Examples

nui-sftp

nui-sftp is a terminal emulator, file explorer and ssh & sftp client built using nui. It is my nui dogfooding project. It is a good example of a non-trivial application built with nui, and is available here: https://github.com/5cript/nui-sftp

Using SAPUI5 Components

(WARNING: I experience serious performance problems caused by these components when 100+ components are used, because each and every single component calls getComputedStyle on creation causing forced reflows.)

To use them, see this repo: https://github.com/NuiCpp/ui5

Using Bootstrap and some custom CSS
