Package description

What is @aws-sdk/middleware-apply-body-checksum?

@aws-sdk/middleware-apply-body-checksum is a middleware package for the AWS SDK for JavaScript. It is used to automatically apply checksums to the body of requests, ensuring data integrity during transmission.

What are @aws-sdk/middleware-apply-body-checksum's main functionalities?

Apply Checksum to Request Body

This feature demonstrates how to apply a checksum to the body of a request using the @aws-sdk/middleware-apply-body-checksum package. The middleware is added to the S3 client's middleware stack, ensuring that the body of the PutObjectCommand request is checksummed before being sent.

const { S3Client, PutObjectCommand } = require('@aws-sdk/client-s3');
const { applyBodyChecksumMiddleware } = require('@aws-sdk/middleware-apply-body-checksum');

const client = new S3Client({ region: 'us-west-2' });
client.middlewareStack.add(applyBodyChecksumMiddleware(), {
  step: 'build',
  priority: 'high',
});

const command = new PutObjectCommand({
  Bucket: 'example-bucket',
  Key: 'example-object',
  Body: 'Hello, world!',
});

client.send(command).then((response) => {
  console.log('Success', response);
}).catch((error) => {
  console.error('Error', error);
});
