Ember applications are built around an MVC model that prescribes Models, Views, Controllers, and Routes for managing persistence, DOM, application state, and URLs. In an ambitious enough app, that model may fail to cover the whole problem space. Fear not, for in this presentation you will learn how to use Ember’s container and dependency features to move beyond MVC, as well as learning how they tie Ember internals together.

ECMAScript6: Novedades y navegadores que dan soporte a ECMAScript6. Presentado por ings.: Alex Adriá y Mario García

AngularJS uses a compile function to parse HTML into DOM elements and compile directives. The compile function sorts directives by priority and executes their compile and link functions to connect the scope to the DOM. It recursively compiles child elements. This allows directives to manipulate DOM elements and register behavior.

Topics covered: Closure, Callback, Module Pattern, Cascading, Curry, Inheritance, Pseudo Classical, Prototype

This document provides an overview of Backbone.js and how it can be used to build dynamic web applications. It discusses the main Backbone components: - Models represent single data objects and can be validated. - Collections hold ordered sets of models and can fetch data from the server. - Views handle the display and interaction of data from models and collections. - Routers map URLs to functions that control the application flow. The document then gives an example of using Backbone to build a simple shopping cart application with Products and Cart views, demonstrating how the components work together.

1. The document discusses strategies for optimizing software costs, including the costs of introduction, change, and ownership over the lifetime of a project. 2. It emphasizes focusing on optimizing for cost of introduction early on, as this cost is relatively easy to optimize and loses relevance over time. However, cost of change increases exponentially and is most important to optimize for longer-term projects. 3. Cost of ownership involves ongoing maintenance and allows balancing the costs of introduction and change by selectively taking ownership of only necessary logic through techniques like testing and refactoring.

The document describes how to create an Android project in Eclipse to call a JSON web service. It includes: 1. Creating a new Android project called "TestJSONWebService" targeting Android 2.2 with an activity called "TestWebServiceActivity" and package name "parallelminds.webservice.com". 2. The main activity, TestWebServiceActivity, makes a call to the web service using the callWebService() method and parses the JSON response to populate a list view. 3. A second class, CallWebService, implements the call to the web service and returns the JSON response.

The document discusses the evolution of the author's views on JavaScript and front-end frameworks. It begins by expressing dislike for JavaScript but acknowledging the need for it. Various frameworks like Backbone, Angular, and Ember are explored but found lacking. React is then introduced and praised for its declarative and composable approach similar to HTML. The author comes to understand JSX and how React implements unidirectional data flow to separate the UI from data logic. This allows building full-stack applications with React handling both client and server rendering based on shared intentions, state, and data flow patterns.

The document discusses several design patterns in Ruby including Template Method, Strategy, Observer, Factory, Builder, and Adapter patterns. For each pattern, it provides a code example to illustrate how the pattern can be implemented in Ruby. It focuses on explaining how each pattern works and how it can be applied to solve common programming problems.

The document provides an overview of AngularJS dependency injection and the $provide service. It explains the differences between providers, factories, services, values, constants, and decorators. It describes how $provide registers these items in the providerCache and instanceCache and instantiates them lazily through the $injector. Circular dependencies can cause errors since items point to each other before being fully instantiated.

The document provides an overview of modern web development frameworks and libraries from 2006 to 2015. It discusses: - Early frameworks like jQuery that provided cross-browser APIs but had tight coupling with HTML. - AngularJS which introduced two-way data binding but had slow dirty checking. - Backbone.js which used a true MVC pattern with jQuery-like views but had a complicated data binding system. - React which introduced one-way data flow and the virtual DOM for performance. It requires changing one's mindset. - The adoption of reactive programming concepts which treat all code as streams of events. - The evolution of frameworks to incorporate ideas from React while new libraries emerged

1) The document discusses the author's experience building their own node.js web framework, including their background with other technologies like Ruby on Rails. 2) It describes the key features of their framework, such as MVC structure, middleware support, asset packaging, and command line tools. 3) The author explains that they rolled their own framework to learn more about how frameworks work, have more control over the technology stack, and because node.js performance is better than Ruby on Rails. They emphasize that building the framework was a fun learning experience.

Talk on Rails and JavaScript and how JavaScript should be written, structured, separated from the HTML etc.

Is your web app drowning in a sea of JavaScript? Has your client-side codebase grown from "a snippet here and there" to "more JavaScript than HTML"? Do you find yourself writing one-off snippets instead of generalized components? You're not the only one. Learn about a handful of strategies you can use to keep your JavaScript codebase lean, modular, and flexible. We'll cover all the major pain points — MVC, templates, persisting state, namespacing, graceful error handling, client/server communication, and separation of concerns. And we'll cover how to do all this incrementally so that you don't have to redo everything from scratch.

This document discusses metaprogramming in JavaScript using ES6 features. It begins by defining metaprogramming as programming that treats programs as data. It explores reflection within implementation using Symbols, reflection through introspection using the Reflect object, and reflection through intercession using Proxies. For frontend developers, it suggests Symbols could be used where constants are now used, and Reflect and Proxies could be used for monkey patching and modifying prototypes.

It also discusses how JavaScript allows first-class functions and functional programming. The document then covers how to properly manage scripts in WordPress using functions like wp_register_script, wp_enqueue_script, and wp_localize_script to internationalize scripts. It concludes by mentioning additional JavaScript topics to explore like closures and functional programming.

This document provides an overview of using the Backbone.js framework for client-side MVC applications. It discusses why Backbone is useful for structuring JavaScript applications, its core architecture including models, collections, views and routers. It also provides examples of how to convert jQuery code to use a Backbone-based approach and lists some real-world applications that use Backbone.

JavaScript is evolving with the addition of modules, platform consistency, and harmony features. Modules allow JavaScript code to be organized and avoid naming collisions. CommonJS and AMD module formats are used widely. Platform consistency is improved through polyfills that mimic future APIs for older browsers. Harmony brings language-level modules and features like destructuring assignment, default parameters, and promises to JavaScript. Traceur compiles Harmony code to existing JavaScript.

Javascript and first-class citizenry: require.js & node.js Javascript on web pages is ubiquitous and its problems are legendary. Javascript, seen as a second-class code citizen, is usually hacked together even by seasoned developers. New libraries (jQuery, prototype, backbone, knockout, underscore) and runtime tools (firebug, jasmine) look like they solve many problems - and they do. But they still leave poorly written code as just that. One key problem is that all javascript code lives globally and this results in poorly managed, tested and delivered code. In this session, I will illustrate that we can treat javascript as a first-class citizen using with require.js and node.js: it can be modular, encapsulated and easily unit tested and added to continuous integration cycle. The dependencies between javascript modules can also be managed and packaged just like in C# and Java. In the end, we can resolve many javascript difficulties at compile time rather than waiting until runtime.

The document discusses reasons why JavaScript does not suck, including that it is the most widely used functional programming language, supports lambda functions, objects, metaprogramming, and duck typing. It provides examples of the module pattern for encapsulation and prototype inheritance for object-oriented programming in JavaScript.

MongoDB is the trusted document store we turn to when we have tough data store problems to solve. For this talk we are going to go a little bit off the path and explore what other roles we can fit MongoDB into. Others have discussed how to turn MongoDB’s capped collections into a publish/subscribe server. We stretch that a little further and turn MongoDB into a full fledged broker with both publish/subscribe and queue semantics, and a the ability to mix them. We will provide code and a running demo of the queue producers and consumers. Next we will turn to coordination services: We will explore the fundamental features and show how to implement them using MongoDB as the storage engine. Again we will show the code and demo the coordination of multiple applications.

When you move beyond adding simple enhancements to your website with jQuery and start building full-blown client-side applications, how do you organize your code? At this month's Triangle JS Meetup, we'll take a look at patterns for application development using jQuery that promote the principles of tight encapsulation and loose coupling, including classes, the publish/subscribe paradigm, and dependency management and build systems.

The document discusses software architecture for node.js applications. It covers using a home-brewed MVC framework called COKE, implementing RESTful routing and validation, separating concerns between controllers, models, and views, using libraries to extract reusable code, and scaling node.js applications from a single server to multiple distributed services. It also discusses deployment strategies from single server with downtime to zero downtime across multiple instances.
