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.
In this presentation, Prashant Sharma of Valuebound has talked about ReactJS - a JavaScript library for building user interfaces. Check out the agendas to know what is there for you.

Plain React detects changes by re-rendering your whole UI into a virtual DOM and then comparing it to the old version. Whatever changed, gets patched to the real DOM.
React (or React Js) is a declarative, component-based JS library to build SPA(single page applications) which was created by Jordan Walke, a software engineer at Facebook. It is flexible and can be used in a variety of projects.

The speed of innovation in the JavaScript world is insane: in a few months libraries, frameworks and tools can go from little experiments to something being used by millions of people. In this talk the attention will be focused on React, a library made by Facebook, and on the state of art of the state and data management (Redux/Mobx), testing (Enzyme), modules and syntax (Webpack/Babel) and style (CSS Modules).
Outline:
- React (Main concepts, Props, State, Component Lifecycles, Mixins, ES6 Syntax, Stateless Functional Components, High Order Components, Routing)
- State Management (Redux, Mobx)
- Testing (Enzyme)
- Webpack
- CSS Modules
Presentations includes following topics :-
Introduction of ReactJS.
Component workflow.
State management and useful life-cycles.
React hooks.
Server Side Rendering.
Starting with Spring MVC 2.5, Annotation-Based Controllers became the preferred model for development (the Interface-based Controller hierarchy will be deprecated in Spring 3). This session will teach developers familiar with the old model how to use the new Annotation-based Controllers. This will also provide the basis for writing JSR 286 portlets using Spring 3.

Climate Science Flows: Enabling Petabyte-Scale Climate Analysis with the Eart...Globus
The Earth System Grid Federation (ESGF) is a global network of data servers that archives and distributes the planet’s largest collection of Earth system model output for thousands of climate and environmental scientists worldwide. Many of these petabyte-scale data archives are located in proximity to large high-performance computing (HPC) or cloud computing resources, but the primary workflow for data users consists of transferring data, and applying computations on a different system. As a part of the ESGF 2.0 US project (funded by the United States Department of Energy Office of Science), we developed pre-defined data workflows, which can be run on-demand, capable of applying many data reduction and data analysis to the large ESGF data archives, transferring only the resultant analysis (ex. visualizations, smaller data files). In this talk, we will showcase a few of these workflows, highlighting how Globus Flows can be used for petabyte-scale climate analysis.
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.

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.

Session 3
Building a simple todo app with react
6. WHAT IS REACT ?
A javascript library for building user interfaces
V in MVC
Simple & Declarative
10. REACT COMPONENTS
React is all about building components
We build small reusable components
Compose components to build larger components
Page
Header
Logo
Menu
Content
SideBar
MainBody
Footer
13. DATA FLOW
Uni-directional data flow
Two types of data: props & state
props are used to pass data and configuration to children
state is the application state of component
26. render
This method is required in all components
render() function should be pure
Should not modify component state
var Todo = React.createClass({
render: function () {
return <div></div>
}
});
27. getInitialState
Invoked once before the component is mounted.
The return value will be used as the initial value of
this.state
var Todo = React.createClass({
getInitialState: function () {
return { todos: [] }
},
render: function () {
return <div></div>
}
});
28. getDefaultProps
provides default values for the props that not specified by
the parent component
var Person = React.createClass({
getDefaultProps: function () {
return { name: anonymous }
},
render: function () {
return <h1>{this.props.name}</h1>
}
});
<Person name='kiran' />
<Person />
29. mixins
to share behavior among multiple components
var FormMixin = {
submitHandler: function () {
// submit form
},
changeHandler: function () {
// handle input changes
}
}
var Form1 = React.createClass({
mixins: [FormMixin],
render: function () {
return <form onSubmit={this.submitHandler}> </form>
}
})
30. COMPONENT LIFE CYCLE
hooks to execute code at at specific points in a
component's lifecycle
Most commonly used
componentWillMount
componentDidMount
componentWillUpdate
componentDidUpdate
componentWillUnmount
31. componentWillMount
Invoked once immediately before the initial rendering
occurs
var Component = React.createClass({
componentWillMount: function () {
// code to run before rendering
},
render: function () {
return <div></div>
}
})
32. componentDidMount
Invoked once immediately after the initial rendering
occurs
integrate with other JavaScript frameworks
send AJAX requests
var Component = React.createClass({
componentDidMount: function () {
// code
},
render: function () {
return <div></div>
}
})
33. componentWillUpdate
Invoked immediately before rendering when new props or
state are being received.
This method is not called for the initial render.
var Component = React.createClass({
componentWillUpdate: function () {
// code
},
render: function () {
return <div></div>
}
})
34. componentDidUpdate
Invoked immediately after the component's updates are
flushed to the DOM
var Component = React.createClass({
componentDidUpdate: function () {
// code
},
render: function () {
return <div></div>
}
})
35. componentWillUnmount
Invoked immediately before a component is unmounted
from the DOM.
Cleanup like unregistering event listeners
var Component = React.createClass({
componentWillUnmount: function () {
// code
},
render: function () {
return <div></div>
}
})
