`carefree-drawboard` made assumptions that:
* It is a painful process to spend time thinking and designing the layout of various UIs.
* Most user interactions can be abstracted into "send something to server" & "receive something to server".
* A completely decoupled system is what we dreamed of, because it can be easily customized, extended and maintained.
* An infinite drawboard is capable of building (almost) all the desired applications.
So, we derived the following design principles:
* Everything is a plugin on an infinite drawboard.
* Plugin Styles should be fully declarative and should contain a smart layout system (which should also be declarative).
* Plugin Logics should only have access to the data from:
> Itself (e.g., some input fields declared by the Styles).
> The selecting Node(s).
Under these principles, no matter what programming languages (even JSON, if your plugins contain no logics) you are using, you can easily extend the functionality of `carefree-drawboard` by writing plugins.
And since:
* We love Python.
So (currently) we provide a python binding, the `cfdraw` package, for you to write plugins (both styles and logics) using Python. However, theoretically speaking, any backend programming languages are able to write plugins that work with `carefree-drawboard`.
