pinkie
A minimal ES2015 Promise implementation for Node.js, focusing on spec compliance over browser compatibility.
What is pinkie?
Pinkie is a minimal ES2015 Promise implementation for Node.js that serves as an exact polyfill of the Promise specification. It focuses on providing spec-compliant Promise functionality without the bloat of browser compatibility layers, making it lightweight and efficient for server-side use.
Node.js developers who need a spec-compliant Promise polyfill without unnecessary browser compatibility features, particularly those building server-side applications or tools.
Developers choose Pinkie for its minimalism and strict adherence to the ES2015 Promise spec, offering a lightweight alternative to larger Promise libraries that include extensive browser support code.
Overview

Use Cases
Best For
- Adding Promise support to Node.js projects without native ES2015 support
- Building lightweight Node.js tools or libraries that require Promises
- Ensuring spec-compliant Promise behavior in server-side applications
- Reducing dependency size by avoiding bloated Promise polyfills
- Polyfilling Promises in environments where browser compatibility is not needed
- Educational purposes to understand ES2015 Promise implementation
Not Ideal For
- Browser-first applications without a bundler like Browserify
- Projects requiring advanced Promise features like cancellation or progress tracking
- Modern Node.js environments with native Promise support already available
Pros & Cons
Pros
Pinkie avoids unnecessary browser compatibility code, keeping the implementation small and efficient for server-side use, as emphasized in the README.
It provides an exact polyfill of the Promise specification, ensuring reliable and standard behavior in Node.js environments.
Includes polyfills for Node.js rejection events, making it tailored for server-side applications and enhancing error handling.
Can be bundled for browser use via Browserify, offering flexibility for projects that need cross-platform compatibility.
Cons
Lacks built-in compatibility for browsers, requiring additional tooling like Browserify, which adds complexity for web-focused projects.
Strictly adheres to the ES2015 spec, missing advanced features like cancellation or utility methods found in libraries like Bluebird.
In modern Node.js versions that support native Promises, Pinkie adds unnecessary dependency overhead without significant benefits.
