Quickstart

Before you begin

1. Select or create a Cloud Platform project.

   Go to the projects page

2. Enable billing for your project.

   Enable billing

3. Enable the Cloud Bigtable and Cloud Bigtable Admin APIs.

   Enable the APIs

4. Set up authentication with a service account so you can access the API from your local workstation.

Installing the client library

npm install --save @google-cloud/bigtable

Using the client library

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

// The name of the Cloud Bigtable instance
const INSTANCE_NAME = 'my-bigtable-instance';
// The name of the Cloud Bigtable table
const TABLE_NAME = 'my-table';

(async () => {
  try {
    // Creates a Bigtable client
    const bigtable = new Bigtable();

    // Connect to an existing instance:my-bigtable-instance
    const instance = bigtable.instance(INSTANCE_NAME);

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

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

    // Print the row key and data (column value, labels, timestamp)
    console.log(
      `Row key: ${singleRow.id}\nData: ${JSON.stringify(
        singleRow.data,
        null,
        4
      )}`
    );
  } catch (err) {
    // Handle error performing the read operation
    console.error(`Error reading row r1:`, err);
  }
})();

Versioning

This library follows Semantic Versioning.

This library is considered to be in beta. This means it is expected to be mostly stable while we work toward a general availability release; however, complete stability is not guaranteed. We will address issues and requests against beta libraries with a high priority.
