wasm-cellular-automata

This project is an implementation of Conway's Game of Life using Rust and WebAssembly. The game is rendered on a canvas in the browser.

Technologies Used

  • Rust
  • WebAssembly
  • JavaScript
  • TypeScript
  • Vite

Project Structure

The project is divided into two main parts:

  1. The Rust and WebAssembly part, which is responsible for the game logic.
  2. The TypeScript part, which is responsible for rendering the game and handling user interactions.

Rust and WebAssembly

The Rust code is located in the src directory. The main logic of the game is implemented in the Universe struct in src/lib.rs. The Universe struct represents the game universe and includes methods for creating a new universe, getting and setting the state of cells, and updating the universe for each tick of the game.

The Rust code is compiled to WebAssembly using the wasm-pack tool. The compiled WebAssembly code is located in the pkg directory.

TypeScript

The TypeScript code is located in the app/src directory. The main.ts file is the entry point of the application. It sets up event listeners for user interactions and starts the game loop. The universe.ts file imports the Universe class from the compiled WebAssembly code. The canvas.ts file handles rendering the game universe on a canvas.

Running the Project

Compiled .wasm modules are already available in the repository, but you can compile it again yourself if you have Rust and wasm-pack installed.

To run the project, you must have at least and npm installed.

First, compile the Rust code to WebAssembly (you can skip this step if you don't have Rust and wasm-pack installed):

wasm-pack build

Then, install the npm dependencies:

cd app
npm install

Finally, start the development server:

npm run dev

The game will be available at http://localhost:[Port that Vite will choose].

Testing

The project includes tests for the Universe struct. The tests are located in the tests directory. You can run the tests with the following command:

wasm-pack test --chrome
