There was a problem hiding this comment.
Bug: The use of Buffer.from() in code compiled for the browser may cause a ReferenceError because Buffer is not a standard browser global.
Severity: MEDIUM
🔍 Detailed Analysis
The code at src/bundles/wasm/src/wabt.ts uses Buffer.from(buffer). This file is compiled for a browser environment where the Buffer global is not natively available. Unless the build process is configured to polyfill Buffer, this will likely cause a ReferenceError: Buffer is not defined at runtime when the wrun function is executed, preventing the WebAssembly module from being instantiated.
💡 Suggested Fix
Remove the Buffer.from() call. The WebAssembly.Module constructor can accept a Uint8Array or ArrayBuffer directly, which buffer is likely to be. The line should be changed to const wasmModule = new WebAssembly.Module(buffer);.

Potential issue: The code at `src/bundles/wasm/src/wabt.ts` uses `Buffer.from(buffer)`.
This file is compiled for a browser environment where the `Buffer` global is not
natively available. Unless the build process is configured to polyfill `Buffer`, this
will likely cause a `ReferenceError: Buffer is not defined` at runtime when the `wrun`
function is executed, preventing the WebAssembly module from being instantiated.
