Tubular Common is a (now deprecated) TypeScript/JavaScript library that defines shared models (e.g., GridRequest, ColumnModel) and a data‑transformer used to turn a plain array of objects into the request/response format required by Tubular data‑grid components. It’s aimed at developers building front‑end grids (Angular, React, etc.) or back‑end services who need a lightweight way to apply sorting, filtering, paging and aggregation on in‑memory data before sending it to a Tubular UI component.
