A quick introduction to Facebook's react.js framework. This deck covers react components, flux architecture, and how to build an isomorphic application.
This document discusses how to develop applications using the Staged Event Driven Architecture (SEDA) model with Akka. It describes how to decompose an application into stages connected by message queues, and how Akka actors can be used to implement the individual stages. Backpressure is discussed as important to prevent out of memory errors from message backups. Various Akka configuration options are presented for dispatchers, mailboxes, routing, and fault tolerance.
This document discusses introducing Flux and React in practice. It provides an overview of Flux as an architecture with one directional data flow. React is described as a library for creating views with components. The document then discusses how Flux and React work together, with data flowing from the store to components through a dispatcher. It provides examples of using Flux and React to build a music player app and mobile store app.
React is a JavaScript library for building user interfaces that uses a virtual DOM for improved performance. It uses a one-way data flow and declarative components. The virtual DOM allows React to efficiently update the real DOM by only making necessary changes. Components in React encapsulate elements and can have state and props. JSX is recommended for writing React components and compiles to plain JavaScript.
The document summarizes Kiran Abburi's presentation on React. It covers:
1. The agenda includes basics of React, composition, data flow, JSX, React APIs, and building a todo app.
2. React is a JavaScript library for building user interfaces and uses a component-based approach to build encapsulated pieces.
3. Data in React flows in a uni-directional way through properties (props) and state, where props are passed from parent to child components and state is internal to a component.
React is a JavaScript library for building user interfaces and applications. It uses components rather than templates, implements a one-way data flow downwards and re-renders components on data changes rather than mutating them directly. The virtual DOM in React allows for simple and fast re-rendering. Key aspects of React include components, one-way data flow, re-rendering without mutation, the virtual DOM, JSX syntax and React Native for building mobile apps. Flux is an architecture pattern used for state management in React, implementing unidirectional data flow through actions, a dispatcher, stores and views.
This document discusses using React and Redux to build an app for managing conferences. It describes building a conference scheduling app with React components to define the UI and Redux to manage shared state. Redux uses a central store with actions and reducers to update the state, which is then mapped to props and passed to React components. Key aspects covered include creating React components, action creators, reducers, connecting React to Redux with the connect function, and rendering the app with a Provider component wrapping the connected components.

Introduce Flux & react in practices (KKBOX)Hsuan Fu Lien
Flux is an application architecture pattern for building user interfaces that uses unidirectional data flow. React is a view library that handles the visual DOM and component lifecycle. Flux uses a dispatcher to facilitate one-way data flow from the actions to stores to views. Stores hold the application state and trigger changes that cause React components to re-render. Together, Flux architecture and React components allow building large web applications in a predictable and performant way.
This document discusses server-side rendering with Redux. It explains the benefits of universal/isomorphic rendering like improved SEO and perceived performance. It covers rendering the initial HTML on the server, handling async logic, and using the redux-universal library to synchronize rendering and async actions on client and server.
React js is a JavaScript library created by Facebook in 2013 for building user interfaces and rendering UI components. It uses a virtual DOM to efficiently update the real DOM and allow building of reusable UI components. React code can be written directly in HTML or using JSX syntax and by setting up a React app with Node.js and NPM. Components are the building blocks of React and can be class or function based. Props and state allow passing data to components and re-rendering components on state changes.
This is the first half of a presentation I gave at Squares Conference 2015 where I provided a brief introduction to React JS, then did live coding for 20 minutes to show more of the specifics of usage. Your milage may vary as the live code part was where the bulk of the teaching happened!
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.
This document discusses React component lifecycle methods and the different phases a component goes through: initialization, mounting, updating, and unmounting. It provides details on the purpose and usage of each lifecycle method, including the constructor, componentWillMount, render, componentDidMount, componentWillReceiveProps, shouldComponentUpdate, componentWillUpdate, componentDidUpdate, and componentWillUnmount. The lifecycle methods allow performing actions at specific stages of the component's existence, such as initializing state, integrating APIs, updating based on new props or state, and cleaning up.

Slides from talk given Jan 2016 at the LondonReact meetup at Facebook: http://www.meetup.com/London-React-User-Group/events/227112505/
This document discusses techniques for scaling React and Redux applications at IOOF, including:
1. How they produce a consistent and theme-able UI and partition the Redux store to allow fully decoupled development of micro frontends.
2. How micro frontends are encapsulated pieces of the front end defined by a domain concept that can run independently with limited setup and are published as npm libraries exporting a top-level component.
3. How they avoid "action cross talk" between micro frontends by ensuring actions only update their own state, and how micro frontends are ignorant of state structure outside their own using techniques like action namespacing, a state traversal map, and Redux subspaces

React is a JavaScript library for building user interfaces using reusable components. The core concepts of React include JSX, components, unidirectional data flow, and the virtual DOM. Everything in React is components that can interact with each other and maintain state. Data flows unidirectionally via state and props from parent to child components. The virtual DOM selectively re-renders the UI when the state changes, improving performance. Redux follows a similar unidirectional data flow architecture, with data moving from actions to reducers to the store.
This document summarizes a presentation about building modern web parts with React and Redux. It discusses why Microsoft is using React in Office 365 applications and how React combined with Redux helps build single page applications. It provides an overview of React components and state management. It also summarizes the basic principles of Redux, including how data is contained in the application and views are contained separately. The document shares code for an example FAQ web part built with React and Redux and diagrams the overall application structure and data flow.

React gsg presentation with ryan jung & elias malikLama K Banna
React is a client-side JavaScript library for building user interfaces that is made and open-sourced by Facebook. It uses a virtual DOM for fast rendering and reusable components to build up the UI. Components can have their own state that causes re-rendering when updated. Events are handled through callbacks. JSX allows writing HTML-like code mixed with JavaScript.
Managing state across complex apps with many interacting components can be challenging. Flux and Redux address this with a single source of truth store and reducer functions that update state immutably in response to actions. Side effects like API calls require middleware like thunks, sagas, or API-specific middleware to isolate impure logic from pure reducers.
This document provides an overview of several core technologies used in React applications, including React, Flux, Node.js, Browserify, and Gulp. It discusses that React is a JavaScript library for building user interfaces and rendering UI as HTML. It uses virtual DOM for efficient updates. Flux is an architecture for uni-directional data flow. Node.js is used for server-side JavaScript with npm. Browserify allows using Node modules in the browser. Gulp is a build system for tasks like bundling files.

The document concludes with exercises for creating basic React and React Native apps.
Webcamp Zagreb, 2016
React is a great view layer, but what about the rest of the app structure?
React is a great view layer, but if you want to create something more than a simple TODO app, you’ll need some other parts. First of, you’ll need a data structure and a way to handle the changes in it. Although the most simple way to do it could be to take parts of a framework you’re used to (e.g. Backbone Collections/Models), there is something better out there. First, there was the Flux architecture, made by Facebook itself - it forced us to change and consume our data in a certain way in order to prevent developers from shooting themselves in the foot. Then there was Redux - a state container that preaches immutability and time travel. While Redux is great, and enables us great things like hot module reloading, it is also very strict and introduces a lot of boilerplate code. MobX, on the other side, has almost no boilerplate code, can be strict when/if you want it to be, and gives you a nice performance boost for free.

12. Flux
Available app-wide. We use Fluxxor.
• Actions — things to do; api calls for example
• Stores — one source of truth; all app data
• and constants (aka dispatcher)

20. Isomorphism
Client side rendering
• Javascript app running
in browser
• Slow initial load :/
• New pages are quick
— just fetch json data
Server side rendering
• Generate page on
server
• Quick initial page load
• SEO works
• HTTP request for each
new page :/
Why not have both?
We use react-router for client-side & server-side routing.
21. Isomorphism
On the server, pass
everything to the react
app.
React.renderToString()
— view/html only; no
js/ui.
