“WebAssembly on the server is the future of computing.”
–Solomon Hykes, founder of Docker
Learn how to harness the power of Wasm on the application back-end. By following the numerous practical examples and crystal-clear explanations, you’ll soon be seeing the benefits of reduced cold start times, improved security and performance, and the freedom of polyglot programming.
This book lays out everything you need to take WebAssembly beyond its traditional browser domain. You’ll put on the hats of a systems architect, a backend developer, and even a DevOps engineer to get a full picture of WebAssembly development from both an architecture and development perspective.
Inside Server-Side WebAssembly you’ll learn how to:
• Develop and deploy server-side Wasm applications
• Create and manage Wasm containers with OCI
• Compile Wasm components from multiple languages
• Scale Wasm applications using Kubernetes
• Deploy Wasm applications across different environments
• Integrate with databases and machine learning
About the technology
WebAssembly (Wasm) revolutionized frontend development by enabling secure, high-performance code in the browser. Now it’s doing the same for backend infrastructure as a platform for lightweight, portable applications that run anywhere. In this book, you’ll learn how to build production-grade server-side apps using Wasm.
About the book
Server-Side WebAssembly teaches you to use WebAssembly components and the WebAssembly System Interface (WASI) to build web back ends. You’ll start with Wasm fundamentals and then quickly start building a realistic content management system complete with data storage, HTTP servers, and AI-generated content. As you go, you’ll see how Wasm integrates code from multiple languages and connects naturally with databases, AI/ML systems, and deployment platforms like Kubernetes.
What's inside
• Integrate components from multiple languages
• Deploy Wasm applications on Kubernetes
• Connect Wasm apps to databases and ML systems
About the reader
For intermediate web developers. Code samples in Rust, JavaScript and Python.
