Using 'adapt' from @google-cloud/bigquery-storage

Question

I'm trying to use @google-cloud/bigquery-storage and it seems I can't get adapt. This is what I'm trying to do.

const { v1, adapt } = require('@google-cloud/bigquery-storage');
const { BigQueryWriteClient } = v1;
const { BigQuery } = require('@google-cloud/bigquery');

    async function BQStorageWrite() {
    
        const bigquery = new BigQuery({ projectId: bqProjectId });
        const dataset = bigquery.dataset(bqDataSetId);
        const table = await dataset.table(bqTableId);
        const [metadata] = await table.getMetadata();
    
        console.log('adapt ' + adapt); // adapt undefined
        console.log('v1 ' + v1); // v1 [object Object]
    
        const storageSchema = adapt.convertBigQuerySchemaToStorageTableSchema(
              metadata.schema
        );

       //Writing data to a BQ Table
    }

adapt is undefined as per the console log, hence I get an error saying 'TypeError: Cannot read properties of undefined (reading 'convertBigQuerySchemaToStorageTableSchema')'

Am I missing something obvious here? What is the correct way to get this imported? Thank you.

Answer 1

@DbxD, As you have mentioned in the comment.

adapt is not released into the library yet till the latest version @google-cloud/bigquery-storage v 3.3.0. Hence we can't import it. It will be available in the next library release.
