Design Overview

Projection Grid Core

The original projection-grid was implemented only for BackboneJS. As an aged
frontend framework, it's no longer as competitive. Comparing to new libraries
like ReactJS/VueJS, BackboneJS's limitation on performance and robustness are
significant.

However, the requirement of a highly extensible data grid applies to all UI
frameworks, and the design pattern projection-grid used is framework neutral. To
make the design benefit more people in modern world, we'd like to abstract the
framework indepedent part (from projection-grid) and create a core component, on
top of which, we can build the ReactJS/VueJS version as well as the Backbone
version to continue support the legacy projects.
