Pros
Pro Real time communication between server and client
Derby enables the client and server to sync models across the board in real-time.
Pro Views are rendered on the server
Derby renders it's client-side views on the server. This means that there's no "delay" in serving the content to the browser when the user requests it. It's also very helpful for SEO purposes.
Pro Same code can be run on the client and server
The same code can be run on both the server and the client, because Derby is a full-stack JavaScript-everywhere platform.
Pro Views are rendered on the server progressively
Catberry employs server-side progressive rendering to render its views in the browser. This is achieved through Node's streams and parallel rendering.
Pro Easy to understand how a Catberry application works even when it starts getting complicated
Flux is a platform agnostic pattern which can technically be used with any application or programming language.
One of Flux' main features is that it enforces uni-directional data flow which means that views do not change the data directly.
This is useful because this way it's easier to understand an application as it starts getting more complicated. By having two-way data binding, it can lead to unpredictable changes, where changing one model's data would end up updating another model. By using the Flux architecture, this can be avoided.
Pro SEO friendly
The search crawler receives the rendered page from the server just like a normal user would. This makes applications developed with Catberry very SEO-friendly.
Cons
Con Small community
Derby seems to have a small community of followers, at least compared to other Node full-stack frameworks. So it could be difficult for a beginner to find examples or help if they get stuck somewhere in their development.
Con Seems to be very popular only in non-English speaking countries
Catberry seems to be very popular in countries where English is not a native language (for example Russia). For this reason it can be very hard to find any resources in English outside the Catberry website.
