Four Approaches to Debugging Server-side WebAssembly - Shopify

This post details four distinct approaches to debugging server-side WebAssembly: compiling to a native architecture and using language-specific debuggers (like LLDB/GDB for Rust), using LLDB with Wasmtime to debug Wasm code in a Wasm environment, utilizing WebAssembly-specific debuggers (like Wasminspect), and leveraging browser developer tools (like Chrome DevTools with DWARF support). It outlines the trade-offs for each, including variable rendering fidelity, environment similarity, feature set, and setup complexity, concluding that native debugging offers the best experience for most cases, while Wasmtime/LLDB and browser debuggers are viable alternatives for Wasm-specific issues.
