DuckDB works on Val Town, with only one small tweak! We're basically using DuckDB in the same way you'd use it with a browser - using the WASM package with its dependencies fetched from jsdelivr.

The only trick is to create the worker ourselves rather than using duckdb.createWorker. DuckDB's built-in createWorker method doesn't specify a worker type, which causes type to default to classic, and Deno (our runtime) doesn't support classic workers.
