Addons not being loaded to global state

[davidlormor]

This appears to be a similar issue to #315. Configuration and everything was set up correctly just like the previous issue, but when trying to use ReactCSSTransitionGroup in a component (defined in app/assets/javascripts/admin/components) I get a the following error in the browser console:

Uncaught ReferenceError: ReactCSSTransitionGroup is not defined

I can find the "development_with_addons" react file being loaded, but apparently the addon components being defined in this file are not being loaded to the global state for other components to use.

Adding var ReactCSSTransitionGroup = React.addons.CSSTransitionGroup; to application.js resolves the issue. Just wonder if there's a cleaner/more automated way to ensure that all components are being required on load?

Yep, it's intentional that they're exposed on React.addons right now. That's the way the "official" react bundle does it (eg, https://fb.me/react-with-addons-0.14.6.min.js), and besides that, that's how it was when I started working on it, so I don't want to break it for people :P

I'd also love to see a more flexible & powerful way to load those things. You can see the existing build setup here: https://github.com/reactjs/react-rails/tree/master/react-builds. The addons object is created in addons-object, then tacked on to React.

I think it'd be nice to pick-and-choose your addons with //= require. Some people also requested making it more require-js friendly (although that doesn't apply to me personally).

You can get them from React.addons either by adding addons = true in config, or requiring them one-at-a-time (see the bottom of https://github.com/reactjs/react-rails#reactjs-builds)

Hope that helps!

Thanks @davidlormor for the question and @rmosolgo for the clarification!

Just to be clear for anyone else running across this problem.

You'll need config.react.addons = true in application.rb and

`<React.addons.CSSTransitionGroup ... >
</React.addons.CSSTransitionGroup/>`

I couldn't get a-la-carte to work either. c18aa38
