Mastering JavaScript Single Page Application Development

Overview of this book

Single-page web applications—or SPAs, as they are commonly referred to—are quickly becoming the de facto standard for web app development. The fact that a major part of the app runs inside a single web page makes it very interesting and appealing. Also, the accelerated growth of browser capabilities is pushing us closer to the day when all apps will run entirely in the browser. This book will take your JavaScript development skills to the next level by teaching you to create a single-page application within a full-stack JavaScript environment. Using only JavaScript, you can go from being a front-end developer to a full-stack application developer with relative ease. You will learn to cross the boundary from front-end development to server-side development through the use of JavaScript on both ends. Use your existing knowledge of JavaScript by learning to manage a JSON document data store with MongoDB, writing a JavaScript powered REST API with Node.js and Express, and designing a front-end powered by AngularJS. This book will teach you to leverage the MEAN stack to do everything from document database design, routing REST web API requests, data-binding within views, and adding authentication and security to building a full-fledged, complex, single-page web application. In addition to building a full-stack JavaScript app, you will learn to test it with JavaScript-powered testing tools such as Mocha, Karma, and Jasmine. Finally, you will learn about deployment and scaling so that you can launch your own apps into the real world.

Pure.js


Pure.js is a JavaScript templating engine that takes the concept of logic-less templates to an even greater extreme than Mustache and Handlebars do. Pure.js uses no special template expression syntax that has to be interpolated before rendering. Instead, it uses only pure HTML tags and CSS selectors, combined with JSON data, to render values in the DOM. In this way, Pure.js uses entirely logic-less views because there is no template markup in which to include any logic.

Markup

Using plain HTML, a simple Pure.js template can be constructed like this:

<p class="my-template"> 
    Hello, my name is <span></span>. 
</p> 

The empty <span> element is where you might add data for a particular template, but you can use any HTML tag.

var data = { 
    name: 'Udis Petroyka' 
}; 
 
var directive = { 
    'span': 'name' 
}; 

In this example, we provide the data for the template in the data variable, and then provide...
