q - npm Package Versions
Changelog
0.6.0 - BACKWARD INCOMPATIBILITY
- WARNING: In practice, the implementation of
spyand the namefinwere useful. I've removed the oldfinimplementation and renamed/aliasedspy. - The "q" module now exports its
reffunction as a "Q" constructor, with module systems that support exports assignment including NodeJS, RequireJS, and when used as a<script>tag. Notably, strictly compliant CommonJS does not support this, but UncommonJS does. - Added
asyncdecorator for generators that use yield to "trampoline" promises. In engines that support generators (SpiderMonkey), this will greatly reduce the need for nested callbacks. - Made
whenchainable. - Made
allchainable.
Changelog
0.5.3
- Added
alland refactoredjoinandwaitto use it. All of these will now reject at the earliest rejection.
Changelog
0.5.1
- Made most Q API methods chainable on promise objects, and
turned the previous promise-methods of
join,wait, andreportinto Q API methods. - Added
applyandcallto the Q API, andapplyas a promise handler. - Added
fail,fin, andspyto Q and the promise prototype for convenience when observing rejection, fulfillment and rejection, or just observing without affecting the resolution. - Renamed
def(althoughdefremains shimmed until the next major release) tomaster. - Switched to using
MessageChannelfor next tick task enqueue in browsers that support it.
Changelog
0.5.0 - MINOR BACKWARD INCOMPATIBILITY
- Exceptions are no longer reported when consumed.
- Removed
errorfrom the API. Since exceptions are getting consumed, throwing them in an errback causes the exception to silently disappear. Useend. - Added
endas both an API method and a promise-chain ending method. It causes propagated rejections to be thrown, which allows Node to write stack traces and emituncaughtExceptionevents, and browsers to likewise emitonerrorand log to the console. - Added
joinandwaitas promise chain functions, so you can wait for variadic promises, returning your own promise back, or join variadic promises, resolving with a callback that receives variadic fulfillment values.
Changelog
0.4.4
endno longer returns a promise. It is the end of the promise chain.- Stopped reporting thrown exceptions in
whencallbacks and errbacks. These must be explicitly reported through.end(),.then(null, Q.error), or some other mechanism. - Added
reportas an API method, which can be used as an errback to report and propagate an error. - Added
reportas a promise-chain method, so an error can be reported if it passes such a gate.
Changelog
0.4.1
- Added an "end" method to the promise prototype, as a shorthand for waiting for the promise to be resolved gracefully, and failing to do so, to dump an error message.
Changelog
0.4.0 - BACKWARD INCOMPATIBLE*
- *Removed the utility modules. NPM and Node no longer expose any module except the main module. These have been moved and merged into the "qq" package.
- *In a non-CommonJS browser, q.js can be used as a script. It now creates a Q global variable.
- Fixed thenable assimilation.
- Fixed some issues with asap, when it resolves to undefined, or throws an exception.
