Extensions
Default extensions currently enabled in DuckDB-Wasm are Parquet and FTS. HTTPFS is a specific re-implementation that comes bundled by default.
JSON and Excel are build-time opt-in.
Dynamic (= runtime) extension loading
Dynamic extension loading is currently experimental, participate in the tracking issue or try it on the experimental deployment at: https://shellwip.duckdb.org.
