Modules

Bluebird

Provides classes for working with the bluebird library (http://bluebirdjs.com).

PromiseFlow

This module defines how data-flow propagates into and out of a Promise. The data-flow is based on pseudo-properties rather than tainting the Promise object (which is what PromiseTaintStep does).

PromiseTypeTracking

A module for supporting promises in type-tracking predicates. The PromiseTypeTracking::promiseStep predicate is used for type tracking in and out of promises, and is included in the standard type-tracking steps (SourceNode::track). The TypeTracker::startInPromise() predicate can be used to initiate a type-tracker where the tracked value is a promise.

Promises

Common predicates shared between type-tracking and data-flow for promises.

Promisify

Provides classes modeling libraries implementing promisify functions. That is, functions that convert callback style functions to functions that return a promise.

Q

Provides classes for working with the q library (https://github.com/kriskowal/q) and the compatible kew library (https://github.com/Medium/kew).
