Services or capabilities described in Amazon Web Services documentation might vary by Region. To see the differences applicable to the China Regions, see Getting Started with Amazon Web Services in China (PDF).

The Amazon SDK for JavaScript V3 API Reference Guide describes in detail all the API operations for the Amazon SDK for JavaScript version 3 (V3).

Amazon Redshift examples using SDK for JavaScript (v3)

The following code examples show you how to perform actions and implement common scenarios by using the Amazon SDK for JavaScript (v3) with Amazon Redshift.

Actions are code excerpts from larger programs and must be run in context. While actions show you how to call individual service functions, you can see actions in context in their related scenarios and cross-service examples.

Scenarios are code examples that show you how to accomplish a specific task by calling multiple functions within the same service.

Each example includes a link to GitHub, where you can find instructions on how to set up and run the code in context.

The following code example shows how to use CreateCluster.

SDK for JavaScript (v3)
Note

There's more on GitHub. Find the complete example and learn how to set up and run in the Amazon Code Examples Repository.

Create the client.

const { RedshiftClient } = require("@aws-sdk/client-redshift");
// Set the AWS Region.
const REGION = "REGION";
//Set the Redshift Service Object
const redshiftClient = new RedshiftClient({ region: REGION });
export { redshiftClient };

Create the cluster.

// Import required AWS SDK clients and commands for Node.js
import { CreateClusterCommand } from "@aws-sdk/client-redshift";
import { redshiftClient } from "./libs/redshiftClient.js";

const params = {
  ClusterIdentifier: "CLUSTER_NAME", // Required
  NodeType: "NODE_TYPE", //Required
  MasterUsername: "MASTER_USER_NAME", // Required - must be lowercase
  MasterUserPassword: "MASTER_USER_PASSWORD", // Required - must contain at least one uppercase letter, and one number
  ClusterType: "CLUSTER_TYPE", // Required
  IAMRoleARN: "IAM_ROLE_ARN", // Optional - the ARN of an IAM role with permissions your cluster needs to access other AWS services on your behalf, such as Amazon S3.
  ClusterSubnetGroupName: "CLUSTER_SUBNET_GROUPNAME", //Optional - the name of a cluster subnet group to be associated with this cluster. Defaults to 'default' if not specified.
  DBName: "DATABASE_NAME", // Optional - defaults to 'dev' if not specified
  Port: "PORT_NUMBER", // Optional - defaults to '5439' if not specified
};

const run = async () => {
  try {
    const data = await redshiftClient.send(new CreateClusterCommand(params));
    console.log(
      "Cluster " + data.Cluster.ClusterIdentifier + " successfully created",
    );
    return data; // For unit tests.
  } catch (err) {
    console.log("Error", err);
  }
};
run();

Create the client.

const { RedshiftClient } = require("@aws-sdk/client-redshift");
// Set the AWS Region.
const REGION = "REGION";
//Set the Redshift Service Object
const redshiftClient = new RedshiftClient({ region: REGION });
export { redshiftClient };

Create the cluster.

// Import required AWS SDK clients and commands for Node.js
import { DeleteClusterCommand } from "@aws-sdk/client-redshift";
import { redshiftClient } from "./libs/redshiftClient.js";

const params = {
  ClusterIdentifier: "CLUSTER_NAME",
  SkipFinalClusterSnapshot: false,
  FinalClusterSnapshotIdentifier: "CLUSTER_SNAPSHOT_ID",
};

const run = async () => {
  try {
    const data = await redshiftClient.send(new DeleteClusterCommand(params));
    console.log("Success, cluster deleted. ", data);
    return data; // For unit tests.
  } catch (err) {
    console.log("Error", err);
  }
};

Create the client.

const { RedshiftClient } = require("@aws-sdk/client-redshift");
// Set the AWS Region.
const REGION = "REGION";
//Set the Redshift Service Object
const redshiftClient = new RedshiftClient({ region: REGION });
export { redshiftClient };

Describe your clusters.

// Import required AWS SDK clients and commands for Node.js
import { DescribeClustersCommand } from "@aws-sdk/client-redshift";
import { redshiftClient } from "./libs/redshiftClient.js";

const params = {
  ClusterIdentifier: "CLUSTER_NAME",
