Ryan Hunt (Aug 13 2025 at 14:47): Ryan Hunt (Aug 13 2025 at 14:47):Hi all! I just wanted to share a quick project I worked on that may be of interest to folks here: github.com/eqrion/wasm-explorer (https://eqrion.github.io/wasm-explorer)
It's a web based viewer for wasm modules built using componentized versions of the wasm-tools crates (originally a fork of the sandbox from that repo). My hope is to optimize it to work really well for huge wasm modules (+50MiB) where simply opening the text format in an text viewer is not a good experience. It virtualizes the wasm module text format so you navigate through the AST using search, cross references, and a tree view.
It's pretty early, so there may be bugs. I have a small roadmap of features I hope to add over time, contributions are welcome.
Pat Hickey (Aug 13 2025 at 14:59):Love it! any plans to extend it to support components? It seems to just do nothing when I open one of those :)
Ralph (Aug 13 2025 at 15:01):same here
Ralph (Aug 13 2025 at 15:01):because I was sooooo excited to try one!
Ryan Hunt (Aug 13 2025 at 15:06):Yes, that's one of the next things I'd like to do. I hope it won't be too bad, but I might need to refactor some of the virtualization/AST code to be less hacky to get it to work well.
Ralph (Aug 13 2025 at 15:08):def ping when you want us to try -- I got large components waiting
bjorn3 (Aug 13 2025 at 15:11):It kinda gets stuck for me on https://github.com/bjorn3/wasm-rustc/blob/main/bin/rustc.wasm which is 77MB.
bjorn3 (Aug 13 2025 at 15:12):Or at least it is very slow.
bjorn3 (Aug 13 2025 at 15:13):And firefox uses 5GB when loading that file.

Sorry, read that as that you already did optimizations.
bjorn3 (Aug 13 2025 at 15:15):Slowness on my rather large wasm module aside, it does look pretty.
