Nothing else. Talent helps, coincidences might happen, luck is possible. But for 99% of people, none of these things work. Hard work is the key. I'd like to thank my family first for understanding that projects like this, along with the daily work on code, require a lot more time than just 9-to-5. I really appreciate silent nights at the computer.Also, again, the team at Apress was very helpful during this project, with the right mixture of time and pressure to get it done on schedule. Thank you all for the opportunity to write about a subject I really care about a lot. Sometimes it's hard, but there is always a way to see things positively. Even the biggest catastrophes may have an upside. Looking straight into the darkness might make it hard to see this. But there is one, for sure. This book and the library code used as the foundation were written during the pandemic in 2020. The upside was the leisure time not spent with friends, at holidays, or other activities. Not good, of course, but some new things learned, some pieces tried, some more lines written...you get the idea, I hope.xxi Create professional and progressive web apps with the native HTML API on the latest technology stack. This book describes the basics of web components and how to create them using plain JavaScript as well as how to make professional applications based on web components using TypeScript. Developing Web Components with TypeScript looks at APIs using examples, techniques, and tricks. You will start with a brief introduction to web components, including slots and templates, handling custom events, and styling components with or without shadow DOM. Then, it introduces TypeScript as part of the tool set. It shows the internal construction of a professional thin library. It also helps you learn how to deal with web components in real-life projects; this includes techniques such as creating a single-page app without framework code. All code samples used here are supported by all modern browsers for you to follow along. Library code and examples are available on GitHub. What You Will Learn Create isolated web components using shadow DOM, slots, and templates Understand the advantage of an enhanced toolset, especially TypeScript Pick up styles and customizations Master professional web apps using native APIs Understand the life cycle of a component Who This Book Is For Professional developers who want to move from desktop to web and away from fat frameworks to achieve their goal.
