@dzgrid/core

The model of DzGrid, a data grid written from scratch: typed row identities, calendar days kept apart from instants, sorting, filtering, quick search, selection, paging, server rows. No DOM, no framework, no Date, no dependency: the same results in Node and in the browser.

Most applications install it beside @dzgrid/dom, which draws the grid; the core alone serves a server, a test or another renderer.

Install

npm install @dzgrid/core

A first use

import { parseDay, zoneDayBounds } from '@dzgrid/core';

const day = parseDay('2026-03-05');               // a calendar day, never a Date
if (day) {
  const { from, to } = zoneDayBounds(day, 'Africa/Algiers'); // that day in that zone, half-open, in ms
  console.log(from, to);
}

Rows from a server, with a request gate that shows only the answer to the last request:

import { sourceRows } from '@dzgrid/core/server';

const source = sourceRows({ fetch: (req) => api.patients(req) }); // req: filters, sort, page, abort signal
