asynchronously

asynchronously

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.

Methods

• attempt(fn, ...args) - Call a function with the given arguments and reject caught errors
• auto(tasks) - Run tasks by specifying dependent additional dependent tasks, resolves to an object containing the mapping of task property names to task result values
• delayed(fn, ms) - Execute a function after a given number of milliseconds and resolve
• each(items, [limit,] iterator(item, index, array)) - Execute an iterator for a given set of items with a limit on the number of simultaneous operations
• every(items, [limit,] iterator(item, index, array)) - Resolve only if the iterator resolves for each item
• map(items, [limit,] iterator(item, index, array)) - Collect the results of all items passed to the iterator
• reduce(items, iterator(previous, item, index, array), accumulator = []) - Sequentially call an iterator for each item and include the previous result starting with the value of the accumulator
• some(items, [limit,] iterator(item, index, array)) - Resolve the first item that resolves for the iterator, rejects if all reject
• wrap(fn, ...args) - Call a function using node callback style and resolve or reject to a promise
