ReferenceError: process is not defined

// package.json
 "dependencies": {
    "@duckdb/node-api": "^1.1.3-alpha.7",
    "@duckdb/node-bindings-darwin-arm64": "^1.1.3-alpha.7",
}

// config.ts
import { DuckDBInstance } from '@duckdb/node-api';

let db: DuckDBInstance | null = null;

export const initDB = async () => {
  if (db) {
    return db;
  }
  db = await DuckDBInstance.create();
  return db;
};

Simply importing this from another file will result in an error.

+page.svelte
import { initDB } from '$lib/duckdb/config.js';

I also get this error when I put in code to attach a CSV file from https://github.com/duckdb-wasm-examples/sveltekit-typescript.

Can you say more about what environment you're running the above code in?

Since you're using Svelte, a framework for frontend web applications, it seems likely you're trying to run this code in a browser environment. That isn't expected to work. This is a Node package, so it will only run in a Node environment. For running DuckDB in the browser, try DuckDB Wasm.

OK. I will test it with DuckDB Wasm.
