ES2015 Promise ponyfill that uses native Promise when available, otherwise falls back to the pinkie polyfill.
pinkie-promise is a Promise ponyfill for JavaScript that provides a consistent Promise implementation across different environments. It automatically uses the native ES2015 Promise when available, and falls back to the pinkie polyfill for older environments that lack Promise support. This ensures that Promise-based code works reliably whether running in modern browsers, Node.js versions with native Promise support, or legacy environments.
JavaScript developers building libraries, tools, or applications that need to work across different JavaScript environments including older browsers and Node.js versions without native Promise support.
Developers choose pinkie-promise because it provides a reliable, lightweight Promise implementation without modifying global objects unnecessarily. Its ponyfill approach makes it safer for use in libraries compared to polyfills that might conflict with other code, while still ensuring Promise functionality is available everywhere.
Promise ponyfill with pinkie
Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Exports the native ES2015 Promise when available, as stated in the README, ensuring optimal performance in compatible environments without manual checks.
Falls back to pinkie, a minimal Promise polyfill, keeping bundle size small for legacy support compared to heavier alternatives.
Provides a standard ES2015 Promise API, so developers can write Promise-based code that works uniformly across different JavaScript runtimes.
Doesn't pollute the global scope by default, making it safer for use in libraries and reducing the risk of conflicts with other code, as highlighted in the philosophy.
The pinkie polyfill may not include newer Promise methods introduced after ES2015, such as Promise.allSettled, limiting compatibility with modern JavaScript code.
Relies on the pinkie library, which might have slower update cycles or less active maintenance compared to broader polyfills like core-js, potentially missing bug fixes or optimizations.
Requires explicit import and usage in each module, unlike automated polyfill tools that inject globally, which can be cumbersome for large applications needing consistent Promise behavior.
