Backbone.js is a frontend MVC framework that is lightweight and flexible, allowing integration into existing projects and adding structure to JavaScript. React.js is a UI library for building interactive, stateful components. Backbone.js uses models, views and controllers while React focuses only on views. Backbone.js has an initial learning curve while React uses a virtual DOM for efficient re-rendering. Both support building large, data-driven applications but React advocates a one-way data flow between stores and views.

Backbone to React. What it says about awesome UI Code.
Why is writing React.JS code so simple? Why had writing Backbone.JS code become difficult for us at Server Density. What does this say us about good code vs great code?
In this presentation I cover 3 important concepts:
* Code simplicity vs complexity
* Code predictability
* Composability
Using real-world example I'll share what our 16 month journey migrating a large Backbone codebase, to a large React codebase has taught us.
Backbone.js with React Views - Server Rendering, Virtual DOM, and More!
11/18/2014 Seattle ReactJS meetup presentation -- http://www.meetup.com/seattle-react-js/events/216736502/
Abstract:
Ryan Roemer will discuss moving the view components of a conventional Backbone.js app to React and dive into many of the new and exciting facets of a reactive, virtual DOM-based view layer.
He will review the path leading up to https://github.com/FormidableLabs/notes-react-exoskeleton -- a lean, modern MVC app with nifty features like server-side rendering and transparent server/client-side routing.
Intro to React
React is a library for building user interfaces using components. It uses a virtual DOM for rendering components, which are pieces of UI defined as classes or functions. Components receive data via props and local state, and can be nested to build complex UIs. The component lifecycle includes mounting, updating, and unmounting phases. Data flows unidirectionally down the component tree. React has a vibrant ecosystem and community for continued learning.
Introduction to React JS
React is a JavaScript library for building user interfaces. It uses a component-based approach where UI is broken into independent, reusable pieces called components. Components are like functions that return markup describing part of a view. React uses a virtual DOM to efficiently update the real DOM by only making necessary changes. This improves performance by avoiding expensive DOM operations and minimizing DOM access. Components receive data and callbacks through properties and local state is updated using setState(), triggering a re-render of changed parts of the UI.

React.js
React.js is a JavaScript library that uses a virtual DOM to improve performance issues with traditional web development approaches that involved full page refreshes on data changes. It works by rendering the UI into memory first before writing to the real DOM, allowing it to selectively update parts of the real DOM for better efficiency. Key concepts in React include components, props, state, lifecycle methods, events, and immutability to facilitate fast re-rendering when data changes.

Introduction to react js
This document provides an introduction to ReactJS, including:
- Why React is simple, declarative, and allows building of composable components
- React's popularity, with over 900,000 downloads in the last month
- How React addresses issues with traditional web development through its use of virtual DOM and componentization
- An example component is demonstrated to show how to: render in JSX, make components dynamic and interactive through props and event handling, access the DOM through refs, and manage state.
BackboneJS and friends
BackboneJS is a JavaScript MVC framework that allows developers to focus on presentation logic on the client-side. It uses a standard MVC pattern with Models, Views, and Controllers. Backbone also includes utilities like Backbone.Router for single page applications, Backbone.View for handling DOM elements and events, and Backbone.Collection for working with lists of models. RequireJS helps manage dependencies between libraries, and Underscore provides useful functions for collections and utilities.
Backbone.js and friends
This document discusses the pros and cons of using the JavaScript library Backbone.js versus building a full-featured framework. It notes that while Backbone.js is only a code organizer and light library, developers want features of a full framework like session management and validation. Building a custom framework from scratch takes a lot of time and effort and is only 1/26 of what is needed for a real application. Frameworks like ExtJS provide more out of the box for less work than rolling one's own solution. The document advocates using Backbone.js and accepting its limitations rather than trying to re-invent the wheel by developing a full custom framework.
Introduction to React JS for beginners
- React is a JavaScript library for building user interfaces that uses a virtual DOM for faster re-rendering on state changes.
- Everything in React is a component that can have states, props, and lifecycle methods like render(). Components return JSX elements.
- Props are used for passing data to components in a unidirectional flow, while states allow components to re-render on changes.
- The render() method returns the view, accessing props and state values. Forms and events also follow React conventions.
Backbone js
Backbone.js is a popular JavaScript MVC framework that provides structure for single-page web applications. It includes models for managing application data, views for rendering UI components, and a router for handling navigation between views. Backbone promotes separation of concerns, giving each component clearly defined responsibilities. Models can communicate with servers via RESTful APIs or websockets to retrieve and sync data. Collections manage ordered sets of models and can also fetch data from servers. Views are used to render templates and interface with models. The router maps URLs to functions that control navigation between views. Overall, Backbone provides a useful framework for building structured, scalable client-side JavaScript applications.
[Final] ReactJS presentation
React JS is a JavaScript library for building user interfaces. It uses a virtual DOM to efficiently update the real DOM and render user interfaces from components. Components are reusable pieces of UI that accept input data via properties but maintain private state data. The lifecycle of a component involves initialization, updating due to state/prop changes, and unmounting. React uses a single-directional data flow and the concept of components makes code modular and reusable.
Backbone
Backbone.js is a JavaScript library that provides structure to applications by supplying models, collections, and views. It follows an MVC-like pattern, with models representing data, views handling display/interaction logic, and routers managing navigation. Backbone is lightweight and depends on Underscore.js for utility functions. Models manage data and can fetch/save to servers. Collections are ordered sets of models. Views display data and handle events. Routers map URLs to functions. Underscore provides over 100 helper functions for tasks like iteration, filtering, and more.
Vývojařská Plzeň - React
React is a JavaScript library for building user interfaces that was created by Facebook and Instagram. It aims to make interface development easier by making DOM manipulation faster and encouraging unidirectional data flow and reusable components. Some key reasons for its success include its small public API, emphasis on a data-down approach, cross-platform support, and growing community. React uses virtual DOM elements and components to build interfaces in a declarative way.

ReactJS is arguably the most popular Javascript framework around for web development today. With more and more teams exploring and adopting React, here is TechTalks presentation elaborating fundamentals of React, in a code along session
Planbox Backbone MVC
Migrating MVC to the Front-end using Backbone JS.
Planbox is a single-page web application for Agile project management. It was built using the traditional MVC stack with CodeIgniter (PHP) and jQuery (Javascript). AJAX was heavily used to update DOM elements to offer a dynamic user experience. UX logic code quickly became spread across Javascript and PHP. The application code base quickly became unmanageable and scaling functionality became difficult. Things had to change.
A decision was made to change architecture: bring all the UX logic in the front-end, and turn the back-end into an engine in charge of business logic.
This talk is about this experience. How we moved the MVC stack from the back-end to the front-end. How we used Backbone JS as the foundation of our front-end framework and built on top. How the backend became a black-box with a Restful API. What lessons we learned, what benefits we gained, and what reflections we made about the future of MVC in Javascript.
The Benefits of Using React JS for Web Development!
React JS is a popular library for building user interfaces that was created by Facebook in 2011. It allows developers to create reusable components to build dynamic and interactive applications. React uses a virtual DOM for rendering to improve performance and make code more consistent and stable. It also supports code reuse through components that can be built upon and manipulated through their internal logic.

Javascript frameworks: Backbone.js
1. Backbone.js is a lightweight JavaScript framework that brings structure to client-side code through an MVC pattern.
2. It separates presentation logic from business logic by defining Models, Collections, and Views. Models represent data, Collections hold lists of Models, and Views render the UI and handle events.
3. While Backbone.js allows building single page applications quickly, code can become disorganized without its structure. The framework encourages maintainable, loosely coupled code through its MVC implementation.
Introduction to Backbone.js
1. Backbone.js is a lightweight JavaScript library that adds structure to client-side code and makes it easy to manage concerns in an application.
2. It uses an MVC pattern with models to manage data, views to manage the UI display, and routers to manage client-side pages and links events to actions.
3. Backbone.js dependencies include Underscore.js and either jQuery or Zepto, but it does not replace jQuery which handles DOM interactions and events.
Managing JavaScript Dependencies With RequireJS
This document discusses how to manage JavaScript dependencies using RequireJS. It begins by showing the many different types of JavaScript dependencies that exist, such as libraries, frameworks, plugins, and custom code. It then outlines some of the problems that arise from having many script tags, including increased complexity. The document proceeds to explain how RequireJS uses an Asynchronous Module Definition (AMD) approach to define modules and their dependencies. It provides a code example of validating a mailing list signup form, breaking it into modules for jQuery, a validation plugin, and the main application script. Finally, it discusses how RequireJS can improve page load performance by loading scripts asynchronously on demand.
Workshop 22: React-Redux Middleware
The document discusses advanced Redux concepts including higher order components, middleware, and the decorator pattern. It provides examples of how middleware can be used to log actions, modify actions before they reach the reducer, and compose independent and reusable behaviors. Code samples are given for middleware structure, a simple logger middleware, and a "superstitious" middleware that modifies actions conditionally. Popular middleware libraries like redux-promise, redux-thunk, and Redux-logger are also mentioned.
Angularjs architecture
This document discusses the architecture of AngularJS applications. It outlines several key components of AngularJS architecture:
1. Configurations define everything needed for the system using a blueprint approach.
2. The routing system acts like a map to help users navigate between different routes, spots, trips, and days.
3. Pages define templates and controllers to determine how each room (page) looks and functions.
4. Directives define templates and controllers for reusable components.
5. Services provide reusable functionality like data access across the application similarly to companies or government agencies.
6. Filters decorate pages by hiding unwanted content to improve visuals.

Tools mentioned include Babel, Browserify, Gulp, and Webpack. Examples provided are a meal planner app using Webpack and one using Browserify.
ReactJS presentation.pptx
React JS is a JavaScript library for building user interfaces. It uses virtual DOM and one-way data binding to render components efficiently. Everything in React is a component - they accept custom inputs called props and control the output display through rendering. Components can manage private state and update due to props or state changes. The lifecycle of a React component involves initialization, updating due to state/prop changes, and unmounting from the DOM. React promotes unidirectional data flow and single source of truth to make views more predictable and easier to debug.

Writing HTML5 Web Apps using Backbone.js and GAE
A walkthrough of how to write a complete HTML5 web app (both front end and back end) using Google App Engine (Python), Backbone.js, Require.js, underscore.js and jQuery.
Rp 6 session 2 naresh bhatia
1) The document discusses how to build modular web applications using the JavaScript frameworks Backbone.js and RequireJS. It advocates separating an application into reusable components using the Model-View-Controller (MVC) pattern and composing the interface from independent views.
2) RequireJS allows code to be split into bite-sized modules and defines dependencies between modules. This supports large-scale application development and avoids dependency issues.
3) The document provides an example of a fictitious stock trading application called Bullsfirst that demonstrates these techniques and emphasizes the importance of architecture for engaging web applications.

MV* presentation frameworks in Javascript: en garde, pret, allez!
HTML5 is the playing area, the strip, Javascript presentation frameworks are the fences and they are fierce and proud. In this presentation we will attend an interesting match between two of the emerging contenders in the MV* family: KnockoutJS and BackboneJS. We'll try to understand how they solve the same issues in modern web software development to better decide which one is suitable in our scenario.
reactJS
This document provides an introduction to React.js, including:
- React is a JavaScript library for building user interfaces and was developed by Facebook. It is the VIEW component in MVC architecture.
- Key features and benefits of React include being fast, modular, scalable, flexible, and popular due to its employability. Large companies like Facebook use React.
- Core concepts of React include JSX, components, unidirectional data flow, and the virtual DOM which improves performance compared to traditional frameworks. Components are reusable pieces that make up the entire application.
Jinal desai .net
The document discusses ASP.NET MVC framework concepts including:
- MVC architecture divides applications into models, views, and controllers. Models manage state, views display UI, and controllers handle user input and choose views.
- Advantages of MVC include clean separation of concerns, testable UI, reuse of views/models, and organized code.
- The Razor view engine renders HTML from dynamic server-side code using a specially designed parser.
- ASP.NET MVC classes are in the System.Web.Mvc namespace which contains controllers, views, and other core classes.
Backbone introdunction
Backbone.js is a JavaScript MVC framework that provides structure to web applications. It includes models to represent and persist data, collections to store and enumerate models, views to manipulate the DOM based on models/collections, and connects it all through a RESTful JSON API. The framework aims to abstract away complexity, decouple UI from data, and avoid callback hell. Examples show how models represent data, collections store models, and views tie them together through the DOM.
React JS Belgium Touch Base - React, Flux, React Native
This document provides an introduction to ReactJS, including:
- ReactJS is a JavaScript library for building user interfaces using components and a virtual DOM. It implements unidirectional data flow.
- Components are used to build up user interfaces and can receive data via props. The virtual DOM allows for efficient updates before rendering to the real DOM.
- Flux is an architecture used with React for unidirectional data flow between actions, stores, and React components.
- React Native allows building native mobile apps using React by rendering natively on each platform rather than with HTML and CSS.
Getting started with React and Redux
React and Redux are JavaScript libraries used to build user interfaces and manage application state. React focuses on building reusable UI components and rendering views based on state changes. Redux helps manage state by using pure reducer functions to update state in a predictable way in response to actions. Together, React and Redux provide a declarative way to build component-based UIs and maintain consistent state across a JavaScript application.

Cosa hanno in comune un mattoncino Lego e la backdoor XZ?
BackboneJS + ReactJS
- 2. Library vs Framework ?? A library performs specific, well-defined operations. A framework is a collection of patterns and libraries to help with building an application. Backbone.js (Model/Controller) - Framework React.js (View) - Library “Frameworks skip Somework”
- 3. BackboneJS Frontend uber-light MVC framework,with RESTful support & more flexible. Pros can be easily integrated into an existing project & adding structure to Javascript... My application is going to do a lot of heavy DOM manipulations & handle large chunk of data. Cons Learning curve not as simple as other MVC External dependencies like Jquery, Underscore.js Non RESTful API backend Nested backbone View difficult to maintain, every collection changes re-render all the views.
- 4. Backbone Models Model encapsulate business logic and data var Todo = Backbone.Model.extend({ defaults: { title: 'backbone_title', }, initialize: function(){ console.log('This model has been initialized.'); }, setTitle: function(newTitle){ this.set({ title: newTitle }); } }); var myTodo = new Todo(); myTodo.setTitle('Backbone Hello world.');
- 5. Backbone View Views are responsible for listening to DOM element's events & updating the DOM elements. View templates -- underscore.js handlebar.js var AppView = Backbone.View.extend({ // el - stands for element. Every view has a element associate in with HTML content will be rendered. el: '#container', initialize: function(){ this.render(); }, render: function(){ this.$el.html("Hello World"); } });
- 6. ReactJS React is a UI library to facilitate the creation of interactive, stateful & reusable UI components. Building large applications with data that changes over time. It's just a View of M'V'C framework. Virtual DOM (USP). React has only “Components” that will just re-render. Javascript + HTML = JSX JSX - Allows us to write HTML like syntax which gets transformed to lightweight JavaScript objects. Render in Server via node.js
- 7. Components & LifeCycle Component = view/HTML + controller/JS React.createClass({ }) The way in which you create a new component. State -- Internal data,can change Prop -- External data,can't change UpdateCycle Component LifeCycle React.createClass() componentWillUnmount() getInitialState() componentDidMount() componentWillMount() Render() Render() componentWillUpdate() componentDidUpdate()
- 8. Virtual DOM when data has changed ?? which DOM element(s) to be updated?? Angular “Digest cycle” mechanism On every update in the State React's diffing algorithm DOM Structure Patch boolean shouldComponentUpdate()
- 9. Architecture Traditional MVC Difficult to organise the code Good to use Asynchronous Module Definition (AMD) like require.js,browserify,gulp Flux Architecture Dispatcher acts as traffic controller. One-way data flow. dispatcheraction store view View model model model model view View View controller
- 10. Challenges Code maintenance (JS + HTML) No two way data-binding No separate Templates Converting JSX to JS (Babel) ReactJS Gotchas Re-initialise datatables Alerts account landing page DEMO
