Package description

What is @aws-sdk/middleware-host-header?

The @aws-sdk/middleware-host-header npm package is part of the AWS SDK for JavaScript (v3). It is a middleware that is used for setting the host header in the request. This is particularly useful when making HTTP requests to AWS services, ensuring that the host header matches the service endpoint. This can be critical for the proper routing and handling of requests within AWS's infrastructure.

What are @aws-sdk/middleware-host-header's main functionalities?

Setting Host Header

This code demonstrates how to add the hostHeaderMiddleware to an AWS SDK client instance. In this example, an S3 client is created, and the middleware is added to automatically set the host header when sending a PutObjectCommand. This ensures that the request is properly routed to the intended AWS service endpoint.

"use strict";
const { S3Client, PutObjectCommand } = require('@aws-sdk/client-s3');
const { hostHeaderMiddleware } = require('@aws-sdk/middleware-host-header');

const client = new S3Client({});
client.middlewareStack.add(hostHeaderMiddleware(), {
  step: 'build',
  name: 'hostHeaderMiddleware',
  tags: { SET_HOST_HEADER: true },
  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);
});
