Q is a JavaScript promise library implementing the Promises/A+ specification for asynchronous flow control in Node.js and browsers. It predates native ES6 promises and is now in maintenance mode, with the README recommending native Promise instead.
Use cases
- flatten callback pyramids in async javascript code
- manage promise chains with error propagation
- convert node.js callback functions to promises
- support promises in environments without native Promise
- learn how promises work historically
When to choose
- maintaining a legacy codebase already using Q
- targeting very old JavaScript environments without native promises
- studying promise library design and history
When to avoid
- starting a new project - use native JavaScript promises
- you need maximum performance or modern tooling support
- you need async/await with native promise integration
