By: Doguhan Uluca

Overview of this book

This second edition of Angular for Enterprise-Ready Web Applications is updated with in-depth coverage of the evergreen Angular platform. You’ll start by mastering Angular programming fundamentals. Using the Kanban method and GitHub tools, you’ll build great-looking apps with Angular Material and also leverage reactive programming patterns with RxJS, discover the flux pattern with NgRx, become familiar with automated testing, utilize continuous integration using CircleCI, and deploy your app to the cloud using Vercel Now and GCloud. You will then learn how to design and develop line-of-business apps using router-first architecture with observable data anchors, demonstrated through oft-used recipes like master/detail views, and data tables with pagination and forms. Next, you’ll discover robust authentication and authorization design demonstrated via integration with Firebase, API documentation using Swagger, and API implementation using the MEAN stack. Finally, you will learn about DevOps using Docker, build a highly available cloud infrastructure on AWS, capture user behavior with Google Analytics, and perform load testing. By the end of the book, you’ll be familiar with the entire gamut of modern web development and full-stack architecture, learning patterns and practices to be successful as an individual developer on the web or as a team in the enterprise.

Code coverage reports

A good way to understand the amount and the trends of unit test coverage for your Angular project is through a code coverage report.

In order to generate the report for your app, execute the following command from your project folder:

$ npx ng test --browsers ChromiumNoSandbox --watch=false --code-coverage

The resulting report will be created as an HTML file under a folder named coverage; execute the following command to view it in your browser:

$ npx http-server -c-1 -o -p 9875 ./coverage

Install http-server as a development dependency in your project.

Here's the folder-level sample coverage report generated by istanbul/nyc for LemonMart:

You can drill down on a particular folder, such as src/app/auth, and get a file-level report, as shown here:
