expo-flash-datagrid

React Native data grid and Expo data table built on top of FlashList, with virtualization, sorting, filtering, global search, pagination, row selection, row actions, and localization.

expo-flash-datagrid is designed for apps that need a more capable table than FlatList, while still keeping React Native ergonomics and strong TypeScript support.

If you are looking for a React Native data table, Expo data grid, mobile datagrid, or a FlashList-based grid component, this package is built for that use case.

What It Is

This package focuses on mobile-first tabular data experiences for Expo and React Native apps:

• CRM and admin lists
• inventory and catalog screens
• financial and operational tables
• searchable and filterable mobile datasets
• server-driven tables with pagination or infinite loading

Current Status

Expo-only for now.

The package currently depends on @expo/vector-icons and expo-font, so it is intended for Expo projects at the moment. A bare React Native version would require replacing that dependency chain first.

Features

• FlashList-powered rendering for large datasets
• Client and server data modes
• Sorting, filtering, global search, pagination, and infinite loading
• Column visibility management
• Selection model with mobile-oriented long-press behavior
• Row action menus and actions columns
• Theme overrides and locale overrides
• Built-in English and Portuguese locale bundles
• Exported pure utilities for sorting, filtering, search, and pagination

Why This Package

• Better fit than a plain FlatList when you need real table behavior on mobile
• Strong TypeScript API for rows, columns, filters, pagination, and events
• Familiar data-grid concepts inspired by desktop grids, adapted to touch-first UX
• Good fit for Expo apps that need an MUI-like data grid experience in React Native

Installation

This package currently expects an Expo-compatible setup because it uses @expo/vector-icons internally and safe-area aware modal surfaces.

If you already have an Expo app, react, react-native, expo, and expo-font are usually already present.

npm

npm install expo-flash-datagrid @shopify/flash-list react-native-safe-area-context @expo/vector-icons expo expo-font

yarn

yarn add expo-flash-datagrid @shopify/flash-list react-native-safe-area-context @expo/vector-icons expo expo-font

Required peers in the host app:

• react
• react-native
• expo
• expo-font
• @expo/vector-icons
• @shopify/flash-list
• react-native-safe-area-context

Wrap your app with SafeAreaProvider:

import { SafeAreaProvider } from 'react-native-safe-area-context';

export default function App() {
  return (
    <SafeAreaProvider>
      <YourScreen />
    </SafeAreaProvider>
  );
}

Quick Start

import { useState } from 'react';
import { View } from 'react-native';
import {
  DataGrid,
  type ColumnDef,
  type QueryState,
} from 'expo-flash-datagrid';

type User = {
  id: string;
  name: string;
  email: string;
  age: number;
  active: boolean;
};

const rows: User[] = [
  {
    id: '1',
    name: 'Alice',
    email: '[email protected]',
    age: 29,
    active: true,
  },
  {
    id: '2',
    name: 'Bruno',
    email: '[email protected]',
    age: 34,
    active: false,
  },
];

const columns: ColumnDef<User>[] = [
  { field: 'name', headerName: 'Name', flex: 1, searchable: true },
  { field: 'email', headerName: 'Email', flex: 1.2, searchable: true },
  { field: 'age', headerName: 'Age', type: 'number', width: 90 },
  { field: 'active', headerName: 'Active', type: 'boolean', width: 90 },
];

const initialState: QueryState = {
  paginationModel: { page: 0, pageSize: 25 },
  sortModel: [],
  filterModel: { items: [], logicOperator: 'and' },
  searchText: '',
  columnVisibilityModel: {},
  selectionModel: [],
};

export function UsersScreen() {
  const [state, setState] = useState<QueryState>(initialState);

  return (
    <View style={{ flex: 1 }}>
      <DataGrid<User>
        mode="client"
        rows={rows}
        columns={columns}
        state={state}
        onStateChange={setState}
        checkboxSelection
        zebraRows
        pageSizeOptions={[10, 25, 50]}
        style={{ flex: 1 }}
      />
    </View>
  );
}

Data Modes

Client mode

In client mode, the grid applies these steps locally on rows:

1. Filter
2. Search
3. Sort
4. Paginate

Use this mode when the full dataset is already available in memory.

<DataGrid<User>
  mode="client"
  rows={rows}
  columns={columns}
  state={state}
  onStateChange={setState}
  enableMultiSort
  searchDebounceMs={300}
  pageSizeOptions={[10, 25, 50]}
/>

Server mode

In server mode, the grid does not transform rows locally. It emits state changes and you fetch the correct slice from your API.

import { useEffect, useState } from 'react';
import {
  DataGrid,
  type QueryState,
} from 'expo-flash-datagrid';

const initialState: QueryState = {
  paginationModel: { page: 0, pageSize: 25 },
  sortModel: [],
  filterModel: { items: [], logicOperator: 'and' },
  searchText: '',
  columnVisibilityModel: {},
  selectionModel: [],
};

export function ServerUsersScreen() {
  const [state, setState] = useState<QueryState>(initialState);
  const [rows, setRows] = useState<User[]>([]);
  const [rowCount, setRowCount] = useState(0);
  const [loading, setLoading] = useState(false);

  useEffect(() => {
    setLoading(true);

    // Call your API using:
    // state.paginationModel
    // state.sortModel
    // state.filterModel
    // state.searchText
    //
    // Then update rows and rowCount.

    setLoading(false);
  }, [state]);

  return (
    <DataGrid<User>
      mode="server"
      rows={rows}
      columns={columns}
      rowCount={rowCount}
      state={state}
      onStateChange={setState}
      loading={loading}
    />
  );
}

Common Customizations

Empty state and localization

The grid ships with en and pt locale bundles. You can override the empty-state text directly with emptyLabel or provide a partial localeText.

<DataGrid<User>
  mode="client"
  rows={rows}
  columns={columns}
  locale="pt"
  emptyLabel="Nenhum cliente encontrado"
  localeText={{
    rowsPerPage: 'Itens por pagina',
  }}
/>

Exported helpers:

• EN_LOCALE_TEXT
• PT_LOCALE_TEXT
• resolveLocaleText
• formatLocale

Theme overrides

<DataGrid<User>
  mode="client"
  rows={rows}
  columns={columns}
  theme={{
    headerBackground: '#E0F2FE',
    toolbarBackground: '#F0F9FF',
    footerBackground: '#F0F9FF',
    selectionBackground: '#DBEAFE',
    rowAltBackground: '#F8FAFC',
    borderRadius: 16,
  }}
/>

Row actions

rowActions opens a native-feeling action menu, by default on long press.

import { MaterialIcons } from '@expo/vector-icons';

const rowActions = [
  {
    key: 'edit',
    label: 'Edit',
    icon: ({ color, size }: { color: string; size: number }) => (
      <MaterialIcons name="edit" color={color} size={size} />
    ),
    onPress: ({ rowId }: { rowId: string }) => {
      console.log('edit', rowId);
    },
  },
];

<DataGrid<User>
  mode="client"
  rows={rows}
  columns={columns}
  rowActions={rowActions}
/>

Actions column

You can also add a dedicated column with type: 'actions' and provide per-row actions.

import { MaterialIcons } from '@expo/vector-icons';

const columns: ColumnDef<User>[] = [
  { field: 'name', headerName: 'Name', flex: 1 },
  {
    field: 'actions',
    headerName: 'Actions',
    type: 'actions',
    width: 132,
    actions: ({ rowId }) => [
      {
        key: `edit-${rowId}`,
        label: 'Edit',
        icon: ({ color, size }) => (
          <MaterialIcons name="edit" color={color} size={size} />
        ),
        onPress: () => {
          console.log(rowId);
        },
      },
    ],
    actionTrigger: {
      display: 'both',
      label: 'Actions',
      icon: ({ color, size }) => (
        <MaterialIcons name="more-horiz" color={color} size={size} />
      ),
    },
  },
];
