@aws-sdk/abort-controller

What is @aws-sdk/abort-controller?

The @aws-sdk/abort-controller npm package provides a mechanism to abort one or more Web requests before they have completed. It is primarily used to enhance the management of API requests, particularly in environments where network requests can hang or need to be manually terminated to manage resources effectively.

What are @aws-sdk/abort-controller's main functionalities?

Abort HTTP requests

This code sample demonstrates how to use the AbortController to abort an HTTP fetch request. The 'signal' is passed to the fetch request, and the request can be aborted by calling 'controller.abort()'.

const { AbortController } = require('@aws-sdk/abort-controller');
const controller = new AbortController();
const signal = controller.signal;

fetch('https://api.example.com/data', { signal })
  .then(response => response.json())
  .catch(err => {
    if (err.name === 'AbortError') {
      console.log('Fetch aborted');
    } else {
      console.error('Fetch error:', err);
    }
  });

// Abort the request
controller.abort();

Other packages similar to @aws-sdk/abort-controller

abort-controller

The 'abort-controller' package provides a similar functionality to @aws-sdk/abort-controller by implementing the AbortController interface to abort fetch requests. It is widely used for managing fetch-based network requests and is compatible with the standard web API, making it a direct alternative.

node-abort-controller

The 'node-abort-controller' package is another alternative that implements the AbortController API for Node.js environments. It allows developers to abort asynchronous tasks and HTTP requests. It is similar to @aws-sdk/abort-controller but is specifically tailored for Node.js, unlike the more general-purpose @aws-sdk/abort-controller which is designed with AWS SDK integrations in mind.
