If you're unable to rapidly ship changes to your code without introducing new bugs or causing outages, perhaps it's time to slow down and consider a significant refactor. With this practical guide, software engineer Maude Lemaire teaches you how to identify and solve problematic patterns in your codebase. You'll learn techniques to help you effectively plan and execute a refactor spanning extensive surface areas of your application. Drawing from Lemaire's experience driving performance and refactoring efforts at Slack during a period of critical growth, this book helps you achieve newfound developer productivity throughout your organization. You'll learn how to: Identify the benefits of refactoring: bug squashing, developer productivity, and performance optimization Understand and articulate what's wrong with your current code Document and measure the impact of a refactoring effort Bring together the best team for the job Build sustainable coding practices and a healthier codebase
