q - npm Package Versions
Changelog
0.3.0 - BACKWARD-INCOMPATIBLE
- The
postmethod has been reverted to its original signature, as provided in Tyler Close'sref_sendAPI. That is,postaccepts two arguments, the second of which is an arbitrary object, but usually invocation arguments as anArray. To provide variadic arguments topost, there is a newinvokefunction that posts the variadic arguments to the value given in the first argument. - The
definedmethod has been moved fromqtoq/utilsince it gets no use in practice but is still theoretically useful. - The
Promiseconstructor has been renamed tomakePromiseto be consistent with the convention that functions that do not require thenewkeyword to be used as constructors have camelCase names. - The
isResolvedfunction has been renamed toisFulfilled. There is a newisResolvedfunction that indicates whether a value is not a promise or, if it is a promise, whether it has been either fulfilled or rejected. The code has been revised to reflect this nuance in terminology.
Changelog
0.2.9
- The future-compatible
invokemethod has been added, to replacepost, sincepostwill become backward- incompatible in the next major release. - Exceptions thrown in the callbacks of a
whencall are now emitted to Node's"uncaughtException"processevent in addition to being returned as a rejection reason.
Changelog
0.2.8
- Exceptions thrown in the callbacks of a
whencall are now consumed, warned, and transformed into rejections of the promise returned bywhen.
Changelog
0.2.7
- Fixed a minor bug in thenable assimilation, regressed because of the change in the forwarding protocol.
- Fixed behavior of "q/util"
deepmethod on dates and other primitives. Github issue #11.
Changelog
0.2.6
- Thenables (objects with a "then" method) are accepted and provided, bringing this implementation of Q into conformance with Promises/A, B, and D.
- Added
makePromise, to replace thePromisefunction eventually. - Rejections are now also duck-typed. A rejection is a promise with a valueOf method that returns a rejection descriptor. A rejection descriptor has a "promiseRejected" property equal to "true" and a "reason" property corresponding to the rejection reason.
- Altered the
makePromiseAPI such that thefallbackmethod no longer receives a superfluousresolvedmethod after theoperator. The fallback method is responsible only for returning a resolution. This breaks an undocumented API, so third-party API's depending on the previous undocumented behavior may break.
Changelog
0.2.5
- Changed promises into a duck-type such that multiple
instances of the Q module can exchange promise objects.
A promise is now defined as "an object that implements the
promiseSend(op, resolved, ...)method andvalueOf". - Exceptions in promises are now captured and returned as rejections.
Changelog
0.2.4
- Fixed bug in
refthat preventeddelmessages from being received (gozala) - Fixed a conflict with FireFox 4; constructor property is now read-only.
Changelog
0.2.1
- The
resolveandrejectmethods ofdeferobjects now return the resolution promise for convenience. - Added
q/util, which providesstep,delay,shallow,deep, and three reduction orders. - Added
q/queuemodule for a promiseQueue. - Added
q-commto the list of compatible libraries. - Deprecated
definedfromq, with intent to move it toq/util.
