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.

Creating the services

Let's first build the services before building the image storage server and monolithic core.

We will build the database service first, as it only depends on the MongoDB server, which is already running. The upload service and monolithic core depend on it, therefore it needs to be built before these.

Database service

The database service will provide actions to add coupons, list verified coupons, list unverified coupons, verify a coupon, and delete a coupon. These actions will be used by the upload service and monolithic core.

Open the Initial/database-service directory. Inside the directory, you will find a package.json file and an app.js file. The app.js file is where you will write the code, and package.json lists the dependencies for the database service. The database service is dependent on the seneca and seneca-mongo-store plugins. Run the npm install command inside Initial/database-service to install the dependencies locally.

Here is the code to import the seneca...
