Minimal MVP for a browser-based CSV viewer/editor built with Rust + wasm.

What it includes

• CSV import into an in-memory table model
• Virtualized grid rendering so only the visible rows mount in the DOM
• Editable source cells
• Calculated columns powered by Boa from Rust
• Worker-based parallel execution for larger formula runs
• A synthetic sample dataset for immediate demoing

Build a runnable site

Build the site bundle:

./scripts/build-dist.sh

This creates dist/, which contains the HTML shell, the local icon module, and the generated pkg/ output.

Deploy with Wrangler

Wrangler is configured to deploy the built static site from dist/ and to run the build step automatically during deploy.

wrangler deploy

If you prefer the npm alias:

npm run deploy

Run it

Serve dist/ from a local static server:

python3 -m http.server 8080 --directory dist

3. Open http://localhost:8080.

Notes

• wasm-pack build only generates the wasm package in pkg/. It does not create index.html.
• The app entry files live at the project root and are copied into dist/ by the build script.
