About Blocks in O2S

Blocks are self-contained, reusable UI components that combine harmonizing and frontend components into a single package. Each block is independently packaged as an NPM module and includes three primary parts: API Harmonization Module, Frontend Components, and SDK Methods. Blocks allow you to quickly add or remove functionality without impacting other components of the application.
