This blog post details the author's process of creating a Checkers game using Rust and compiling it to WebAssembly (WASM) for play in a web browser. The author highlights the benefits of using Rust, such as performance and memory safety, and the relative ease of targeting WASM. They describe key implementation aspects, including game logic, board representation, and user interface interaction using the Yew framework. The post also covers setting up the Rust and WASM build environment, and optimizing the WASM module size for faster loading. The final result is a playable checkers game embedded directly in the webpage, demonstrating the practicality of Rust and WASM for web development.
Kevin Albertson's blog post details the process and learnings from creating a checkers game implemented in the Rust programming language and subsequently compiled to WebAssembly (WASM) for deployment in a web browser. The project leverages the Yew framework, a Rust framework specifically designed for building front-end web applications with WASM as the compilation target. This allows the game logic, written in Rust, to execute efficiently within the client's browser.
Albertson describes a straightforward game implementation, focusing on the core mechanics of checkers, including move validation, capturing, and king promotion. He explains how the game board is represented and how user interactions are translated into game actions. The post highlights the benefits of using Rust, such as memory safety and performance, which translate to a robust and responsive web application. The compilation to WASM is a key aspect of the project, enabling near-native performance within the browser environment.
The blog post also delves into the integration of the WASM module with the web frontend. It explains how JavaScript is used as a bridge to interact with the WASM code, handling user input and updating the visual representation of the game on the webpage. The post likely includes snippets of code demonstrating key aspects of the implementation, both on the Rust/WASM side and the JavaScript side, showing how the two parts communicate. Furthermore, the post likely discusses the build process and the tools involved in compiling Rust to WASM and integrating it with the web application. The author possibly reflects on the experience of using Yew and the advantages it provides for building web applications with Rust and WASM, touching upon the developer experience and the overall ease of development.

HN commenters generally praised the clean and performant implementation of Checkers in Rust and WASM. Several lauded the clear code and the educational value of the project, finding it a good example of Rust and WASM usage. Some discussed performance considerations, including the choice of using a 1D array for the board representation, suggesting a 2D array might offer better readability despite potentially slightly reduced performance. A few comments touched on potential enhancements, like adding an AI opponent or allowing undo/redo functionality. There was also minor discussion around alternative approaches to game development with Rust/WASM and other languages.
The Hacker News post titled "Checkers written in Rust and exported to WASM" (https://news.ycombinator.com/item?id=43364776) has a moderate number of comments discussing various aspects of the project and related technologies.
Several commenters praise the clean and simple implementation of the game, appreciating the author's focus on a straightforward approach rather than over-engineering. One user specifically highlights the value of this as a learning resource for those interested in Rust and WASM, noting it's more accessible than more complex examples.
A significant portion of the discussion revolves around the choice of Rust and WASM. Some users express enthusiasm for Rust's performance characteristics and memory safety features, seeing them as ideal for web-based game development. Others discuss the benefits of WASM for portability and performance. One commenter points out that WASM's ability to be run in various environments makes it a good choice for projects like this.
The use of the Yew framework is also a topic of conversation. Commenters familiar with Yew express their positive experiences with it. One user mentions its similarity to React, making it easier to learn for those coming from a JavaScript background.
Performance is touched on in several comments. One commenter questions the necessity of WASM for a simple game like checkers, suggesting that JavaScript might be sufficient. Another counters this, arguing that WASM offers performance advantages even for simpler games, particularly in scenarios with more complex logic or AI. There's also some discussion around the size of the WASM binary and potential optimizations.
Beyond the technical aspects, some comments focus on the user experience. One commenter suggests improvements to the UI, such as highlighting possible moves. Another appreciates the minimalist design.
In summary, the comments generally express positive sentiment towards the project, praising its simplicity, the technology choices, and its potential as a learning resource.
