A Lopebook is a hermetic, self-hosted, self-sustainable, recursively exportable, offline-first, file-first, web-based reactive open-source programming substrate built on Observable runtime. It is an ideal platform for building programmable, reactive applications that work offline, that require no runtime to be installed.
The “Tour of Lopecode” is an interactive introduction to some of the things you can build in Lopebooks
The “vision statement” explains the endgoal in more detail and is itself a lopebook you can hack around with.
The “audio sequencer” is an example of a non-trivial application that remembers its state.
The blog post reactive reflective testing explains how reactive programming can super charge unit testing and development. It also shows the value of using lopebooks are interactive blog posts.
Jumpgate can transform Observable notebooks to lopecode.
