React is an open source JavaScript library for building user interfaces. It was created by Jordan Walke at Facebook in 2011 and is now maintained by Facebook, Instagram, and a community of developers. Major companies using React include Facebook, Instagram, Netflix, Khan Academy, and PayPal. React uses a virtual DOM for faster rendering and makes components that manage their own state. It uses JSX syntax and a one-way data flow that is declarative and composable.
Experiences building apps with React Native @UtrechtJS May 2016Adrian Philipp
React Native is all about combining great user experience on native platforms with the developer experience of React on the web. Since it’s start one year ago, React Native continuously enjoys a tremendous traction. In 2015 React got popular, 2016 will be the year of React Native. I followed the development since the start and now I’m busy building my third React Native app. During my talk I like to introduce the library, show useful tooling and give practical advice for building React Native apps.

Building a PWA with Ionic, Angular, and Spring Boot - GeeCON 2017Matt Raible
In this session, I show how to build a Progressive Web App (PWA) using Ionic, Angular, and Spring Boot. PWAs are being hyped as the next big thing in mobile development. This talk will cut through the hype and get down to the nitty-gritty. Are they really better than native applications? Can you develop PWAs and easily target mobile and desktop with the same application?

Una charla sobre React Native que di el 23 de Marzo 2017 en el meetup ValenciaJS: https://www.meetup.com/es-ES/ValenciaJS/events/238249872/
En 2016 desarrollé durante seis meses una aplicación para React Native. En esta charla compartí todo lo que he aprendido sobre este framework, y cómo os puede servir para crear una app nativa para iOS y Android al mismo tiempo de manera rápida y ágil.
Hablé sobre la parte positiva, y las cosas que aceleraron nuestro proceso de desarrollo, pero también sobre algunos inconvenientes que hay que tener en cuenta. Se trata sobre todo de problemas muy específicos de cada plataforma, poner en marcha un flujo de integración continua y facilitar un proceso sencillo de testar la app con los usuarios.
React Native es una buena solución que está muy de moda pero esto no significa que hay que usarlo sin analizar bien las necesidades de tu proyecto. Presenté brevemente una alternativa (Ionic 2) y conté que ventajas tiene en comparación con React Native desde mi punto de vista.

Automating Hybrid Applications with AppiumSauce Labs
When creating a mobile application, organisations have a few options to choose from; mobile web, native or a hybrid application. Where web apps are just websites that can be accessed on the internet via a mobile browser like Chrome or Safari, native apps are applications that are developed for a specific platform such as Android or iOS. Hybrid apps are different because they possess elements from native apps and web apps.
When automating web applications, Selenium commands are used. Nine out of ten times the same automation script can be used for mobile web applications as our desktop web applications. With native apps however, we need to look deeper into the differences between Android and iOS apps before we can use Appium commands.
But how should you automate hybrid apps, can or do you need to choose one of the two automation strategies or is there also a hybrid approach for automating hybrid apps?
That’s what we are going to talk about during this webinar. We will be looking into how to detect a hybrid application for Android and iOS, the do’s and the don’ts when it comes to automating a hybrid application and we will provide you with tips and tricks on how to make this work for both Android and iOS.
By the end of this webinar, you’ll be able to create your own Appium scripts to automate Android and iOS hybrid mobile applications.
Key Takeaways:
- Understand what a hybrid mobile application is
- How to detect a hybrid mobile application
- Learn how iOS and Android handle hybrid mobile applications
- Learn how to automate hybrid mobile applications

Listen to the keynote address and hear about the latest developments from Rachana Ananthakrishnan and Ian Foster who review the updates to the Globus Platform and Service, and the relevance of Globus to the scientific community as an automation platform to accelerate scientific discovery.
Providing Globus Services to Users of JASMIN for Environmental Data AnalysisGlobus
JASMIN is the UK’s high-performance data analysis platform for environmental science, operated by STFC on behalf of the UK Natural Environment Research Council (NERC). In addition to its role in hosting the CEDA Archive (NERC’s long-term repository for climate, atmospheric science & Earth observation data in the UK), JASMIN provides a collaborative platform to a community of around 2,000 scientists in the UK and beyond, providing nearly 400 environmental science projects with working space, compute resources and tools to facilitate their work. High-performance data transfer into and out of JASMIN has always been a key feature, with many scientists bringing model outputs from supercomputers elsewhere in the UK, to analyse against observational or other model data in the CEDA Archive. A growing number of JASMIN users are now realising the benefits of using the Globus service to provide reliable and efficient data movement and other tasks in this and other contexts. Further use cases involve long-distance (intercontinental) transfers to and from JASMIN, and collecting results from a mobile atmospheric radar system, pushing data to JASMIN via a lightweight Globus deployment. We provide details of how Globus fits into our current infrastructure, our experience of the recent migration to GCSv5.4, and of our interest in developing use of the wider ecosystem of Globus services for the benefit of our user community.
We describe the deployment and use of Globus Compute for remote computation. This content is aimed at researchers who wish to compute on remote resources using a unified programming interface, as well as system administrators who will deploy and operate Globus Compute services on their research computing infrastructure.

First Steps with Globus Compute Multi-User EndpointsGlobus
In this presentation we will share our experiences around getting started with the Globus Compute multi-user endpoint. Working with the Pharmacology group at the University of Auckland, we have previously written an application using Globus Compute that can offload computationally expensive steps in the researcher's workflows, which they wish to manage from their familiar Windows environments, onto the NeSI (New Zealand eScience Infrastructure) cluster. Some of the challenges we have encountered were that each researcher had to set up and manage their own single-user globus compute endpoint and that the workloads had varying resource requirements (CPUs, memory and wall time) between different runs. We hope that the multi-user endpoint will help to address these challenges and share an update on our progress here.

9. JSX
Supports xml-like syntax inline in JavaScript
Each element is transformed into a Javascript function call
• <Hello /> => Hello(null)
• <div /> => React.DOM.div(null)
10. Virtual DOM
Problem:
• DOM manipulation is expensive
• Touching DOM is hard to test
• Re-render all parts of DOM make your app slowly
11. Virtual DOM
Solution:
When the component’s state is changed, React
• Use different algorithm with the browser DOM tree to
identify the changes
• Instead of creating new object, React just identify what
change is took place and once identify update that state
• Render the subtree of DOM elements into the rendering of
the DOM
14. Prop / State
Prop:
• Used to pass parameter from parent to children
• PropTypes used to validate properties
• getDefaultProps
State:
• Used to manage state inside component
• getInitialState
• setState
16. Mixins / Statics
Mixins:
• Different components may share some common functionality
• Several mixins can be defined
• Methods defined on mixins run in the order mixins were
listed
Statics:
• Like .Net / Java static method
• Define static methods in statics block of component
17. Events
componentWillMount: Invoked once before the initial render
componentDidMount: Invoked once, only on the client
componentWillReceiveProps: Invoked when a component is receiving new props
shouldComponentUpdate: Invoked before rendering when new props or state are
being received
componentWillUpdate: Invoked immediately before rendering when new props or
state are being received
componentDidUpdate: Invoked immediately after the component's updates are
flushed to the DOM
componentWillUnmount: Invoked immediately before a component is
unmounted from the DOM
21. Flux
Action: Helper method that facilitate passing data
to the Dispatcher
Dispatcher: Receive action and broadcast
payload to registered callback
Store: Containers for application state & logic that
have callbacks registered to the dispatcher
View: State from Stores and pass it down via props
to child components
23. Redux
• Single source of truth
• State is read-only
• Mutations are written
as pure functions
(reducers)
24. Redux
• Important difference to Flux: no dispatching inside the action
• There is no Dispatcher at all; pure functions do not need to
be managed, they need to be composed
• Mutations are written as pure functions
In 2010, Facebook released an extension for PHP called XHP.
XHP help to decrease XSS attack and make front-end much both readable and understand.
There was a distinct problem with XHP: dynamic webapplications require many roundtrips to the server.
XHP did not solve this problem.
Jordan Walke negotiated with his manager to take XHP into the browser using JavaScript and was granted six months to try it
It was first deployed on Facebook's newsfeed in 2011 and later on Instagram.com in 2012.
It was open-sourced at JSConf US in May 2013.
React Native, which enables native iOS and Android development with React, was announced at Facebook's React.js Conf in February 2015 and open-sourced in March 2015.

Facebook has been working to help build a cross-platform development platform called React.
Earlier this year, Facebook announced React Native, a learn-once, run-everywhere platform to take JavaScript and build native-like apps for iOS and Android.
Run on server-side on NodeJs.
Discontinuing IE8 support in React DOM, January 2016.
Data flow from the parent to the children component by the state and the props
Only one parent is responsible to update the states and passing the value to the children components via props
setState is used to update/refresh the UI when the state change and the value can be pass to the children component by the this.props
Event flow up, data flow down
Transform JSX to pure JavaScript immediately before execution
Convenient for the developer
Significant performance penalty
Can’t be minified
Use Babel.js / JSXTransformer.js deprecated

componentWillMount: Good place to make connection to your db service
componentDidMount: It is good place for you to make AJAX request to fetch data for first used.
componentWillReceiveProps: Use this method as a way to react to a prop change before render() is called by updating the state with setState.
componentWillUnmount: Perform any necessary cleanup in this method(Ex: invalidating timers, clear up DOM elements were created at componentDidMount)
Flux is an architecture that Facebook uses internally when working with React. It isnot a framework or a library. It is simply a new kind of architecture that complements React and the concept of Unidirectional Data Flow.
Dispatcher is the central hub that manages all data flow, It is a registry of callbacks into the stores
Action typically triggered by the View, contain information about change made to the application
Store contain application state and logic, reacts to specific action.
View has list of stores which provide data for, trigger action with the state changes
After you use Flux the first time, writing React without Flux feels like DOM traversal without jQuery. You can absolutely do it, but it feels less elegant and structured.
Flummox, Alt, Fluxxor are libraries implement Flux.

Actions are payloads of information that send data from your application to your store
Reducer is a pure function that takes the previous state and an action, and returns the next state.
Store is the object that brings them together. (holds application state)
You call store.dispatch(action)
The Redux store calls the reducer function you gave it
The root reducer may combine the output of multiple reducers into a single state tree
The Redux store saves the complete state tree returned by the root reducer
