ReactJS Tip: Show exceptions from Flux Dispatcher callbacks

Being an architectural pattern, it’s largely a do-it-yourself kind of deal. That is, except for an implementation of the Dispatcher, which is provided in the flux package on npm. The Dispatcher accepts callbacks with its register method, and invokes those callbacks anytime an action is dispatched to it. One curious behavior of the Dispatcher, though, is that it will eat any exception that occurs in a callback, and keep chugging along. Presumably, this is so that one failing callback doesn’t cause the whole application to blow up. Var vomitify = function(f) { return function() { try { f.apply(this, arguments); } catch(e) { console.error(e.stack); } }}; Note: Here, we reference the console object, which will fail spectacularly in older versions of IE when you don’t have the developer console open. Now, we’ll override the dispatch method of AppDispatcher to use vomitify.
