Full-Stack Rust Web Apps [Bundle of 3 books]

This book is for you if you're tired of watching JavaScript struggle with complicated calculations while your users get impatient. I wrote this second edition because WebAssembly 2.0 changes everything, and I wanted to show you exactly how to use it without the usual technical book problems.

The first thing we'll do is go through the basics, like memory management and control flow, which are the most important. Then we'll move on to putting together C, C++, Rust, and Python into Wasm modules that actually work. I'll show you how to use multi-threading, profiling and optimisation techniques that I've used in real projects, not just theoretical exercises. I know a lot of you have old Wasm 1.0 code, so I've written a whole chapter about how to move it over without causing any problems. And we'll also learn how to use WebAssembly in other ways, not just in browsers. You'll learn to work with Dapr for distributed microservices, deploy on Kubernetes, and build cloud-native applications that scale well.

There is working code in every chapter that you can use right away. There is no unnecessary information, just practical techniques that solve real problems. I've figured out the tricky parts and the things that can go wrong, and I'm sharing them what actually works. By the time you finish this book, it will have taught you everything you need to build WebAssembly applications so quickly that people will be amazed.

Key Features

• Put together C, C++, Rust, and Python into high-performance WebAssembly modules using Emscripten.
• Build advanced multi-threaded apps using atomic operations, shared memory and thread-safe sync patterns.
• Migrate old Wasm 1.0 projects to version 2.0 using proven strategies.
• Combine WebAssembly with Dapr for microservices using patterns for managing data and sending messages.
• Deploy and scale Wasm workloads on Kubernetes clusters with complete control over configuration and secrets management.
• Make performance better by using systematic profiling and advanced compilation techniques for production apps.
• Take care of module imports, exports, and JavaScript interoperability.
• Use tables, memory semantics and dynamic dispatch mechanisms for complex logic.
• Manage networking, security, monitoring, and debugging for WebAssembly cloud-native deployments at scale.

Whether you're just starting out or a fully-fledged Rust pro, this third Edition is a goldmine of knowledge about Rust. This book has been updated with Rust 1.85 and Rust 2024 Edition, and it takes you on a really structured learning path to write production-grade systems, async services, GPU compute kernels, Linux kernel modules, and Go-integrated libraries.

The book is built around a single, progressive application, and every chapter adds a functional layer to a real Linux system-metrics tool. The knowledge you gain from this book, is working and evolving codes that you can study, extend, and own. You'll get the hang of ownership and borrowing, handle the borrow checker, build concurrent and async programs with Tokio, manage memory without a garbage collector, and use Rust in domains that were once reserved exclusively for C and C++.

Whatever stage you're at, whether you're just starting out and writing your first function or you're a seasoned engineer migrating a critical service to Rust, this strong practically focussed book has got you covered.

• Dive in-depth into ownership model and eliminate memory bugs at compile time.
• Build async, concurrent programs using Tokio without data races or deadlocks.
• Design production-grade error types with ‘thiserror’ and ‘anyhow’ crates.
• Write GPU compute kernels and monitor GPU metrics.
• Integrate Rust libraries into existing Go applications via application binary interfaces.
• Write a loadable Linux kernel module entirely.
• Manage heap memory using Box, Rc, Arc, and smart pointer types.
• Leverage Rust 2024 Edition's new safety rules and migration workflow.
• Make use of Cargo workspaces, features, and optional dependencies to structure projects.

This book isn't for practice, but to test out the architecture. All you are learning in this book, is build a full-stack Rust application, on Axum, and then rebuild it again on Actix Web 4, and the domain crate won't change at all. Under both, you'll find a pinned Rust 1.95 and edition 2024 toolchain, business rules that don't rely on any framework, and PostgreSQL accessed through SQLx with queries and transactions that are verified at compile time.

When you're done there, you'll have versioned REST APIs and a GraphQL schema, OAuth2 sign-in with GitHub, JWT claims and Argon2 hashing, and a reactive Leptos storefront compiled to WebAssembly. With WebSockets, you can stream live updates, size Tokio runtimes and connection pools by measurement, then ship to Kubernetes through a gated pipeline. The idea is not to turn you into a Rust expert overnight, but to equip you with the knowledge to build something that will keep on going long after its dependencies are obsolete.

• Separate business rules into a domain crate depending on no framework, database or runtime.
• Build asynchronous web services on Axum with typed state, extractors and tower middleware.
• Rebuild same server on Actix Web 4 and work with per-worker arbiter model.
• Query PostgreSQL through SQLx using reversible migrations and transactions.
• Publish versioned REST APIs and a GraphQL schema with DataLoader batching.
• Add OAuth2 sign-in with GitHub, JWT claims and Argon2 password hashing.
• Build reactive Leptos front-end compiled to WebAssembly, with server-side rendering.
• Stream live updates over WebSockets, and tune Tokio runtimes and connection pools.
• Containerize with Docker and cargo-chef, and ship to Kubernetes through CI pipeline.
