  if (response.error) {
    // Handle query error
  } else {
    // Handle successful query
  }
};

Pagination with Supabase in React Native

import { supabase } from '@supabase/supabase-js';

const { db } = supabase;

const handlePaginate = async (table, query, pageSize, pageNumber) => {
  const response = await db.paginate(table, query, pageSize, pageNumber);
  if (response.error) {
    // Handle pagination error
  } else {
    // Handle successful pagination
  }
};

Sorting & Filtering with Supabase in React Native

To sort and filter data from Supabase in React Native, we can use the sort and where methods from the supabase library:

import { supabase } from '@supabase/supabase-js';

const { db } = supabase;

const handleSortAndFilter = async (table, query) => {
  const response = await db
    .sort(table, query, { field: 'name', direction: 'asc' })
    .where(table, query, { age: { gte: 18 } });
  if (response.error) {
    // Handle sort and filter error
  } else {
    // Handle successful sort and filter
  }
};

Supabase Storage Integration in React Native

Supabase provides an API for working with storage in React Native apps. To upload a file to Supabase in React Native, we can use the upload method from the supabase library:

import { supabase } from '@supabase/supabase-js';

const { storage } = supabase;

const handleUpload = async (file) => {
  const response = await storage.upload(file);
  if (response.error) {
    // Handle upload error
  } else {
    // Handle successful upload
  }
};
