TypeScript Design Patterns

Overview of this book

In programming, there are several problems that occur frequently. To solve these problems, there are various repeatable solutions that are known as design patterns. Design patterns are a great way to improve the efficiency of your programs and improve your productivity. This book is a collection of the most important patterns you need to improve your applications’ performance and your productivity. The journey starts by explaining the current challenges when designing and developing an application and how you can solve these challenges by applying the correct design pattern and best practices. Each pattern is accompanied with rich examples that demonstrate the power of patterns for a range of tasks, from building an application to code testing. We’ll introduce low-level programming concepts to help you write TypeScript code, as well as work with software architecture, best practices, and design aspects.

Modularizing project

Before ES6, there were a lot of module solutions for JavaScript that worked. The two most famous of them are AMD and commonjs. AMD is designed for asynchronous module loading, which is mostly applied in browsers, while commonjs does module loading synchronously, and that's the way the Node.js module system works.

To make it work asynchronously, writing an AMD module takes more characters. And due to the popularity of tools such as browserify and webpack, commonjs becomes popular even for browser projects.

The proper granularity of internal modules could help a project keep its structure healthy. Consider a project structure like this:

│  │ index.ts 
│  │ 
│  ├─product 
│  │   index.ts 
│  │   order.ts 
│  │   shipping.ts 
│  │ 
│  └─user 
│      index.ts 
│      account.ts 
│      statistics.ts
