Package description
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.
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);
});Similar to @aws-sdk/middleware-host-header, @aws-sdk/middleware-logger is also a middleware for the AWS SDK for JavaScript (v3) but focuses on logging requests and responses. While host-header middleware ensures the correct host header is set for service requests, the logger middleware provides insights into the request lifecycle, making it easier to debug and monitor AWS SDK operations.
Another middleware in the AWS SDK for JavaScript (v3), @aws-sdk/middleware-retry, provides automatic retry functionality for requests that fail due to transient errors. Unlike @aws-sdk/middleware-host-header, which ensures the correct host header, the retry middleware automatically retries requests based on predefined policies and strategies, helping to improve the robustness of applications interacting with AWS services.
