Overview of this book

Building Blazor WebAssembly Applications with gRPC will take you to the next level in your web development career. After working through all the essentials of gRPC, Blazor, and source generators, you will be far from a beginner C# developer and would qualify as a developer with intermediate knowledge of the Blazor ecosystem. After a quick primer on the basics of Blazor technology, REST, gRPC, and source generators, you’ll dive straight into building Blazor WASM applications. You’ll learn about everything from two-way bindings and Razor syntax to project setup. The practical emphasis continues throughout the book as you steam through creating data repositories, working with REST, and building and registering gRPC services. The chapters also cover how to manage source generators, C# and debugging best practices, and more. There is no shorter path than this book to solidify your gRPC-enabled web development knowledge. By the end of this book, your knowledge of building Blazor applications with one of the most modern and powerful frameworks around will equip you with a highly sought-after skill set that you can leverage in the best way possible.

What are the benefits of using gRPC services?

gRPC is a powerful, language-neutral open source framework. Using TCP connection and binary serialization is more powerful and faster than the standard REST API communication with JSON serialization used in all JavaScript frameworks. gRPC also uses the HTTP/2 protocol instead of the older HTTP/1.1.

The problem with gRPC is that it is a protocol primarily created for client-to-server communication, where the client is another server and both the client and server must support the HTTP/2 protocol. Browsers, on the other hand, do not support HTTP/2 yet.

This is where the Blazor comes in. Blazor, despite being the client WebAssembly part of the application, runs in the browser, supports the gRPC protocol, and allows us to use this powerful tool.

Here are the main benefits of using the gRPC protocol:

  • Binary serialization: The protocol produces smaller messages than JSON, but it is not human-readable. Binary serialization converts...
