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.

Scaling the SPA

I want to conclude with a few ideas about scaling the application. Scaling an application is a bit of a black art, but you do want to be prepared should you build out an application and it gets very popular very fast.

One of the really nice things about using PaaS tools is that they simplify scaling significantly.

Scaling the database

There are a number of options and considerations for scaling the database. You can see this just by looking at the different packages offered by MongoLab. MongoDB itself supports sharding and replication, as it was built for scaling.

Concerns about scaling include the size of the database - how much storage, and performance - usually a factor of RAM or using dedicated clusters.

MongoLab and other providers offer numerous combinations of high-storage and high-performance plans along with several steps, allowing you to incrementally increase your scaling without missing a beat, or installing or configuring a new hardware.
