Angular for Enterprise-Ready Web Applications - Second Edition

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.

Production readiness

When you run npm start, Angular builds in debug mode, which enables faster build times, breakpoint debugging, and live reloading. This also means that the bundle size of a small app balloons to over 7 MB. A 7 MB bundle size results in over two minutes of loading time on a slow 3G connection when we expect our app to load in mere seconds. Additionally, in debug mode, we use environment variables meant for local development. However, in production, we need to use different settings so our application can run in a hosted environment correctly.

Let's start by implementing an npm script to help us build in prod mode.

Building for production

Angular ships with a robust build tool that can optimize the size of your bundle by removing redundant, unused, and inefficient code from the debug build and pre-compiling sections of code so browsers can interpret it faster. So, a 7 MB bundle can become 700 KB and load in under 7 seconds even on a slow 3G connection...
