supabase react

[Justol]

Supabase Integration:
Please help me with integrating supabase. I am trying to fetch locations directly from your Supabase backend using the official Supabase JavaScript client.
Environment Variables:
I have correctly placed my .env file in my project root (MailandShip-1108) and set the VITE_SUPABASE_URL and VITE_SUPABASE_ANON_KEY variables using the values provided by Supabase support., and still not connecting to and fetching data directly from supabase. I want first to accomplish this in my dev environment where I added a location tab in the main menu as you can see.

What does the code look like that should load this data? Do you have row level security (RLS) enabled? if yes what does your RLS policies look like?

Hello, thanks for reaching out: I asked copilot, an here are the exact code snippets that fetch data from Supabase and the React component that fetches and displays location data, along with their full file paths:

---

1. Supabase Data Fetching (Service Layer)

File: locationService.ts

import { supabase } from '@/lib/supabase';
import type { Location, LocationStats } from '@/types';

export const locationService = {
  async getLocationsByAdminId(userId: string): Promise<Location[]> {
    // First try direct admin relationship
    const { data: directLocations, error: directError } = await supabase
      .from('locations')
      .select('*')
      .eq('admin_id', userId);

    if (!directError && directLocations?.length > 0) {
      return directLocations;
    }

    // If no direct relationship, try location_admins table
    const { data: adminLocations, error: adminError } = await supabase
      .from('location_admins')
      .select('locations(*)')
      .eq('user_id', userId);

    if (adminError) throw adminError;

    return adminLocations?.map(al => al.locations) || [];
  },

  async getLocationById(locationId: string): Promise<Location> {
    const { data, error } = await supabase
      .from('locations')
      .select(`
        *,
        customers:customer_profiles(*),
        mailboxes(*)
      `)
      .eq('id', locationId)
      .single();

    if (error) throw error;
    if (!data) throw new Error('Location not found');

    return data;
  },

  async getLocationStats(locationId: string): Promise<LocationStats> {
    const { data, error } = await supabase
      .rpc('get_location_stats', {
        p_location_id: locationId
      });

    if (error) throw error;
    if (!data) throw new Error('Failed to get location stats');

    return data;
  },

  async updateMailbox(id: string, data: any): Promise<void> {
    const { error } = await supabase
      .from('mailboxes')
      .update(data)
      .eq('id', id);

    if (error) throw error;
  }
};

2. React Component That Fetches and Displays Location Data

File: Locations.tsx

Note: The current code in this file uses hardcoded mock data for locations. If you want to use live Supabase data, you would typically call the service above (e.g., locationService.getLocationsByAdminId or similar) inside a React component with useEffect and useState.

import { Plus, Search, MapPin, Clock, Users, Package } from 'lucide-react';
import { classNames } from '../utils/classNames';

const locations = [
  {
    id: 1,
    name: 'Downtown Store',
    address: '123 Main St, Downtown',
    hours: '9:00 AM - 6:00 PM',
    staff: 5,
    status: 'open',
    mailboxes: 150,
    availableMailboxes: 23,
  },
  {
    id: 2,
    name: 'Westside Location',
    address: '456 West Ave, Westside',
    hours: '8:00 AM - 7:00 PM',
    staff: 4,
    status: 'open',
    mailboxes: 100,
    availableMailboxes: 15,
  },
  {
    id: 3,
    name: 'Eastside Branch',
    address: '789 East Blvd, Eastside',
    hours: '9:00 AM - 5:00 PM',
    staff: 3,
    status: 'closed',
    mailboxes: 75,
    availableMailboxes: 30,
  },
];

export function Locations() {
  return (
    <div className="space-y-8">
      <div className="sm:flex sm:items-center sm:justify-between">
        <h1 className="text-2xl font-semibold text-gray-900">Locations</h1>
        <div className="mt-3 sm:ml-4 sm:mt-0">
          <button
            type="button"
            className="inline-flex items-center rounded-md bg-indigo-600 px-3 py-2 text-sm font-semibold text-white shadow-sm hover:bg-indigo-500"
          >
            <Plus className="-ml-0.5 mr-1.5 h-5 w-5" />
            Add Location
          </button>
        </div>
      </div>
      {/* ...render locations... */}
    </div>
  );
}

If you want a live example of fetching and displaying locations from Supabase, let me know and I can provide a ready-to-use React component using the service above.

import { Plus, Search, MapPin, Clock, Users, Package } from 'lucide-react';
import { classNames } from '../utils/classNames';

const locations = [
{
id: 1,
name: 'Downtown Store',
address: '123 Main St, Downtown',
hours: '9:00 AM - 6:00 PM',
staff: 5,
status: 'open',
mailboxes: 150,
availableMailboxes: 23,
},
{
id: 2,
name: 'Westside Location',
address: '456 West Ave, Westside',
hours: '8:00 AM - 7:00 PM',
staff: 4,
status: 'open',
mailboxes: 100,
availableMailboxes: 15,
},
{
id: 3,
name: 'Eastside Branch',
address: '789 East Blvd, Eastside',
hours: '9:00 AM - 5:00 PM',
staff: 3,
status: 'closed',
mailboxes: 75,
availableMailboxes: 30,
},
];

export function Locations() {
return (

Locations

Add Location

{/* ...render locations... */}

);
}

This will be a paid gig, and yes I have RLS enabled.

Let's connect and see what is the error log and whats's the exact issue? let's connect over a quick call?
