​
Data Layer

The @repo/data package provides a comprehensive solution for data operations with a standardized interface across different data sources. It serves as the foundation for all data-related functionality in the zopio framework.

​
Features

  • Unified Interface: Consistent API across all data sources
  • Multiple Providers: Support for Supabase, Firebase, REST, GraphQL, and more
  • Type Safety: Full TypeScript support with comprehensive type definitions
  • React Integration: Hooks and components for seamless React integration
  • Schema Validation: Built-in schema definition and validation
  • Extensibility: Plugin architecture for custom functionality
  • Optimized Performance: Efficient data fetching and caching strategies

​
Installation

This package is part of the zopio monorepo and is available to all applications in the workspace. 
# If you're adding it to a new package in the monorepo
pnpm add @repo/data

​
Package Structure

The data package is organized into three main subpackages:
  • Base: Core types, utilities, and base interfaces
  • Providers: Data providers that implement the CrudProvider interface
  • UI: React components and hooks for working with data

​
Basic Usage

​
Creating a Data Provider

import { base, providers } from '@repo/data';

// Create a Supabase provider
const dataProvider = base.createDataProvider({
  type: 'supabase',
  config: {
    url: process.env.SUPABASE_URL,
    key: process.env.SUPABASE_KEY,
  }
});

// Or use the provider-specific factory
const supabaseProvider = providers.supabase.createProvider({
  url: process.env.SUPABASE_URL,
  key: process.env.SUPABASE_KEY
});

​
Performing CRUD Operations

// Get a list of resources
const { data, total } = await dataProvider.getList({
  resource: 'users',
  pagination: { page: 1, perPage: 10 },
  sort: { field: 'createdAt', order: 'desc' },
  filter: { role: 'admin' }
});

// Get a single resource
const { data: user } = await dataProvider.getOne({
  resource: 'users',
  id: '123'
});

// Create a resource
const { data: newUser } = await dataProvider.create({
  resource: 'users',
  data: { name: 'John Doe', email: 'john@example.com' }
});

// Update a resource
const { data: updatedUser } = await dataProvider.update({
  resource: 'users',
  id: '123',
  data: { name: 'John Smith' }
});

// Delete a resource
const { data: deletedUser } = await dataProvider.delete({
  resource: 'users',
  id: '123'
});

​
Using React Hooks

import { ui } from '@repo/data';

function UserList() {
  // Fetch a list of users
  const { data, loading, error } = ui.useGetList('users', {
    pagination: { page: 1, perPage: 10 },
    sort: { field: 'createdAt', order: 'desc' }
  });

  if (loading) return <div>Loading...</div>;
  if (error) return <div>Error: {error.message}</div>;

  return (
    <ul>
      {data.map(user => (
        <li key={user.id}>{user.name}</li>
      ))}
    </ul>
  );
}

​
Using UI Components

import { ui } from '@repo/data';

function UserManagement() {
  return (
    <ui.DataProvider>
      <ui.DataList
        resource="users"
        columns={[
          { field: 'id', headerName: 'ID' },
          { field: 'name', headerName: 'Name' },
          { field: 'email', headerName: 'Email' }
        ]}
        pagination
        sorting
        filtering
      />
    </ui.DataProvider>
  );
}
