pasync

pasync

Version of async that uses promises instead of callbacks.

var pasync = require('pasync');

function getUserById(id) {
	return new Promise(...);
}

var userIds = [1, 2, 3, 4, 5, 6];

pasync.mapLimit(userIds, 2, getUserById).then(function(users) {
	// ...
});

You can also return values instead of promises from the iterator functions, and these will be converted into resolved promises. Exceptions thrown from iterator functions will be converted into rejected promises.

Additionally, this implements error handling for async functions that don't natively have error handling, such as async.filter .
