Overview of this book

TypeScript is both a language and a set of tools to generate JavaScript. It was designed by Anders Hejlsberg at Microsoft to help developers write enterprise-scale JavaScript. Starting with an introduction to the TypeScript language, before moving on to basic concepts, each section builds on previous knowledge in an incremental and easy-to-understand way. Advanced and powerful language features are all covered, including asynchronous programming techniques, decorators, and generics. This book explores many modern JavaScript and TypeScript frameworks side by side in order for the reader to learn their respective strengths and weaknesses. It will also thoroughly explore unit and integration testing for each framework. Best-of-breed applications utilize well-known design patterns in order to be scalable, maintainable, and testable. This book explores some of these object-oriented techniques and patterns, and shows real-world implementations. By the end of the book, you will have built a comprehensive, end-to-end web application to show how TypeScript language features, design patterns, and industry best practices can be brought together in a real-world scenario.

Using continuous integration

When writing unit tests for any application, it quickly becomes important to set up a build server and run your tests as part of each source control check in. When your development team grows beyond a single developer, using a continuous integration build server becomes imperative. This build server will ensure that any code committed to the source control server passes all known unit tests, integration tests, and automated acceptance tests. The build server is also responsible for labeling a build, and generating any deployment artifacts that need to be used during deployment. The basic steps of a build server are as follows:

  • Check out the latest version of the source code, and increase the build number
  • Compile the application on the build server
  • Run any server-side unit tests
  • Package the application for deployment
  • Deploy the package to a build environment...
