asynchronously iterate over items and resolve promises instead of callbacks
This is the async library for promises, without a lot of extra dependencies like in bluebird.
attempt(fn:Function|AsyncFunction, ...args:Array<Any>):Promise<Any>
- Call a function with the given arguments and reject caught errorsauto(tasks:Object<String, AsyncFunction|Array<String|AsyncFunction>>):Promise<Object>
- Run tasks by specifying dependent additional dependent tasks, resolves to an object containing the mapping of task property names to task result values. See async.auto for how to constructtasks
delayed(fn:Function|AsyncFunction, ms:Number = 10):Promise<Any>
- Execute a function after a given number of milliseconds and resolve the promise to the function return valueeach(items:Iterable, [limit:Number = POSITIVE_INFINITY,] iterator:Function(item:Any, index:Number, items:Iterable)):Promise
- Execute an iterator for a given set of items with a limit on the number of simultaneous operationsevery(items:Iterable, [limit:Number = POSITIVE_INFINITY,] iterator:Function(item:Any, index:Number, items:Iterable)):Promise<Boolean>
- Resolves true if all iterated items resolve true, otherwise resolves falsemap(items:Iterable, [limit:Number = POSITIVE_INFINITY,] iterator:Function(item:Any, index:Number, items:Iterable))
- Collect the results of all items passed to the iteratorreduce(items:Iterable, iterator(previous:Any, item:Any, index:Number, items:Iterable), accumulator:Any)
- Sequentially call an iterator for each item and include the previous result starting with the value of the accumulatorsome(items:Iterable, [limit:Number = POSITIVE_INFINITY,] iterator:Function(item:Any, index:Number, items:Iterable)):Promise<Boolean>
- Resolves true if any iterated items resolve true, otherwise resolves falsewrap(fn:Function, ...args:Array<Any>):Promise<Any>
- Call a function using node callback style and resolve or reject to a promiseonce(event:String|Array<String>, target:EventEmitter, timeout:Number = -1):Promise<Any>
- Wait for one or more events on an EventEmitter and optionally timeout the waitwait(ms:Number = 10)
- Use a promise for a setTimeout call
- v2.0.0
- Use async / await where possible
- Change behavior in every/some where errors would be swallowed
- Add
