# [Cloud Spanner: Node.js Client](https://github.com/googleapis/nodejs-spanner)

[![release level](https://img.shields.io/badge/release%20level-stable-brightgreen.svg?style=flat)](https://cloud.google.com/terms/launch-stages)

[![npm version](https://img.shields.io/npm/v/@google-cloud/spanner.svg)](https://www.npmjs.org/package/@google-cloud/spanner)

[Cloud Spanner](https://cloud.google.com/spanner/docs/) 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](https://github.com/googleapis/nodejs-spanner/blob/main/CHANGELOG.md).

## Quickstart

### Before you begin

1.  [Select or create a Cloud Platform project][projects].

1.  [Enable billing for your project][billing].

1.  [Enable the Cloud Spanner API][enable_api].

1.  [Set up authentication][auth] so you can access the

    API from your local workstation.

### Installing the client library

```bash

npm install @google-cloud/spanner

```

### Using the client library

```javascript

// 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));

```

## Samples

Samples are in the [`samples/`](https://github.com/googleapis/nodejs-spanner/tree/main/samples) directory. Each sample's `README.md` has instructions for running its sample.

also contains samples.

## Supported Node.js Versions

Our client libraries follow the [Node.js release schedule](https://github.com/nodejs/release#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](https://docs.npmjs.com/cli/dist-tag).

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](http://semver.org/).

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.
