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. If you are using an end-of-life version of Node.js, we recommend that you update as soon as possible to an actively supported LTS version.

Google's client libraries support legacy versions of Node.js runtimes on a best-efforts basis with the following warnings:

Legacy versions are not tested in continuous integration.
Some security patches and features cannot be backported.
Dependencies cannot be kept up-to-date.

Client libraries targeting some end-of-life versions of Node.js are available, and can be installed through npm dist-tags. The dist-tags follow the naming convention legacy-(version). For example, npm install @google-cloud/bigtable@legacy-8 installs client libraries for versions compatible with Node.js 8.

Versioning

This library follows Semantic Versioning.

This library is considered to be 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 stable libraries are addressed with the highest priority.
