React is an open-source JavaScript library from Facebook used for building HTML5 web applications. In this training course, you learn how to develop a complete application by building high-performance User Interfaces (UIs) with JSX components targeting a virtual DOM, and creating Flux applications, which provide complementary architectural patterns to construct client-side application functionality.

You Will Learn How To

  • Create an isomorphic web application using Facebook React and Flux
  • Compose a UI using React JavaScript and JSX components
  • Integrate React forms with Ajax and back-end REST services
  • Apply the Flux application pattern (dispatcher, stores, and actions)
  • Exploit React animation components with CSS3 transitions

Important Course Information

  • Requirements

    • Experience developing web pages with JavaScript, HTML, and CSS at the level of:

Course Outline

Parameterizing components

  • Disambiguating component properties and state
  • Inserting properties into rendered output with this.props
  • Passing property values using JSX { } expressions
  • Initializing default values with getDefaultProps()

Manipulating component state

  • Setting starting state values with getInitialState()
  • Reading application data with this.state
  • Mutating data with this.setState()
  • Harnessing React autobinding and event aggregation

Integrating into the component life cycle

  • Attaching and detaching logic and event handlers in componentDidMount and componentWillUnmount
  • Enhancing performance with componentShouldUpdate
  • Responding to changes with componentWillReceiveProps
  • Developing React Forms

Manipulating form input components

  • Working with interactive properties
  • value
  • defaultValue
  • checked
  • selected
  • Capturing form component updates with onChange
  • Comparing controlled and uncontrolled components

Simulating two-way binding

  • Applying the onChange / setState() convention
  • Employing the LinkedStateMixin
  • Passing ReactLink objects through the props hierarchy

Connecting React to REST services

  • Making Ajax calls from React
  • Mapping CRUD access to REST actions
  • GET
  • POST
  • PUT
  • Creating Flux Applications

Modeling client-side data interactivity

  • Identifying Flux participants
  • Actions
  • Dispatcher
  • Stores
  • Views
  • Harnessing unidirectional data flow
  • Comparing Flux to Model View Controller, Redux and Relay

Coding a Flux application

  • Extending the Facebook Dispatcher
  • Utilizing Node.js EventEmitter with custom stores
  • Integrating REST access with Flux action creators

Integrating routing into Flux

  • Exploiting the react-router for semantic URLs
  • Mapping URL paths and parameters to components
  • Analyzing React Applications

Developer tools

  • Inspecting React components with browser extensions
  • Identifying and debugging rendering errors

Unit testing

  • Running tests with Jest
  • Simulating event dispatch with ReactTestUtils.Simulate

Performance testing

  • Establishing a baseline
  • Profiling React execution with Perf.start() and stop()
  • Optimizing component reconciliation with key
  • Animating React Applications
  • Including the react-css-transition-group add-on
  • Employing the ReactCSSTransitionGroup component
  • Writing CSS transitions and animations
