Keep folders organized​

Various functions may produce Iconize objects, for storing large chunks of data, which are copied to ./.iconized/ folder in the notebook directory. Any dropped images or files will be uploaded to ./attachments/ directory. Therefore it is important to have a clear separation between your projects.

Use NotebookStore for portability​

If you want your notebook to be exported to a single editable .html Static HTML, use NotebookStore as a persistent storage for your raw data. In such case all images, graphs, and stored data will be kept.

Install everything locally​

We promote the idea of storing libraries or paclets for Wolfram Language locally for each project. There is no other way to provide the reliable way of computing, storing data, reproducibility and independence from any remote resources

example of a built-in package manager
PacletRepositories[{
    Github -> "https://github.com/KirillBelovTest/GPTLink"
}]

<<KirillBelov`GPTLink`

this will create a folder with all used paclets and keep them up to date if needed

Do not use Dynamic​

We rely on a completely different architecture to handle interactivity and graphics updates compared to Wolfram Mathematica.

In general Manipulate is implemented as well, but it is not recommend to use often due to its impact to the system performance.

Dynamic​

Buttons, sliders are event-driven, i.e. you need to subscribe to them using EventHandler. All dynamic updates are handled using Offload approach. For example

length = 1.0;
EventHandler[InputRange[-1,1,0.1], Function[l, length = l]]

Graphics[Rectangle[{-1,-1}, {length // Offload, 1}]]

Manipulate​

In general there is built-in function for simple 2D plots - ManipulatePlot, however, for something more complicated - you need to craft it by yourself using building Offset and simple graphics primitives such as Line, Polygon and etc as building blocks.
