​
CRUD Package

The @repo/crud package extends the data package with additional features like permissions, auditing, and plugins. It provides a comprehensive framework for building CRUD (Create, Read, Update, Delete) operations in your application.

​
Features

  • Enhanced CRUD Operations: Built on top of the data package with additional functionality
  • Permissions System: Fine-grained access control for CRUD operations
  • Audit Logging: Track changes to data with detailed audit logs
  • Plugin Architecture: Extend functionality with custom plugins
  • React Integration: Hooks and components for seamless React integration
  • Internationalization: Support for multiple languages
  • Customizable UI: Flexible UI components for building admin interfaces

​
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/crud

​
Package Structure

The CRUD package is organized into several subpackages:
  • Engine: Core CRUD functionality built on top of data providers
  • Hooks: React hooks for CRUD operations
  • UI: UI components for CRUD operations
  • Permissions: Access control for CRUD operations
  • Plugins: Extensibility points for CRUD operations
  • Audit: Tracking changes to data

​
Dependencies

The CRUD package depends on the following packages:
  • @repo/data: Core data management and provider packages
  • next-intl: Internationalization support

​
Basic Usage

​
Creating a CRUD Engine

import { engine } from '@repo/crud';
import { providers } from '@repo/data';

// Create a data provider
const dataProvider = providers.supabase.createProvider({
  url: process.env.SUPABASE_URL,
  key: process.env.SUPABASE_KEY
});

// Create a CRUD engine
const crudEngine = engine.createCrudEngine({
  dataProvider,
  enableAudit: true,
  enablePermissions: true,
  plugins: [],
  defaultLocale: 'en',
  supportedLocales: ['en', 'fr', 'de', 'es', 'tr']
});

​
Performing CRUD Operations

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

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

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

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

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

​
Using React Hooks

import { hooks } from '@repo/crud';

function UserList() {
  // Fetch a list of users
  const { data, loading, error, refetch } = hooks.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 (
    <div>
      <button onClick={() => refetch()}>Refresh</button>
      <ul>
        {data.map(user => (
          <li key={user.id}>{user.name}</li>
        ))}
      </ul>
    </div>
  );
}

​
Using UI Components

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

function UserManagement() {
  return (
    <ui.CrudProvider>
      <ui.ResourceList
        resource="users"
        columns={[
          { field: 'id', headerName: 'ID' },
          { field: 'name', headerName: 'Name' },
          { field: 'email', headerName: 'Email' },
          { field: 'role', headerName: 'Role' }
        ]}
        actions={['view', 'edit', 'delete']}
        pagination
        sorting
        filtering
      />
    </ui.CrudProvider>
  );
}

​
Core Concepts

​
CRUD Engine

The CRUD Engine is the core of the package, providing enhanced CRUD operations with support for plugins, permissions, and auditing. It wraps a data provider from the @repo/data package and adds additional functionality. 
interface CrudEngineOptions {
  /** The data provider to use */
  dataProvider: CrudProvider;
  /** Enable auditing of operations */
  enableAudit?: boolean;
  /** Enable permissions checking */
  enablePermissions?: boolean;
  /** Plugins to use */
  plugins?: CrudPlugin[];
  /** Default locale for internationalization */
  defaultLocale?: string;
  /** Supported locales for internationalization */
  supportedLocales?: string[];
}

​
Plugin System

The plugin system allows you to extend the functionality of the CRUD engine with custom hooks that run before and after CRUD operations: 
interface CrudPlugin {
  /** Unique name of the plugin */
  name: string;
  /** Plugin initialization function */
  initialize: (engine: CrudEngine) => void;
  /** Hooks for different CRUD operations */
  hooks?: {
    beforeGetList?: (params: GetListParams) => GetListParams;
    afterGetList?: (result: any, params: GetListParams) => any;
    beforeGetOne?: (params: GetOneParams) => GetOneParams;
    afterGetOne?: (result: any, params: GetOneParams) => any;
    beforeCreate?: (params: CreateParams) => CreateParams;
    afterCreate?: (result: any, params: CreateParams) => any;
    beforeUpdate?: (params: UpdateParams) => UpdateParams;
    afterUpdate?: (result: any, params: UpdateParams) => any;
    beforeDelete?: (params: DeleteParams) => DeleteParams;
    afterDelete?: (result: any, params: DeleteParams) => any;
  };
}

​
Permissions System

The permissions system provides fine-grained access control for CRUD operations, allowing you to define who can perform which operations on which resources: 
interface PermissionsProvider {
  getPermissions: (user: any) => Promise<ResourcePermissions>;
}

interface ResourcePermissions {
  [resource: string]: {
    read: boolean | ((user: any, resource: any) => boolean);
    create: boolean | ((user: any, data: any) => boolean);
    update: boolean | ((user: any, resource: any, data: any) => boolean);
    delete: boolean | ((user: any, resource: any) => boolean);
  };
}

​
Audit System

The audit system tracks changes to data, recording who made what changes and when: 
interface AuditProvider {
  logAudit: (auditLog: AuditLog) => Promise<void>;
}

interface AuditLog {
  timestamp: Date;
  user: any;
  action: 'create' | 'update' | 'delete';
  resource: string;
  resourceId: string;
  data?: any;
  previousData?: any;
}

​
Environment Variables

The CRUD package may use the following environment variables:
VariableDescriptionRequired
NEXT_PUBLIC_DEFAULT_LOCALEDefault locale for internationalizationNo (defaults to ‘en’)
NEXT_PUBLIC_SUPPORTED_LOCALESComma-separated list of supported localesNo (defaults to [‘en’])
