Quickstart

Before you begin

Select or create a Cloud Platform project .
Enable billing for your project .
Enable the Cloud Bigtable API .
Set up authentication with a service account so you can access the API from your local workstation.

Installing the client library

 npm install @google-cloud/bigtable

Using the client library

 // Imports the Google Cloud client library
const {Bigtable} = require(' @google-cloud/bigtable 
');

const bigtable = new Bigtable 
();

async function quickstart() {
  // Connect to an existing instance:my-bigtable-instance
  const instance = bigtable.instance(INSTANCE_ID);

  // Connect to an existing table:my-table
  const table = instance.table(TABLE_ID);

  // Read a row from my-table using a row key
  const [singleRow] = await table.row('r1').get();

  // Print the row key and data (column value, labels, timestamp)
  const rowData = JSON.stringify(singleRow.data, null, 4);
  console.log(`Row key: ${singleRow.id}\nData: ${rowData}`);
}
quickstart();

Supported Node.js Versions

Our client libraries follow the Node.js release schedule . Libraries are compatible with all current active and maintenance versions of Node.js.

Client libraries targeting some end-of-life versions of Node.js are available, and can be installed via npm dist-tags . The dist-tags follow the naming convention legacy-(version) .

Legacy Node.js versions are supported as a best effort:

Legacy versions will not be tested in continuous integration.
Some security patches may not be able to be backported.
Dependencies will not be kept up-to-date, and features will not be backported.

Legacy tags available

legacy-8 : install client libraries from this dist-tag for versions compatible with Node.js 8.

Versioning

This library follows Semantic Versioning .

This library is considered to be General Availability (GA). This means it is stable; the code surface will not change in backwards-incompatible ways unless absolutely necessary (e.g. because of critical security issues) or with an extensive deprecation period. Issues and requests against GAlibraries are addressed with the highest priority.
