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>

Angular and server interactions


Any client-server interaction typically boils down to sending HTTP requests to a server and receiving responses from a server. For heavy JavaScript apps, we depend on the AJAX request/response mechanism to communicate with the server. To support AJAX-based communication, Angular provides the Angular HttpClient module. Before we delve into the HttpClient module, we need to set up our server platform that stores the data and allows us to manage it.

Setting up the persistence store

For data persistence, we use a document database called MongoDB (https://www.mongodb.com/), hosted over MongoLab (https://www.mlab.com/), as our data store. The reason we zeroed in on MongoLab is that it provides an interface to interact with the database directly. This saves us the effort of setting up server middleware to support MongoDB interaction.

Note

It is never a good idea to expose the data store/database directly to the client. But in this case, since our primary aim is to learn...
