I think I'd prefer Lezer in a javascript-only setting. The results are compact and you don't have to deal with WASM.

I've written a small tree-sitter grammar, with off-side rule even, and had a bunch of issues with the javascript bits not being the same version as the WASM bits. I ended up having to get just the right version of emscripten installed (and maybe a few other tools). The process felt a bit fragile to me.
