Mastering TypeScript 3 - Third Edition

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.

Database-driven APIs

In order to provide the data that is needed for this application, we will store and retrieve data from a traditional database. We will provide a REST endpoint for each of our database tables that we will need. Node supports a wide variety of databases, including traditional relational databases such as Oracle or SQL Server, or object databases such as MongoDB or CouchDB. For the sake of this exercise, we will use Sqlite3 as a backing database.

Sqlite3 is a very small, fast, and self-contained database engine. It supports SQL language queries and standard table structures, and is contained within a single file on disk, or even as an in-memory temporary database. It can be installed on Windows, Linux, and macOS, and has a very small footprint. Sqlite3 also has some very simple, yet powerful, GUI tools to help with database design and data input, such as DB Browser...
