I have my proof of concept for using React within Koha completed! You can see it here: https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=17297 Please give it a try! So, I've written this development ( at least in part ) in both Angular and React. I know Angular 2 is out but here are my thoughts so far. 1) It's much easier to think in React than in Angular. React is for the most part just Javascript. It's far less opinionated than Angular. They saying goes React is Javascript and Angular is Angular. I think the flexibility of React works well within the Koha ecosystem. 2) Writing React feels much more like programming. I think it's much faster to develop reactive and ajax features in React than it is using jQuery. 3) React makes it pretty easy to create widgets that we can drop in to a given page and have just work. Pretty much anything that shows up on multiple pages would make for a good React widget. Think the holds table which is on the checkouts page and the patron details page. It is ajaxified now, but a far far cleaner version could be written in React. 4) React is just a view layer. Angular is a full MVC framework with many pieces we don't really need. I think React is probably the way to go for Koha. I like Angular but for Koha in particular, I think React is a better fit. I think we really need to get this decision made as soon as possible. If anyone has opinions, please let everyone know!
