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.

Using event emitters

Until now, our components have communicated with the backend through method calls. That's OK for tiny applications, but when things start to scale, we will forget to make some of those method calls.

Look at onUpdate, for instance:

onUpdate(id, field, value) {
    this.props.backend.update(id, field, value);

    this.setState({
        "pages": this.props.backend.getAll()
    });
}

Every time we change the state of a page, we have to fetch an updated list of pages from the backend. What if multiple components send updates to the backend? How will our PageAdmin component know when to fetch a new list of pages?

We can turn to event-based architecture to solve this problem. We've already encountered and used events! Recollect what we did when we created the page edit form. There, we connected to input events so we could update pages when input values changed.

This kind of architecture moves us closer to a unidirectional flow of data. We can imagine our entire...
