Overview of this book

<p>If you have been burnt by unreliable JavaScript frameworks before, you will be amazed by the maturity of the Angular platform. Angular enables you to build fast, efficient, and real-world web apps. In this Learning Path, you'll learn Angular and to deliver high-quality and production-grade Angular apps from design to deployment.</p> <p>You will begin by creating a simple fitness app, using the building blocks of Angular, and make your final app, Personal Trainer, by morphing the workout app into a full-fledged personal workout builder and runner with an advanced directive building - the most fundamental and powerful feature of Angular.</p> <p>You will learn the different ways of architecting Angular applications using RxJS, and some of the patterns that are involved in it. Later you’ll be introduced to the router-first architecture, a seven-step approach to designing and developing mid-to-large line-of-business apps, along with popular recipes. By the end of this book, you will be familiar with the scope of web development using Angular, Swagger, and Docker, learning patterns and practices to be successful as an individual developer on the web or as a team in the Enterprise.</p> <p>This Learning Path includes content from the following Packt products:</p> <p><span style="background-color: transparent;">•Angular 6 by Example by Chandermani Arora, Kevin Hennessy&nbsp;</span><br /><span style="background-color: transparent;">•Architecting Angular Applications with Redux, RxJS, and NgRx by Christoffer Noring</span><br /><span style="background-color: transparent;">•Angular 6 for Enterprise-Ready Web Applications by Doguhan Uluca</span></p>

We now have an app that can do a lot of stuff. It can run workouts, load workouts, save and update them, and track history. And if we look back, we have achieved this with minimal code. We bet that if we were to try this in standard jQuery or some other framework, it would require substantially more effort as compared to Angular.

We started the chapter by providing a MongoDB database on MongoLab servers. Since MongoLab provided a RESTful API to access the database, we saved some time by not setting up our own server infrastructure.

The first Angular construct that we touched upon was the HTTPClient, which is the primary service for connecting to any HTTP backend.

You also learned how the HTTPClient module uses Observables. For the first time, in this chapter, we created our own Observable and explained how to create subscriptions to those Observables.

We fixed our Personal Trainer app so that it uses the HTTPClient module to load and save workout data (note that data persistence for...
