The author details the technical challenges of integrating Go into an isolated V8 environment for a browser-based coding platform, specifically addressing the incompatibility between Go's async WASM boot process and synchronous execution contexts. Standard methods using GOOS=js fail due to Promise handling issues within isolated-vm, requiring custom workarounds beyond typical tutorials.
Background
Browser-based coding platforms often need to support multiple languages by compiling them to WebAssembly or using interpreters like Pyodide. Running untrusted user code securely typically requires isolation from the main thread and DOM.
