JSConf US 2014: Building Isomorphic Apps
Slides from Spike Brehm's talk at JSConf US 2014. Topics include the etymology of "Isomorphic JavaScript", examples is isomorphic apps in the wild, reasons behind the growing trend towards isomorphic apps, and how to build an isomorphic module using Browserify & NPM.
Building Isomorphic Apps (JSConf.Asia 2014)
Over the past year or so, we’ve seen the emergence of a new way of building JavaScript web apps that share code between the web browser and the server, using Node.js — a technique that has come to be known as "isomorphic JavaScript.” There are a variety of use cases for isomorphic JavaScript; some apps render HTML on both the server and the client, some apps share just a few small bits of application logic, while others share the entire application runtime between client and server to provide advanced offline and realtime features. Why go isomorphic? The main benefits are performance, maintainability, reusability, and SEO.
This talk shares examples of isomorphic JavaScript apps running in the wild, explore the exploding ecosystem of asset building tools, such as Browserify, Webpack, and Gulp, that allow developers to build their own isomorphic JavaScript apps with open-source libraries, demonstrate how to build an isomorphic JavaScript module from scratch, and explore how libraries like React and Flux can be used to build a single-page app that renders on the server.
Integrating Browserify with Sprockets
This document discusses integrating Browserify and CommonJS dependency management into Rails' asset pipeline Sprockets. It describes:
1) Limitations of Sprockets for managing JavaScript dependencies and the benefits of using Browserify and CommonJS.
2) How to integrate Browserify into Sprockets using a custom Tilt template that runs Browserify to bundle dependencies.
3) Enhancing the build pipeline to transpile ES6 code using a Browserify transform.
Node PDX: Intro to Sails.js
Sails.js makes it easy to build custom, enterprise-grade Node.js apps. It is designed to resemble the MVC architecture from frameworks like Ruby on Rails, but with support for the more modern, data-oriented style of web app development. It's especially good for building realtime features like chat.
In Pursuit of the Holy Grail: Building Isomorphic JavaScript Apps
This document discusses isomorphic JavaScript, which allows JavaScript code to run on both the client and server sides. It explains that isomorphic JavaScript is environment-agnostic and does not depend on browser- or server-specific properties. Popular libraries like Handlebars, Backbone, and React can be used isomorphically. Building isomorphic apps improves performance, enables search engine crawling of single-page apps, reduces code duplication, and increases flexibility. The document outlines how tools like Browserify and build systems like Grunt can be used to bundle code for both environments.
Ruby Sapporo Night Vol2
This document is about Ruby on Rails. It introduces RubySapporo and provides information about Ruby and Rails. Key points discussed include how Rails uses conventions over configuration, Don't Repeat Yourself principles, the MVC framework, and components like ActiveRecord and controllers. Links are provided to resources about Ruby, Rails, and an upcoming Sapporo workshop.
General Assembly Workshop: Advanced JavaScript
The document discusses isomorphic JavaScript, which allows JavaScript code to run on both the client and server. It provides examples using libraries like Underscore.js and Handlebars.js isomorphically. Frameworks like Meteor, Mojito, and Rendr are introduced that support building isomorphic apps. The benefits are around performance, SEO, and code maintainability. The presentation concludes with a demo of building features into an sample isomorphic blog application.
Merb Presentation
Merb is a web framework for Ruby similar to Rails but with fewer opinions. It is made up of three main parts - core, more, and plugins. Core provides basic routing and controllers, more adds functionality like views, and plugins provide additional features. Merb focuses on being lightweight, thread-safe, and modular while still providing the functionality needed for full-stack web development.

A Toda Maquina Con Ruby on Rails
Ruby is a dynamic, multi-paradigm programming language that is easy to read and write. It was influenced by Perl, Smalltalk, Lisp, C and other languages. Ruby on Rails is a web application framework built on Ruby that follows conventions over configurations and the MVC pattern. Rails emphasizes code reuse, easy maintenance, and rapid development of database-backed web applications.
Building Isomorphic JavaScript Apps - NDC 2015
This document discusses isomorphic JavaScript applications. Isomorphic apps allow developers to write code that runs both on the server and client using the same JavaScript. This avoids maintaining separate codebases and allows search engines to index content rendered on the server. The document outlines how isomorphic apps handle rendering, routing, data fetching and modules in a consistent way across server and client. It provides an example of building a simple isomorphic app and demonstrates core concepts like rendering, routing and data fetching.
The Evolution of Airbnb's Frontend
Over the last few years, Airbnb’s frontend architecture has evolved to keep pace with the rapid advancement happening the JavaScript world. Starting as a humble Rails 2 + Prototype.js app in 2008, the frontend stack powering airbnb.com has gone through a few revisions, including a push towards single-page app architecture with Backbone.js and Handlebars.js, an adventure into isomorphic JavaScript with Rendr (our library for using Node.js to server-render Backbone SPAs), and most recently, a move toward React.js and a re-envisioning of our build pipeline to take advantage of CommonJS, ES6, and a Node.js-based transform system. Spike Brehm, software engineer on the @AirbnbNerds team, will walk through how we approached and executed on these changes. Plus, get excited to see a preview of our new approach to isomorphic JavaScript, allowing us to server-render React components from our Rails app.
Spike Brehm is a software engineer at Airbnb who specializes in building rich web experiences. As a JavaScript nerd, he has spent the last few years shipping web apps and prototyping Airbnb’s front-end stack, experimenting with “isomorphic JavaScript” — apps that have the flexibility to run on both the client and sever using the same codebase.
Isomorphic JavaScript: #DevBeat Master Class
1) Isomorphic JavaScript allows code to run on both the client and server by being environment-agnostic or shimmed for different environments.
2) It improves performance by enabling faster initial page loads and improves SEO by allowing search engines to crawl single page apps.
3) Popular libraries like Underscore, Backbone, Handlebars, and React can be used isomorphically, and isomorphic applications exist on a spectrum from sharing small parts of code to entire applications.
Isomorphic JavaScript with Nashorn
Isomorphic JavaScript applications can share the same code and run on both the front end and back end. It is also a spectrum containing applications that share minimal bits of validation logic with ones that share a bulk of the application code. Nashorn is a new JavaScript engine for Java that was released with Java 8. The Nashorn JavaScript engine makes isomorphic web apps on the JVM possible by allowing the exact same browser code to run on the server. This enables us to achieve the don’t-repeat-yourself (DRY) principle, by reducing repetition in a multitier architecture. This presentation covers the key concepts, rationale, and categories of Isomorphic JavaScript and how it makes your large applications maintainable.

- Rails uses conventions over configurations, don't repeat yourself (DRY) principles, and an opinionated philosophy. It provides a directory structure, environment modes, and generators to quickly develop applications.
- The document provides an example of generating a bookmarks application with models, views, controllers, validations, associations, and AJAX functionality using Rails.
Introduction to Rails - presented by Arman Ortega
This document provides an introduction to Ruby on Rails presented by Arman Ortega. It outlines what will be covered including an overview of Ruby and Rails, the concept of convention over configuration in Rails, and performing CRUD (create, read, update, delete) operations. It then demonstrates creating a sample blog application in Rails and provides links for additional learning resources.
Static Code Analysis For Ruby
This is my presentation on Shanghai on Rails at 3.20. It introduces static code analysis for ruby, tells you a pattern to analysis ruby code and gives you some examples that how rails_best_practices analysis rails codes.
Ruby on Rails Presentation
Ruby on Rails is a web application framework that is designed to make programming web applications easier and more enjoyable. It includes features like an object-relational mapper called Active Record that allows database rows to be represented as objects, conventions that reduce configuration, and support for test-driven development. Rails is built on Ruby, an interpreted object-oriented programming language, and aims to be programmer friendly and allow powerful applications to be built quickly. Several experts praise Rails for lowering the barriers to entry for programming and being a well-thought-out framework.
Create a new project in ROR
The document summarizes new features in Rails 3.1 beta, including asset handling changes where JavaScript and CSS files are now placed in app/assets, identity maps to improve performance of object loading, simpler database migrations that use a single change method, and improved test output formatting. It also discusses installing Rails 3.1 in a isolated gemset and using Sass and CoffeeScript as default asset compilers.

Instruments ruby on rails
Ruby on Rails is a web framework that allows for rapid development through its built-in tools and modular structure. It incorporates principles of quality code, fast development processes, and reliable code. The framework uses generators to quickly create application components and includes various object-relational mappers to interface with different database systems. Testing and deployment are also streamlined through built-in tools and external utilities like Rake and Capistrano. Popular sites like Twitter, SlideShare, and Basecamp were all built using Ruby on Rails, demonstrating its capabilities for powering large-scale web applications.
Intro to Rails and MVC
Ruby on Rails is an open-source web application framework written in Ruby. It was first released in 2004 and emphasizes convention over configuration, and is designed to make programming web applications easier. The core dependencies needed to use Rails are Ruby, RubyGems, Rails, a database, and tools like Git for version control. Rails uses the MVC pattern with ActiveRecord for models, ActionView for views, and ActionController for controllers.
Practical Intro Merb
The document provides an introduction to the Merb web framework, which is similar to Ruby on Rails but aims to be lighter, more extensible, and faster. It discusses Merb's ideology of keeping the core small and code simple. Key components like routing, views, and plugins are described. Performance tests show Merb using less memory than Rails but slower response times. The author concludes Merb may be worth considering for small tools or limited memory apps, but issues remain with speed on JRuby.

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdf
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:
