In this chapter, we have learned the new dynamic web application development. It has changed completely over the years. The web application frontend is completely developed in pure HTML and JavaScript instead of using any server side technologies like JSP, servlets, ASP, and so on. UI app development with JavaScript now has its own development environment like npm, bower, and so on. We have explored the AngularJS framework to develop our web app. It made things easier by providing inbuilt features and support to bootstrap and the $http service that deals with the AJAX calls.

I hope you have grasped the UI development overview and the way modern applications are developed and integrated with server side microservices. In the next chapter, we will learn the best practices and common principals of microservice design. The chapter will provide details about microservices development using industry practices and examples. It will also contain examples of where microservices implementation goes wrong and how you can avoid such problems.
