Cannot load WASM - initWasm TypeError: fetch failed

[MengLinMaker]

When I call initWasm, the program fails.

I am running Node 25 and running this code with Vitest - hence the ESM import.

import { Table, WriterPropertiesBuilder, Compression, writeParquet } from 'parquet-wasm/esm'
import initWasm from 'parquet-wasm/esm'

await initWasm()

Recieved error:

TypeError: fetch failed
Caused by: Error: not implemented... yet...

I think this means you need to either provide a polyfill for fetch, or, probably more simply you should import from the parquet-wasm/node export.
