The abort-controller package provides a standard AbortController and AbortSignal implementation, enabling cancellation capabilities for asynchronous operations like fetch requests, streams, and more. Crucially, it brings the Abort API to environments lacking native support, ensuring consistent behavior across browsers and Node.js. This allows you to gracefully terminate long-running processes and prevent unnecessary resource consumption when a request is no longer needed, greatly improving application performance and responsiveness. By using this package, developers can implement standardized abort handling in their code.
The abort-controller npm package had initial releases in late 2017, followed by sporadic updates through early 2019, including version jumps. Since March 2019, there have been no new releases. The package appears to be inactive as of September 11, 2025, with no updates in over six years.
Abort-controller downloads surged from March 2024 (44.8M) peaking in July 2025 (109.5M). A general upward trend is evident, with significant growth throughout 2024 and the first half of 2025. September 2025 shows a substantial drop, but represents incomplete monthly data.
