This really depends on the type of application you are building and the size and experience of the team.
If you are working on a small project with a very small team, then a singleton/static implementation will work just fine. The problem comes when you work on larger apps that perhaps contain modules and have a larger team of developers. In that case you need to have some rules amongst the team to decide when and how the eventbus can be used. If not, you'll quickly end up with an eventbus that is abused and handles way too much communication. This makes it hard to debug, maintain and test the code. In this scenario I would advise a strategy in which the eventbus is injected and managed in a central location (an IoC container). - Christophe 2013/3/7 Frédéric THOMAS <webdoubl...@hotmail.com> > Hi John, > > I said "inspired" by those frameworks, which, for puremvc multicore at > least doesn't use the singleton pattern but the multiton's one, I guess is > better than completly reinvent the wheel and it might be light enought > extracting what it needs only but maybe some else has a better solution. > > -Fred > > -----Message d'origine----- From: John Cunliffe > Sent: Thursday, March 07, 2013 3:11 PM > To: dev@flex.apache.org > Subject: Re: An Eventbus for Apache Flex applications > > > I think Sebastian knows these frameworks like most flex developers.
