AWS SDK for JavaScript S3 Client for Node.js, Browser and React Native.

March 7, 2026 - Bare-bones clients/commands: This refers to a modular way of consuming individual operations on JS SDK clients. It results in less code being imported and thus more performant. It is otherwise equivalent to the aggregated clients/commands. // this imports a bare-bones version of S3 that exposes the .send operation import { S3Client } from "@aws-sdk/client-s3" // this imports just the getObject operation from S3 import { GetObjectCommand } from "@aws-sdk/client-s3" //usage const bareBonesS3 = new S3Client({...}); await bareBonesS3.send(new GetObjectCommand({...}));

August 13, 2023 - 1) Client Region And Update Client From reading other issues (some examples: #1802, #1807, #1845, #3469) I know that in the AWS SDK V3, we need to pass the region of the bucket the client will work on. I thought about wrapping the commands with a "guess" of the region and then handling the error and taking the region from it (for example, when using listObjects with another region we get AuthorizationHeaderMalformed and have the region in the error). But I don't see we have s3.config.update (s3 is the variable that holds the instance of S3).

import {S3Client, CreateMultipartUploadCommand, UploadPartCommand} from '@aws-sdk/client-s3'; import {Upload} from "@aws-sdk/lib-storage"; const s3Mock = mockClient(S3Client); // for big files upload: s3Mock.on(CreateMultipartUploadCommand).resolves({UploadId: '1'}); s3Mock.on(UploadPartCommand).resolves({ETag: '1'}); // for small files upload: s3ClientMock.on(PutObjectCommand).callsFake(async (input, getClient) => { getClient().config.endpoint = () => ({hostname: ""}) as any; return {}; }); const s3Upload = new Upload({ client: new S3Client({}), params: { Bucket: 'mock', Key: 'test', Body: 'x'.repeat(6 * 1024 * 1024), // 6 MB }, }); s3Upload.on('httpUploadProgress', (progress) => { console.log(progress); }); await s3Upload.done();
