Overview
The article introduces Ruvy, an open-sourced toolchain that converts Ruby code into WebAssembly (Wasm) modules. It highlights Ruvy's performance advantages over existing solutions like ruby.wasm, particularly through pre-initialization of the Ruby virtual machine and simplified execution without WASI arguments.

Key Questions Answered
What are the main advantages of using Ruvy over ruby.wasm?
Ruvy offers significant performance improvements by pre-initializing the Ruby virtual machine and eliminating the need for WASI arguments during execution. This results in faster runtime performance, making it suitable for environments where runtime configuration is limited.
How does Ruvy simplify the execution of Ruby code in WebAssembly?
Ruvy simplifies execution by not requiring WASI arguments, which are typically needed to specify file paths for Ruby scripts. This makes Ruvy compatible with various edge computing environments that cannot provide such arguments.
What performance benchmarks were observed when using Ruvy?
Ruvy modules demonstrated a runtime performance improvement of approximately 20% compared to ruby.wasm modules. For example, the 'Hello world' execution time was reduced from 55.833 ms with ruby.wasm to 44.367 ms with Ruvy.
