Shrink your services, not your ambitions. Traditional backends often feel heavy, costly, and slow to adapt. Server-Side WebAssembly shows you how to build lightning-fast, portable backends that run anywhere, giving you the power of Wasm without the pain of complex rewrites.
- Polyglot components: Reuse Rust, JavaScript, and Python code without rewrites.
- OCI-compliant containers: Package Wasm workloads once, deploy on any registry or platform.
- Kubernetes scaling: Orchestrate tiny binaries that launch in milliseconds and slash cloud bills.
- Edge readiness: Serve users closer, lower latency, and maximise device performance.
- Built-in security: Sandboxed execution reduces attack surface for production workloads.
- Hands-on project path: Key-value, HTTP, and ML components show real workflows step by step.
Serve- Side WebAssembly by WebAssembly contributor Danilo Chiarlone delivers a clear, code-first roadmap for next-gen back-end development.
Starting with essential Wasm fundamentals, the book moves quickly into building production-grade microservices. You containerise components, push them to registries, and integrate with Kubernetes, serverless, and edge platforms. Each chapter layers new skills through a running sample app.
By the final page, you will confidently compile, package, and scale Wasm workloads from multiple languages, tap hardware isolation, and connect to cloud resources and machine-learning models.
Ideal for backend developers, DevOps engineers, and system architects seeking leaner, faster, portable services.
