node-barrierpoints

This library provides minimal control flow based on barrier points, as known from other languages like Java for example (java.util.concurrent.CountDownLatch / java.util.concurrent.CyclicBarrier).

Usage

Create a barrier object, with a required count of parties to wait for and optional callback for success or abortion:

var barrier = new Barrier(count, successCallback, abortCallback);

Within each party code, you must either call barrier.submit() or barrier.abort() in order to signal the outcome.

For more examples, please have a look at the examples/ directory.
