Paul Trowbridge a6e6efd36e Switch /data endpoint to Arrow IPC stream with pg cursor batching 
Server streams rows from a pg cursor in 10k-row batches, building Arrow
record batches incrementally and piping them as chunked HTTP response —
Node.js heap stays bounded regardless of dataset size.

Client fetches as arrayBuffer() and loads directly into Perspective worker
(native Arrow path, no JSON deserialization). X-Row-Count header drives
a non-blocking banner for datasets >= 500k rows. validCols now derived
from col_meta rather than from row keys.

React + Vite

This template provides a minimal setup to get React working in Vite with HMR and some ESLint rules.

Currently, two official plugins are available:

React Compiler

The React Compiler is not enabled on this template because of its impact on dev & build performances. To add it, see this documentation.

Expanding the ESLint configuration

If you are developing a production application, we recommend using TypeScript with type-aware lint rules enabled. Check out the TS template for information on how to integrate TypeScript and typescript-eslint in your project.
