Anyone have a sane and performant way that they break out of a domain or action such as middleware? I am trying to design such behavior but am faced with a multitude of interesting issues. The classic example of this problem can be seen with Array.prototype.forEach (though this has the easier synchronous execution for breaking):
```javascript // we only want to print first 2 items [1, 2, 3].forEach(function (item) { if (item > 2) { return; } console.log(item); }); ``` We often see the error first callback cause a fast fail on waterfall style control flow, but what if we are not issuing an error, but rather a terminating condition (making all middleware after it ignored)? Right now my only solution is to add another callback to arguments ala: ```javascript function finish(creds, finish, next) { if (creds == 'secret') finish(null, 'user/mary'); else next(null, creds); } actor.perform('auth', creds, finish, next); ``` This seems, a bit... overkill to type out though. Anyways, looking for suggestions. -- Job Board: http://jobs.nodejs.org/ Posting guidelines: https://github.com/joyent/node/wiki/Mailing-List-Posting-Guidelines You received this message because you are subscribed to the Google Groups "nodejs" group.
