses non-blocking I/O and event-driven programming to enable fast and scalable network applications. The document emphasizes Node.js' focus on I/O-bound real-time applications and lists some of its capabilities like serving files and forms, server-side mashups, writing files, HTTP authentication, sockets programming, and MVC routing with many available libraries to support development.
Essential Node.js for Web Developers from Developer Week 2013
- 1. Essential Node for Web Developers Mike Amundsen Principal API Architect Layer 7 Technologies @mamund 1
- 2. Preliminaries Mike Amundsen Web Architect, Author, Presenter Software Explorer Principal API Architect, Layer 7 Technologies 2
- 3. Last Project Building Hypermedia APIs w/ HTML5 & Node (November 2011) Methodology for writing/maintaining business-level APIs in the cloud. Real solutions for real use-cases. Three Servers, Six Clients, 200+ pages. 3
- 4. Next Project RESTful Web APIs (Summer 2013) Co-author with Leonard Richardson Follow up to Richardson/Ruby’s RESTful Web Services (2007) Focus on scaling up application-level interoperability with hypermedia Beyond HTML, XML, and JSON is … 4
- 5. Let's start with a bit of Philosophy... 5
- 6. Unix Philosophy Write programs that do one thing and do it well. Write programs to work together. Write programs to handle text streams. - Douglas McIlroy 6
- 7. Node Philosophy (possible) • Write modules that do one thing and do it well. • Write modules to work together. • Write modules to handle streams and events 7
- 8. Eric S. Raymond's Design Rules "Rule of Diversity: Distrust all claims for one true way" -- Eric S. Raymond 8
- 9. Reminder: My Examples are NOT the "One True Way" 9
- 10. Essentially, Node is... "...a platform built on Chrome's JavaScript runtime for easily building fast, scalable network applications." 10
- 11. Node is… “Node is intended to be a very low-level library that facilitates higher-level extensions and abstractions in userland. It is more like C than it is like Python, and that is by design.” – Isaac Schlueter 11
- 12. And it's different because.... "Node.js uses an event-driven, non-blocking I/O model that makes it lightweight and efficient, perfect for data- intensive real-time applications that run across distributed devices." 12
- 13. So that means.... "Most of the applications we're writing today are heavily I/O bound. Because of the event-driven nature of JavaScript (and Node by extension), whatever you write with it is going to be very fast." - Guillermo Rauch (socket.io) 13
- 14. But does it run on my machine? "To build a diverse open source community, you need a wide platform," - Paul Querna, Rackspace 14
- 15. Essential NodeJS on a single slide (well, almost) 15
- 16. Ok, introduce me then... 16
- 17. Hello, Node! 17
- 18. Ok, but how do I deliver files? 18
- 19. Ok, but how do I deliver files using streams? 19
- 20. Not bad; how about HTML Forms? 20
- 21. Cool. Now how about a server-side mash-up? 21
- 22. Yeah, but how do you write files? 22
- 23. What about HTTP Authentication? 23
- 24. Ok, but where's that "sockets" stuff? 24
- 25. Alright, how about MVC & routing? 25
- 26. Hey, this is all 'async' & hard, right? 26
- 27. So are there lots of libraries? 27
- 28. So are there lots of libraries? 28
- 29. Bottom Line… While Node *is* Javascript, the ethos is closer to C/Unix Don’t get tied up in the “Evented IO” stuff; just write your code and enjoy Async is the future; learn to love the future. Get to know the NPM library; lots of good stuff there. Check out Shelly Power’s “Learning Node” book 29
- 30. So.... 30
- 31. Node.js... • “Low-level” Javascript • Non-blocking I/O • Cross Platform • Pages, Forms, Services, APIs, Sockets • MVC, Templates, ... • 1000s of available libraries • All Open Source Oh yeah, one more question... 31
- 32. Why not join the hipster Nod-ies? 32
