@aws-sdk/fetch-http-handler

What is @aws-sdk/fetch-http-handler?

The @aws-sdk/fetch-http-handler npm package is a module that provides a way to send HTTP requests using the Fetch API. It is part of the AWS SDK for JavaScript (v3) and is used internally by the SDK to send requests to AWS services. It can be used directly to make HTTP requests in environments where the Fetch API is available, such as modern web browsers and Node.js (with a polyfill).

What are @aws-sdk/fetch-http-handler's main functionalities?

Sending HTTP requests

This feature allows you to send HTTP requests using the Fetch API. The code sample demonstrates how to create a new instance of FetchHttpHandler and use it to send a GET request to a specified URL.

{"import { FetchHttpHandler } from '@aws-sdk/fetch-http-handler';
const httpHandler = new FetchHttpHandler();
const requestOptions = {
  method: 'GET',
  headers: {
    'Content-Type': 'application/json'
  }
};
httpHandler.handle({
  request: new Request('https://example.com', requestOptions),
  input: {},
  abortSignal: null
}).then(response => {
  // Handle the response
});"}

Other packages similar to @aws-sdk/fetch-http-handler

axios

Axios is a popular HTTP client for the browser and Node.js. It provides a promise-based API and is known for its ease of use. Unlike @aws-sdk/fetch-http-handler, Axios is not specific to AWS and can be used for any HTTP requests. It also has built-in support for request and response interceptors, which can be useful for adding custom logic to the request/response cycle.

node-fetch

node-fetch is a lightweight module that brings the Fetch API to Node.js. It is similar to @aws-sdk/fetch-http-handler in that it allows you to make HTTP requests using the Fetch API, but it is not tied to the AWS SDK and can be used independently for any HTTP requests in Node.js environments.

got

Got is a human-friendly and powerful HTTP request library for Node.js. It provides a simpler and more intuitive API compared to the native http module in Node.js. Got supports streams, advanced timeout handling, and custom instances. It is not specific to AWS and offers more extensive features for general HTTP requests than @aws-sdk/fetch-http-handler.
