Hands-On Dependency Injection in Go

Hands-On Dependency Injection in Go

Corey Scott









Explore various dependency injection methods in Go such as monkey patching, constructor injection, and method injection

Key Features

Learn to evaluate Code UX and make it better

Explore SOLID principles and understand how they relate to dependency injection

Use Google's wire framework to simplify dependence management

Book Description

Hands-On Dependency Injection in Go takes you on a journey, teaching you about refactoring existing code to adopt dependency injection (DI) using various methods available in Go.

Of the six methods introduced in this book, some are conventional, such as constructor or method injection, and some unconventional, such as just-in-time or config injection. Each method is explained in detail, focusing on their strengths and weaknesses, and is followed with a step-by-step example of how to apply it. With plenty of examples, you will learn how to leverage DI to transform code into something simple and flexible. You will also discover how to generate and leverage the dependency graph to spot and eliminate issues. Throughout the book, you will learn to leverage DI in combination with test stubs and mocks to test otherwise tricky or impossible scenarios.

Hands-On Dependency Injection in Go takes a pragmatic approach and focuses heavily on the code, user experience, and how to achieve long-term benefits through incremental changes.

By the end of this book, you will have produced clean code that's easy to test.

废话太多, 感觉一篇blog能说清楚的事,搞了一本书。
DI 多半是为了更好地进行单元测试!!!
我看的是京东阅读的 epub 版本。示例代码没有高亮,没有出处,刚刚开始看的有点不值所云。后来,使用了文本对比软件,才找到了打开这一本书的正确方式。总的来说,作者还是有干活提供的,但是表达方式有点问题。
