If only opa were released under a license that let normal people feel safe about experimenting with it/reading its source :(.
Most of Opa is now licensed under the MIT license and all of it is open source.
We changed the license two years ago.
I'd never heard of Opa before. Thanks for sharing, it looks interesting!
Opa should be more popular.
Also, fruitmachine (Github)- Financial Times - Graphics Lab. They say it handles multiple pages better then React. They also claim to have had the React concept first.
I never hear of it, i will give it a look. Thanks
Fwiw the Lift web framework has been diffing a server-side virtual DOM back to the client-side DOM via Ajax since 2007. And I wouldn't be surprised if the concept existed elsewhere even before that. Claims to be the first to have had the idea should be taken with a grain of salt.
