Isomorphic JavaScript Web Development

By: Tomas Alabes, Konstantin Tarkus

Overview of this book

<p>The latest trend in web development, Isomorphic JavaScript, allows developers to overcome some of the shortcomings of single-page applications by running the same code on the server as well as on the client. Leading this trend is React, which, when coupled with Node, allows developers to build JavaScript apps that are much faster and more SEO-friendly than single-page applications.</p> <p>This book begins by showing you how to develop frontend components in React. It will then show you how to bind these components to back-end web services that leverage the power of Node. You'll see how web services can be used with React code to offload and maintain the application logic. By the end of this book, you will be able to save a significant amount of development time by learning to combine React and Node to code fast, scalable apps in pure JavaScript.</p>

Preface

Stateful versus stateless React components


The majority of UI elements of a web app tends to be stateless React components, which will be rendered the same way given the same input parameters. This is based on a well-known idea of pure functions.

The best way to write such components is by using simple functions accepting props, as the following example demonstrates:

function Checkbox({ name, label, ...other }) { 
  return ( 
    <div className="field" {...other}> 
      <input className="input" type="checkbox" name={name} />
      <label className="label">{label}</label> 
    </div> 
  ); 
}

Note

If this list of function arguments looks foreign to you, you may want to read about destructing assignment on MDN:https://developer.mozilla.org/en/docs/Web/JavaScript/Reference/Operators/Destructuring_assignmentfunction ({ name }) { console.log(name); } vsfunction (props) { console.log(props.name); }

It is considered a good practice to always validate input parameters of...
