AWS SDK for JavaScript Cloudformation Client for Node.js, Browser and React Native
The @aws-sdk/client-cloudformation npm package is a client library for AWS CloudFormation service. It allows developers to interact with the AWS CloudFormation service programmatically, enabling them to create, manage, and deploy AWS CloudFormation stacks and resources directly from their JavaScript or TypeScript applications.
Managing Stacks
This feature allows you to manage AWS CloudFormation stacks, including creating, updating, and deleting stacks.
const { CloudFormationClient, CreateStackCommand } = require('@aws-sdk/client-cloudformation');
const client = new CloudFormationClient({ region: 'us-west-2' });
const createStackParams = {
StackName: 'MyStack',
TemplateBody: 'JSON or YAML template',
};
const command = new CreateStackCommand(createStackParams);
client.send(command).then((data) => {
console.log('Stack creation initiated:', data);
}).catch((error) => {
console.error('Error creating stack:', error);
});Describing Stack Resources
This feature allows you to retrieve information about the resources within a specific stack.
const { CloudFormationClient, DescribeStackResourcesCommand } = require('@aws-sdk/client-cloudformation');
const client = new CloudFormationClient({ region: 'us-west-2' });
const describeStackResourcesParams = {
StackName: 'MyStack'
};
const command = new DescribeStackResourcesCommand(describeStackResourcesParams);
client.send(command).then((data) => {
console.log('Stack resources:', data);
}).catch((error) => {
console.error('Error describing stack resources:', error);
});Listing Stacks
This feature allows you to list all stacks and their statuses in your AWS account.
const { CloudFormationClient, ListStacksCommand } = require('@aws-sdk/client-cloudformation');
const client = new CloudFormationClient({ region: 'us-west-2' });
const command = new ListStacksCommand({});
client.send(command).then((data) => {
console.log('List of stacks:', data);
}).catch((error) => {
console.error('Error listing stacks:', error);
});The 'aws-sdk' package is the predecessor of the '@aws-sdk/client-cloudformation' and provides a comprehensive AWS SDK for JavaScript. It supports CloudFormation operations but is not modular, meaning it includes the entire AWS SDK rather than just the CloudFormation service.
The 'serverless' package is a framework for building serverless applications using AWS Lambda and other cloud providers. It includes functionality for managing infrastructure as code, similar to CloudFormation, but it is more opinionated and provides a higher-level abstraction for deploying serverless applications.
The 'pulumi' package is a modern infrastructure as code SDK that allows you to define cloud resources using general-purpose programming languages. It is similar to CloudFormation in that it manages cloud resources but offers a different approach by using familiar programming languages and real code to define infrastructure.

CloudFormation
CloudFormation allows you to create and manage Amazon Web Services infrastructure deployments predictably and repeatedly. You can use CloudFormation to leverage Amazon Web Services products, such as Amazon Elastic Compute Cloud, Amazon Elastic Block Store, Amazon Simple Notification Service, Elastic Load Balancing, and Amazon EC2 Auto Scaling to build highly reliable, highly scalable, cost-effective applications without creating or configuring the underlying Amazon Web Services infrastructure.
With CloudFormation, you declare all your resources and dependencies in a template file. The template defines a collection of resources as a single unit called a stack. CloudFormation creates and deletes all member resources of the stack together and manages all dependencies between the resources for you.
For more information about CloudFormation, see the CloudFormation product page.
CloudFormation makes use of other Amazon Web Services products. If you need additional technical information about a specific Amazon Web Services product, you can find the product's technical documentation at docs.aws.amazon.com.
To install this package, simply type add or install @aws-sdk/client-cloudformation using your favorite package manager:
npm install @aws-sdk/client-cloudformationyarn add @aws-sdk/client-cloudformationpnpm add @aws-sdk/client-cloudformationThe AWS SDK is modulized by clients and commands.
To send a request, you only need to import the CloudFormationClient and
the commands you need, for example ListExportsCommand:
// ES5 example
const { CloudFormationClient, ListExportsCommand } = require("@aws-sdk/client-cloudformation");
// ES6+ example
import { CloudFormationClient, ListExportsCommand } from "@aws-sdk/client-cloudformation";
To send a request, you:
send operation on client with command object as input.destroy() to close open connections.// a client can be shared by different commands.
const client = new CloudFormationClient({ region: "REGION" });
const params = {
/** input parameters */
};
const command = new ListExportsCommand(params);
We recommend using await operator to wait for the promise returned by send operation as follows:
// async/await.
try {
const data = await client.send(command);
// process data.
} catch (error) {
// error handling.
} finally {
// finally.
}
Async-await is clean, concise, intuitive, easy to debug and has better error handling as compared to using Promise chains or callbacks.
You can also use Promise chaining to execute send operation.
client.send(command).then(
(data) => {
// process data.
},
(error) => {
// error handling.
}
);
Promises can also be called using .catch() and .finally() as follows:
client
.send(command)
.then((data) => {
// process data.
})
.catch((error) => {
// error handling.
})
.finally(() => {
// finally.
});
We do not recommend using callbacks because of callback hell, but they are supported by the send operation.
// callbacks.
client.send(command, (err, data) => {
// process err and data.
});
The client can also send requests using v2 compatible style. However, it results in a bigger bundle size and may be dropped in next major version. More details in the blog post on modular packages in AWS SDK for JavaScript
import * as AWS from "@aws-sdk/client-cloudformation";
const client = new AWS.CloudFormation({ region: "REGION" });
// async/await.
try {
const data = await client.listExports(params);
// process data.
} catch (error) {
// error handling.
}
// Promises.
client
.listExports(params)
.then((data) => {
// process data.
})
.catch((error) => {
// error handling.
});
// callbacks.
client.listExports(params, (err, data) => {
// process err and data.
});
When the service returns an exception, the error will include the exception information, as well as response metadata (e.g. request id).
try {
const data = await client.send(command);
// process data.
} catch (error) {
const { requestId, cfId, extendedRequestId } = error.$metadata;
console.log({ requestId, cfId, extendedRequestId });
/**
* The keys within exceptions are also parsed.
* You can access them by specifying exception names:
* if (error.name === 'SomeServiceException') {
* const value = error.specialKeyInException;
* }
*/
}
