The document provides an overview of Node.js, detailing its history, key features, and advantages such as non-blocking, asynchronous programming. It covers the evolution of Node.js since its inception in 2009, the introduction of important frameworks, and practical applications in web development. Additionally, it mentions resources for further learning and development tasks involving Node.js.
A Journey Begin with Node.js
- 2. Node.js In a simple word Node.js is a JavaScript on the server
- 3. Node.js Timeline 2009 - Node.js written by Ryan Dahl and using Google's V8 JavaScript engine - Package manager (npm) was introduced 2010 - Express framework), Socket.io (real-time engine)are started 2011 - Windows version relesed - Larger companies start using such as LinkedIn, Uber, etc. - hapi(framework) is born 2013 - Ghost blogging platform using Node.js - Koa (framework) introduced 2015 - The Node.js Foundation is born - IO.js is merged back into Node.js - npm introduces private modules 2016 - The io.js announce that developers switch back to Node.js 2017 - V8 introduces Node.js in its testing suite
- 4. Why Node.js • Open source • Platforms - Windows, Linux, Unix, Mac OS X, etc. • Asynchronous programming
- 6. Advantages • Node.js eliminates the waiting, and simply continues with the next request. • Node.js runs single-threaded, non- blocking, asynchronously programming, which is very memory efficient.
- 7. Handles A File Request PHP or ASP Node.js 1. Sends the task to the computer's file system. 2. Waits while the file system opens and reads the file. 3. Returns the content to the client. 4. Ready to handle the next request. 1. Sends the task to the computer's file system. 2. Ready to handle the next request. 3. When the file system has opened and read the file, the server returns the content to the client.
- 8. Node.js File • Node.js files contain tasks that will be executed on certain events • A typical event is someone trying to access a port on the server • Node.js files must be initiated on the server before having any effect • Node.js files have extension ".js"
- 9. Web App Characteristic Node.js with all web characteristic such as Cookies, and Sessions
- 10. REST API REST stands for REpresentational State Transfer. REST is web standards based architecture and uses HTTP Protocol. HTTP methods are commonly used in REST based architecture. • GET • PUT • DELETE • POST
- 11. Move on Practical Task
- 12. IDE Cloud 9 IntelliJ IDEA WebStorm Komodo IDE Koding Eclipse WebMatrix Sublime Text Atom Brackets Codenvy Aptana CodeLite Visual Studio Code NetBeans Codelobster
- 14. Hello World
- 15. Demo Tasks
- 16. Create A Module
- 17. Books References Node.js the Right Way: Practical, Server-Side JavaScript That Scales by Jim Wilson Learning Node.js: A Hands-On Guide to Building Web Applications in JavaScript by Marc Wandschneider Beginning Node.js by Basarat Syed
