  • ES6 Promises in Depth
  • An Incremental Tutorial on Promises - An FAQ styled tutorial for beginners.
  • Promise Fun - @sindresorhus's notes, patterns, and solutions to common Promise problems
  • You're Missing the Point of Promises - Promises are much more than callback aggregation, and that jQuery's implementation (prior to 3.0) isn't enough.
  • We have a problem with promises - "Many of us are using promises without really understanding them."
  • Promise anti-patterns - Common misuses and how to avoid them.
  • Promise anti-patterns (2) - Another set of promises anti-patterns
  • Promise Ponderings, (Anti-)Patterns, and Apologies - Promise behaviour demonstrated and explained by common questions and their answers.
  • Javascript Promises...In Wicked Detail - Recreate the promise implementation
  • Writing Promise-Using Specifications - "This document gives guidance on how to write specifications that create, accept, or manipulate promises"
  • Async functions - making promises friendly
  • Promises/A+ specification
  • caniuse promises
  • Fates and States - Quick definitions of possible states.
  • Promisees - Promise visualization playground for the adventurous.
  • pinkie - Ponyfill. Node-oriented, but [browserifyable](https://github.com/substack/node-browserify). *Extremely* small implementation.
  • native-promise-only - Polyfill. Browser and node-compatible.
  • es6-promise - Opt-in polyfill. A strict-spec subset of rsvp.js.
  • lie - Small, browserifyable with an opt-in polyfill.
  • bluebird - Fully featured, extremely performant. Long stack traces & generator/coroutine support.
  • creed - Hyper performant & full featured like Bluebird, but FP-oriented. Coroutines, generators, promises, ES2015 iterables, & fantasy-land spec.
  • rsvp.js - Lightweight with a few extras. Compatible down to IE6!
  • Q - One of the original implementations. Long stack traces and other goodies.
  • then/promise - Small with `nodeify`, `denodify` and `done()` additions.
  • when.js - Packed with control flow, functional, and utility methods.
  • native-or-bluebird - Helps transition to completely native.
  • pinkie-promise - Use native, or fall back to `pinkie`. Great for node library authors.
  • any-promise - Loads the first available implementation. Safe for browserify.
  • delay - Delay a promise a specified amount of time.
  • pify - Promisify ("denodify") a callback-style function.
  • loud-rejection - Make unhandled promise rejections fail loudly instead of the default silent fail.
  • hard-rejection - Make unhandled promise rejections fail hard right away instead of the default silent fail
  • p-queue - Promise queue with concurrency control
  • p-break - Break out of a promise chain
  • p-lazy - Create a lazy promise that defers execution until `.then()` or `.catch()` is called
  • p-defer - Create a deferred promise
  • p-if - Conditional promise chains
  • p-tap - Tap into a promise chain without affecting its value or state
  • p-map - Map over promises concurrently
  • p-all - Run promise-returning & async functions concurrently with optional limited concurrency
  • p-limit - Run multiple promise-returning & async functions with limited concurrency
  • p-times - Run promise-returning & async functions a specific number of times concurrently
  • p-catch-if - Conditional promise catch handler
  • p-time - Measure the time a promise takes to resolve
  • p-log - Log the value/error of a promise
  • p-filter - Filter promises concurrently
  • p-settle - Settle promises concurrently and get their fulfillment value or rejection reason
  • p-memoize - Memoize promise-returning & async functions
  • p-whilst - Calls a function repeatedly while a condition returns true and then resolves the promise
  • p-throttle - Throttle promise-returning & async functions
  • p-debounce - Debounce promise-returning & async functions
  • p-retry - Retry a promise-returning or async function
  • p-wait-for - Wait for a condition to be true
  • p-timeout - Timeout a promise after a specified amount of time
  • p-race - A better `Promise.race()`
  • p-try - `Promise#try()` ponyfill - Starts a promise chain
  • p-finally - `Promise#finally()` ponyfill - Invoked when the promise is settled regardless of outcome
  • p-any - Wait for any promise to be fulfilled
  • p-some - Wait for a specified number of promises to be fulfilled
  • p-pipe - Compose promise-returning & async functions into a reusable pipeline
  • p-each-series - Iterate over promises serially
  • p-map-series - Map over promises serially
  • p-reduce - Reduce a list of values using promises into a promise for a value
  • p-props - Like `Promise.all()` but for `Map` and `Object`
  • promise-method - Standalone `bluebird.method`. Turn a synchronously-returning method into a promise-returning one.
  • is-promise - Determine if something looks like a Promise.
  • sprom - Resolve when a stream ends. Optional buffering (be careful with this!)
  • task.js - Write async functions in a blocking style using promises and generators. Like `bluebird.coroutine`.
  • co - Like `task.js` and `bluebird.coroutine`, but supports thunks too.
  • lie-fs - Promise wrappers for Node's FS API.
  • promise-do-until - Calls a function repeatedly until a condition returns true and then resolves the promise.
  • promise-do-whilst - Calls a function repeatedly while a condition returns true and then resolves the promise.
