if (typeof globalThis.__dirname === 'undefined') {
  globalThis.__dirname = import.meta.dirname
}

const tmpDir = path.join(__dirname, 'tmp');

// Download jsapi from a Deephaven server
const dhc = await loadDhModules({
  serverUrl: new URL('http://localhost:10000'),
  storageDir: tmpDir,
  targetModuleType: 'esm', // set to `cjs` to download as a CommonJS module
});

const client = new dhc.CoreClient(serverUrl.href, {
  // Enable http2 transport (this is optional but recommended)
  transportFactory: NodeHttp2gRPCTransport.factory,
})

await client.login({

const cn = await client.getAsIdeConnection()
