AWS SDK for JavaScript S3 Client for Node.js, Browser and React Native
AWS SDK for JavaScript S3 Client for Node.js, Browser and React Native.
To install this package, use the CLI of your favorite package manager:
npm install @aws-sdk/client-s3yarn add @aws-sdk/client-s3pnpm add @aws-sdk/client-s3The AWS SDK is modulized by clients and commands.
To send a request, you only need to import the S3Client and
the commands you need, for example ListBucketsCommand:
// ES5 example
const { S3Client, ListBucketsCommand } = require("@aws-sdk/client-s3");
// ES6+ example
import { S3Client, ListBucketsCommand } from "@aws-sdk/client-s3";
To send a request:
send operation on the client, providing the command object as input.const client = new S3Client({ region: "REGION" });
const params = { /** input parameters */ };
const command = new ListBucketsCommand(params);
We recommend using the 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.
}
You can also use Promise chaining.
client
.send(command)
.then((data) => {
// process data.
})
.catch((error) => {
// error handling.
})
.finally(() => {
// finally.
});
The aggregated client class is exported from the same package, but without the "Client" suffix.
S3 extends S3Client and additionally supports all operations, waiters, and paginators as methods.
This style may be familiar to you from the AWS SDK for JavaScript v2.
If you are bundling the AWS SDK, we recommend using only the bare-bones client (S3Client).
More details are in the blog post on
modular packages in AWS SDK for JavaScript.
import { S3 } from "@aws-sdk/client-s3";
const client = new S3({ region: "REGION" });
// async/await.
try {
const data = await client.listBuckets(params);
// process data.
} catch (error) {
// error handling.
}
// Promises.
client
.listBuckets(params)
.then((data) => {
// process data.
})
.catch((error) => {
// error handling.
});
// callbacks (not recommended).
client.listBuckets(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;
* }
*/
}

The 'aws-sdk' package is the predecessor of '@aws-sdk/client-s3' and provides a comprehensive AWS SDK for JavaScript. It includes support for S3 and other AWS services. Compared to '@aws-sdk/client-s3', it is less modular and typically larger in size, which might affect bundle sizes in frontend applications.
The 's3' package is a high-level client for Amazon S3 with a more simplified API. It provides easy-to-use methods for common S3 operations. It is not an official AWS SDK, and it may not support all S3 features or the latest AWS updates as '@aws-sdk/client-s3' does.
