Architecture

Univer is written in typescript and designed according to the plug-in architecture. The functions outside the core are developed in the form of plug-ins. In the future, a plug-in market will be built to meet more personalized needs

Rendering engine

Univer sheet, document, and slide adopt the same rendering engine architecture, which abstracts the application into text flow, table, canvas, and core part triggers rendering, and object is the renderer.
