.io Game

TODO

Tech Stack

Backend

• Backend written in Elixir
• Phoenix
  • Phoenix Channels for communication between the frontend + backend

Messaging + Serialization

• WebSocket-based communication between the backend and the frontend using Phoenix channels
• Binary message serialization using Protcol Buffers.
• All messages are tagged with a UUID that corresponds to some entity.
  • The "universe" can be an entity for general messages as well (UUID 0000-0000...?)

Frontend

• Built with Rust and compiled into WebAssembly
• Uses the Phoenix channels JS client library as a wrapper to connect to the backend and relay data to the WebAssembly code that powers the game.

Installation

Backend

• Install Elixir with brew install elixir
• Install all deps within backend with mix deps.get
• Compile and start server with mix phx.server

Frontend

• You'll need to install Rust in order to build the frontend. I suggest using Rustup.
• Run rustup toolchain install nightly to install the nightly toolchain
• Run rustup default nightly to make the nightly toolchain default.
• Run rustup target add wasm32-unknown-unknown --toolchain nightly to add the WebAssembly target.
• Run cargo install wasm-bindgen-cli to install the wasm-bindgen-cli which is used to generate JS wrapper code and TypeScript definitions from WebAssembly files.
