WebAssembly is a groundbreaking technology that has transformed the way we build and deploy web applications. It enables lightning-fast performance, portability across platforms, and seamless integration with existing web technologies. This comprehensive guide will lead you through the journey of mastering WebAssembly, from its fundamentals to advanced applications.

This book introduces WebAssembly basics, its purpose, and real-world use cases in web, server, and desktop apps. Featuring examples in languages like AssemblyScript, C/C++, and Rust, it covers converting legacy codebases to WebAssembly for browser compatibility. It showcases advanced use cases like WebAssembly-based music tools, Git integration, and smart contracts. The book concludes with WebAssembly's role in cloud-native Kubernetes, signaling a new era in container orchestration. Many of the examples build on the author's experience with WebAssembly Music, git in WebAssembly, and NEAR protocol smart contracts. These examples serve as real-world use cases, more than just a basic introduction to the technology.

By the end of this book, you will have gained the knowledge and skills to confidently build, deploy, and optimize high-performance WebAssembly applications across a wide range of platforms and use cases.

Store Description

We first started out as ?The Paperback Exchange,? a chain of physical bookstores where we would part exchange your beloved books for new stories to transport you to faraway places. However, as shopping started to evolve to online shops and marketplaces, we bid our stores goodbye to become ?PBShop.? This transition has only allowed us to blossom as we now ship thousands of titles to book lovers across the globe. We pride ourselves in being a community of local book lovers which allows our passion and devotion to shine in everything we do. In 2020 we not only celebrated our 20th birthday but our 1st birthday as being completely employee owned after becoming an E.O.T in September 2019. We are proud to be different and embrace standing apart on a book mountain by working from a virtual inventory which allows us to provide thousands of books that may be difficult to get for your bookshelf or your studies. Working with a number of different suppliers allows us to explore other avenues such as puzzles, sheet music and even stationery so we really do have something for everyone. Life is about being versatile in all realms of existence. If this is your first visit or you are a returning customer, we would like to welcome you to the PBShop family, for there is no friend as loyal as a book. We are a company who put our customers at the centre of everything we do as we understand the importance of reading because once you learn to read, you will forever be free. There are a whole lot of things in this world of ours that we are yet to explore, which is why we will forever inspire curious minds.
