Real Cancellable Promise

`real-cancellable-promise` is a robust and lightweight library offering a cancellable Promise implementation for JavaScript and TypeScript. Unlike many other approaches that merely prevent callbacks from executing, this library focuses on propagating cancellation signals to the underlying asynchronous operations, such as network requests made with `fetch`, `axios`, or `jQuery.ajax`, thereby releasing resources and truly aborting tasks. It boasts zero dependencies and a minimal footprint, under 1 kB minified and gzipped. The current stable version is 1.2.3, with ongoing active maintenance reflected in its consistent bug fix releases. Key differentiators include its explicit support for 'real' cancellation and its compatibility with popular ecosystems like React (solving issues like `setState` after unmount and handling variable query parameters) and `react-query`'s cancellation features out-of-the-box. It supports modern browsers (excluding Internet Explorer) and Node.js 14+ (with `AbortController` functionality requiring Node 15+).
