when - npm Package Versions
Changelog
2.3.0
- New
promise.tapfor adding side effects to a promise chain. - New
MessageChannelscheduler reduces "time-to-first" handler, in environments that support it. - Performance optimizations for promise resolution.
- Internal architecture improvements to pave the way for when.js 3.0.0.
Changelog
2.2.1
- Fix for
when.defer().reject()bypassing the unhandled rejection monitor. (#166) - Fix for
when/function,when/callbacks, andwhen/node/functionnot preservingthisArg. (#162) - Doc clarifications for
promise.yield. (#164)
Changelog
2.2.0
- New experimental promise monitoring and debugging via
when/monitor/console. - New
when.promise(resolver)promise creation API. A lighter alternative to the heavierwhen.defer() - New
bindCallbackandliftCallbackinwhen/node/functionfor more integration options with node-style callbacks.
Changelog
2.1.0
- New
when.settlethat settles an array of promises, regardless of whether the fulfill or reject. - New
when/guardgeneralized concurrency guarding and limiting - New
promise.inspectfor synchronously getting a snapshot of a promise's state at a particular instant. - Significant performance improvements when resolving promises with non-primitives (Arrays, Objects, etc.)
- Experimental vert.x support
- DEPRECATED:
onFulfilled,onRejected,onProgresshandler arguments towhen.all,when.any,when.some. Use the returned promise'sthen()(orotherwise(),ensure(), etc) to register handlers instead.- For example, do this:
when.all(array).then(onFulfilled, onRejected)instead of this:when.all(array, onFulfilled, onRejected). The functionality is equivalent.
- For example, do this:
Changelog
2.0.0
- Fully asynchronous resolutions.
- Promises/A+ compliance.
- New
when/keysmodule withall()andmap()for object keys/values. - New
promise.ensureas a better, and safer, replacement forpromise.always. See discussion as to whypromise.alwaysis mistake-prone.- DEPRECATED:
promise.always
- DEPRECATED:
lift()is now the preferred name for what wasbind()in when/function, when/node/function, and when/callbacks.- DEPRECATED:

1.8.1
- Last 1.x.x release before 2.0.0 barring critical fixes.

- Documentation updates and fixes. Thanks, @unscriptable!
- DEPRECATED:
deferred.progressanddeferred.resolver.progress. Usedeferred.notifyanddeferred.resolver.notifyinstead. - DEPRECATED:

when/timedmodule. Usewhen/delayandwhen/timeoutmodules instead.
Changelog
1.8.0
- New when/function, when/node/function, and when/callbacks with functional programming goodness, and adapters for turning callback-based APIs into promise-based APIs. Kudos @riccieri!

- New when/poll promise-based periodic polling and task execution. Kudos @scothis!
