Canonical data-table example for the ContractSpec stack.

What This Demonstrates

• The same account-grid example across @lssm-tech/lib.contracts-spec, @lssm-tech/lib.ui-kit, @lssm-tech/lib.ui-kit-web, and @lssm-tech/lib.design-system.
• Client-mode and server-mode table controllers with sorting, pagination, single and multiple selection, column visibility, resizing, left/right pinning, and row expansion.
• Loading states, empty states, design-system header actions, toolbar/footer slots, and a visible row-interaction log.
• A declarative DataViewSpec table contract that adapts onto the same headless table stack.
• Sandbox-friendly UI packaging for a focused canonical example instead of a full business template.

Running Locally

From examples/data-grid-showcase:

• bun run dev
• bun run build
• bun run test
• bun run typecheck

Usage

Usar @lssm-tech/example.data-grid-showcase as the canonical reference for ContractSpec table capabilities, or import its exported contracts and UI into docs, sandboxes, and internal examples.

Live surfaces

• Sandbox: /sandbox?template=data-grid-showcase
• Docs example: /docs/examples/data-grid-showcase
• Generated reference: /docs/reference/data-grid-showcase/data-grid-showcase

Arquitectura

• src/contracts/ owns the sample query contract and declarative data view spec.
• src/docs/ contains docblocks and documentation-facing exports.
• src/example.ts is the example manifest surfaced by @lssm-tech/module.examples.
• src/ui/ contains the table showcase component, the primitive/composed table lanes, and demo data/helpers.

Data table contract example

The declarative contract lane uses the same account-grid example exposed in the interactive showcase:

import { defineDataView } from '@lssm-tech/lib.contracts-spec/data-views';
import { ListDataGridShowcaseRowsQuery } from './data-grid-showcase.operation';

export const DataGridShowcaseDataView = defineDataView({
  meta: {
    key: 'examples.data-grid-showcase.table',
    version: '1.0.0',
    entity: 'account',
    title: 'Data Grid Showcase Table',
    description:
      'Declarative DataViewSpec for the ContractSpec table showcase.',
    domain: 'examples',
    owners: ['@platform.core'],
    tags: ['examples', 'table', 'data-grid'],
    stability: 'experimental',
  },
  source: {
    primary: {
      key: ListDataGridShowcaseRowsQuery.meta.key,
      version: ListDataGridShowcaseRowsQuery.meta.version,
    },
  },
  view: {
    kind: 'table',
    executionMode: 'client',
    selection: 'multiple',
    columnVisibility: true,
    columnResizing: true,
    columnPinning: true,
    rowExpansion: {
      fields: ['notes', 'renewalDate', 'lastActivityAt'],
    },
    initialState: {
      pageSize: 4,
      hiddenColumns: ['notes'],
      pinnedColumns: {
        left: ['account'],
      },
      sorting: [{ field: 'arr', desc: true }],
    },
    fields: [
      { key: 'account', label: 'Account', dataPath: 'account', sortable: true },
      { key: 'owner', label: 'Owner', dataPath: 'owner', sortable: true },
      { key: 'status', label: 'Status', dataPath: 'status', sortable: true },
      { key: 'notes', label: 'Notes', dataPath: 'notes' },
    ],
  },
});

Notes

• This package is intentionally narrow: it exists to showcase the full table stack, not to simulate a full vertical business template.
• The same table stack is reused by the larger examples in analytics-dashboard, crm-pipeline, integration-hub, and agent-console, but this package is the canonical source of truth.
