useDataTable

Hook for schema-driven data tables with pagination, sorting, filtering, and selection.

React Native uses the same useDataTable hook from @ybyra/react.

Basic Usage

import { useDataTable } from '@ybyra/react'
import { Scope } from '@ybyra/core'

function PersonList() {
  const table = useDataTable({
    schema: PersonSchema.provide(),
    scope: Scope.index,
    handlers: personHandlers,
    hooks: personHooks,
    component: componentContract,
    translate: t,
  })

  if (table.loading) return <ActivityIndicator />
  if (table.empty) return <Text>No records found</Text>

  return (
    <View>
      <FlatList
        data={table.rows}
        keyExtractor={(row) => table.getIdentity(row)}
        renderItem={({ item: row }) => (
          <View>
            {table.columns.map((col) => (
              <Text key={col.name}>
                {table.formatValue(col.name, row[col.name], row)}
              </Text>
            ))}
          </View>
        )}
      />

      <View>
        <Button
          title="Previous"
          disabled={table.page <= 1}
          onPress={() => table.setPage(table.page - 1)}
        />
        <Text>Page {table.page} of {table.totalPages}</Text>
        <Button
          title="Next"
          disabled={table.page >= table.totalPages}
          onPress={() => table.setPage(table.page + 1)}
        />
      </View>
    </View>
  )
}

totalPages	number	Total page count
setPage(page)	function	Navigate to page
setLimit(limit)	function	Change page size

Utilities

Method	Description
reload()	Re-fetch current page data
formatValue(name, value, record)	Format a cell value using column config
getIdentity(record)	Get the identity key for a record

Column Configuration

Fields become table columns when marked with .column():

text().column()               // basic column
text().column().sortable()    // sortable
text().column().filterable()  // filterable

Fetch Hooks

Table data is loaded through fetch hooks:

const personHooks = PersonSchema.hooks({
  fetch: {
    [Scope.index]: async ({ params }) => {
      return personService.paginate(params)
    },
  },
})

The params object contains pagination, sorting, and filter state:

interface PaginateParams {
  page: number
  limit: number
  sort?: string
  order?: 'asc' | 'desc'
  filters?: Record<string, unknown>
}

The hook expects a PaginatedResult:

interface PaginatedResult<T> {
  data: T[]
  total: number
  page: number
  limit: number
}

ResolvedColumn

interface ResolvedColumn {
  name: string
  config: FieldConfig
  table: TableConfig
}
