Overview of this book

The reader will learn how to use React and its component-based architecture in order to develop modern user interfaces. A new holistic way of thinking about UI development will establish throughout this book and the reader will discover the power of React components with many examples. After reading the book and following the example application, the reader has built a small to a mid-size application with React using a component based UI architecture. The book will take the reader through a journey to discover the benefits of component-based user interfaces over the classical MVC architecture. Throughout the book, the reader will develop a wide range of components and then bring them together to build a component-based UI. By the end of this book, readers would have learned several techniques to build powerful components and how the component-based development is beneficial over regular web development.

Animating new components


At the moment, new pages are just appearing. There's no subtle animation to ease them in. Let's change that!

We will use a new React component for this, and we can find it in the add-ons build of React. Go back to the React scripts you downloaded in the first chapter and replace all references to react.js with react-with-addons.js.

This gives us access to a new component called CSSTransitionGroup:

render() {
    var itemStyle = this.props.itemStyle || {
        "minHeight": "40px",
        "lineHeight": "40px",
        "fontSize": "18px",
        "fontFamily": "Helvetica"
    };

    return <div>
        <div>
            <button
                onClick={this.onInsert}>
                create new page
            </button>
        </div>
        <ol>
            <React.addons.CSSTransitionGroup
                transitionName="page"
                transitionEnterTimeout={150}
                transitionLeaveTimeout={150}>
  ...
