Cloud Spanner: Node.js Client
Cloud Spanner is a fully managed, mission-critical, relational database service that offers transactional consistency at global scale, schemas, SQL (ANSI 2011 with extensions), and automatic, synchronous replication for high availability.
A comprehensive list of changes in each version may be found in the CHANGELOG .

Quickstart
Before you begin
- Select or create a Cloud Platform project .
- Enable billing for your project .
- Enable the Cloud Spanner 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/spanner
Using the client library
// Imports the Google Cloud client library
const {Spanner} = require(' @google-cloud/spanner
');
// Creates a client
const spanner = new Spanner
({projectId});
// Gets a reference to a Cloud Spanner instance and database
const instance = spanner.instance(instanceId);
const database = instance.database(databaseId);
// The query to execute
const query = {
sql: 'SELECT 1',
};
// Execute a simple SQL statement
const [rows] = await database.run(query);
console.log(`Query: ${rows.length} found.`);
rows.forEach(row => console.log(row));

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/spanner@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 stablelibraries are addressed with the highest priority.
