Modern JavaScript Applications

By: Narayan Prusty

Overview of this book

Over the years, JavaScript has become vital to the development of a wide range of applications with different architectures. But JS moves lightning fast, and it’s easy to fall behind. Modern JavaScript Applications is designed to get you exploring the latest features of JavaScript and how they can be applied to develop high-quality applications with different architectures. Begin by creating a single page application that builds on the innovative MVC approach using AngularJS, then move forward to develop an enterprise-level application with the microservices architecture using Node to build web services. After that, shift your focus to network programming concepts as you build a real-time web application with websockets. Learn to build responsive, declarative UIs with React and Bootstrap, and see how the performance of web applications can be enhanced using Functional Reactive Programming (FRP). Along the way, explore how the power of JavaScript can be increased multi-fold with high performance techniques. By the end of the book, you’ll be a skilled JavaScript developer with a solid knowledge of the latest JavaScript techniques, tools, and architecture to build modern web apps.

Architecture of our site


Our server-side application will be composed of a monolithic core, three services, MongoDB server, and image storage server.

The monolithic core will serve pages to the site visitors and administrators.

The three services are database service, URL configuration service, and upload service. The following is what each of these services do:

  • Database service: Adding, retrieving, updating, and deleting coupons in MongoDB is done through database service. The monolithic core retrieves coupons from MongoDB through database service, and upload service stores coupons through database service.

  • Upload service: When a user submits a coupon, the HTML form is submitted to the upload service. The upload service then sends the image to the image storage server and adds metadata about the coupon to the database using the database service. We moved these operations to a different service, because if we are resizing and converting the uploaded image, then it will consume more memory...
