Send XML data to Google BigQuery Using Node.js

To send XML data to Google BigQuery using Node.js, you will need to use the BigQuery API.

Here’s an example of how you can do this:

1. First, you will need to set up a project in the Google Cloud Console and enable the BigQuery API.
2. Install the Google Cloud client library for Node.js by running the following command:

npm install @google-cloud/bigquery

3. Import the BigQuery client and authenticate your application by creating a JSON key file and setting the GOOGLE_APPLICATION_CREDENTIALS environment variable:

const {BigQuery} = require('@google-cloud/bigquery');
const bigquery = new BigQuery();

4. Next, you can create a dataset and table in BigQuery to hold the XML data. You can do this using the createDataset and createTable methods of the BigQuery client:

async function createDatasetAndTable() {
  // Create a dataset
  const dataset = bigquery.dataset('xml_dataset');
  await dataset.create();

  // Create a table in the dataset
  const table = dataset.table('xml_table');
  await table.create({
    schema: 'xml:string',
  });
}

5. To insert the XML data into the table, you can use the insert method of the Table object:

async function insertXMLData(xml) {
  const rows = [{xml}];
  const options = {
    raw: true,
  };

  const [insertErrors] = await table.insert(rows, options);
  if (insertErrors) {
    insertErrors.forEach(console.error);
  }
}

That’s it! You should now be able to send XML data to Google BigQuery using Node.js and the BigQuery API.
