Books

Do you want to write beautiful, structured, and maintainable JavaScript by applying modern design patterns to the language? Do you want clean, efficient, manageable code? Want to stay up-to-date with the latest best practices? If so, the updated second edition of Learning JavaScript Design Patterns is the ideal place to start.

Author Addy Osmani shows you how to apply modern design patterns to JavaScript and React. That includes popular design patterns such as modules, mixins, observers, and mediators. You'll learn about performance and rendering patterns, such as server-side rendering and islands architecture. You'll also learn how modern architectural patterns—such as MVC, MVP, and MVVM—are useful from the perspective of a modern web application developer. Other essential topics include modern JavaScript syntax and React patterns such as Hooks, higher order components, and render props.

In Software Engineering - The Soft Parts Addy Osmani shares lessons from his first 10 years at Google on the soft skills that can help engineers become effective and scale their effectiveness. This guidance should help junior, mid-career and even senior developers move forward, deal with changing technology, and navigate building non-trivial systems. Becoming a good engineer is about collecting experience. Each project, even small ones, is a chance to add new techniques and tools to your toolbox. Where this delivers even more value is when you can solve problems by pairing techniques learned on one project with tools learned working on another. This short book tries to capture what the soft skills are and how they can all add up.

Success at Scale is a curated collection of best-practice case studies capturing how production sites of different sizes tackle performance, accessibility, capabilities, and developer experience at scale. Case studies are from industry experts with guidance that stands the test of time.
