Hi, > 1. Support communication with server-side thru AMF3
This is currently being worked on, performance however may be different. > 2. Support communication with server-side thru REST This is possible now and work quite well in my experience. > 3. Easy to build components like MXML Composing applications / views etc etc from components is easy enough, however currently not all FlexJS component can be extended via MXML. > 4. Easy to install on IDEA IDE like Flex SDK Currently it requires some manual steps (documented on wiki) you don't need to set any environment variables or run any scripts if you use the installer. > 5. Binding and two-way binding easier as Flex. Basic binding works, I’ve not tried two way binding but I'd expect it’s not supported yet. I’m surprised you list two-way binding as a needed feature and I can only think of a few cases I used it FlexSDK application and it can easily be replaced with a little code. Thanks, Justin
