install_duckdb_wasm: Install the DuckDB-WASM binary for large-dataset virtualization

Description

Downloads and verifies the DuckDB-WASM runtime into a user-local cache so the in-browser big-data engine is available for subsequent widgets. This follows the keras3 / torch / reticulate pattern: the binary is NOT bundled with the R package and is not required for small-data use.

Usage

install_duckdb_wasm(
  version = NULL,
  from = NULL,
  force = FALSE,
  quiet = !interactive()
)

Value

Invisibly returns the cache path where the binary was installed.

Arguments

version

Character scalar naming the version to install. Defaults to the latest row in `inst/duckdb-wasm-manifest.csv`.

from

Optional local directory containing pre-downloaded binaries (`duckdb-mvp.wasm` and `duckdb-browser-mvp.worker.js`). Airgap path.

force

Logical. If TRUE, overwrite existing cached binaries.

quiet

Logical. Suppress progress output. Defaults to `!interactive()`.

Examples

if (FALSE) {
# Downloads ~22 MB from the upstream mirror into the user cache.
install_duckdb_wasm()
}
