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.

Other differences in Handlebars from Mustache templates


Many of the features in Handlebars.js that differentiate it from Mustache.js are designed to make the templates render more quickly in a browser. One of the main features in Handlebars that allows this is the ability to precompile templates, as we covered in Chapter 2, Model-View-Whatever.

Precompiling templates

Precompiling the templates converts them to the JavaScript functions that are normally compiled in an application before rendering with other templating engines. Using this feature increases the speed of an application by skipping that step, and it additionally reduces the load on the browser for the application because the JavaScript compiler does not need to be included in the frontend asset payload.

No alternative delimiters

The creators of Handlebars also decided that the ability to set alternative delimiters within a template is not necessary. This further reduces the asset payload for an application if you are not precompiling...
