RainfallJS

Build Status Tests npm version License: MIT npm downloads

A comprehensive data integration solution for React and Next.js applications that provides automated, secure, and reliable data handling.

About the Name

RainfallJS: Just as rain naturally flows from clouds down to nourish plants below, data "rains" down from your data sources to feed your React components. The name reflects our philosophy that data flow should be as natural, reliable, and effortless as rainfall - distributed exactly where it's needed without manual intervention. This project aims to be guided by principles that guide engineering like shown here.

Features

  • 🔄 Automated Data Flow - Effortlessly connect components to data sources
  • 🔒 Security Built-in - Secure data handling with authentication and validation
  • 🚀 Next.js Integration - Special features for Next.js applications
  • Performance Optimized - Smart caching and minimal re-renders
  • 🧩 Component Agnostic - Works with both functional and class components
  • 🎛️ Component Library Integration - Automatic mapping to UI component libraries

Installation

npm install @morf_engineering/rainfalljs

# or if you use yarn
yarn add @morf_engineering/rainfalljs

Basic Usage

Simple Data Provider

import { DataProvider, useData } from '@morf_engineering/rainfalljs';

// Your component that needs data
const UserProfile = () => {
  const { data, loading, error } = useData();
  
  if (loading) return <div>Loading...</div>;
  if (error) return <div>Error: {error}</div>;
  
  return (
    <div>
      <h1>{data.name}</h1>
      <p>Email: {data.email}</p>
    </div>
  );
};

// Wrap with DataProvider
const App = () => (
  <DataProvider source="/api/user">
    <UserProfile />
  </DataProvider>
);

Next.js Integration

import { NextDataProvider } from '@morf_engineering/rainfalljs';

// Your Next.js page
export default function Dashboard({ initialData }) {
  // Route-based data mapping
  const routeMapping = {
    '/dashboard': '/api/dashboard-data',
    '/dashboard/users': '/api/users',
    '/dashboard/analytics': '/api/analytics'
  };
  
  return (
    <NextDataProvider 
      routeMapping={routeMapping}
      defaultSource="/api/default"
      initialData={initialData}
    >
      <DashboardContent />
    </NextDataProvider>
  );
}

// Server-side data fetching
import { withServerSideData } from '@morf_engineering/rainfalljs';

export const getServerSideProps = withServerSideData(
  async (context) => {
    // Your existing getServerSideProps logic
    return { props: { otherProp: 'value' } };
  },
  {
    source: '/api/dashboard-data'
  }
);

Creating API Routes in Next.js

// pages/api/users.js
import { createApiRoute } from '@morf_engineering/rainfalljs';

export default createApiRoute(
  async (req, res) => {
    // Fetch users from database
    const users = await db.getUsers();
    return users;
  },
  {
    requireAuth: true,
    exposeErrors: process.env.NODE_ENV !== 'production'
  }
);

Component Library Integration

RainfallJS provides automatic data mapping to UI component libraries like Material-UI and Ant Design:

import { DataProvider, withComponentData, registerMUIComponents } from '@morf_engineering/rainfalljs';
import { DataGrid } from '@mui/x-data-grid';

// Register Material UI components (do this once in your app)
registerMUIComponents();

// Create a mapped component
const UsersGrid = withComponentData(DataGrid, 'mui', 'DataGrid');

// Use it with your data provider
function UsersList() {
  return (
    <DataProvider source="/api/users">
      <UsersGrid />
    </DataProvider>
  );
}

Using Hooks Pattern

import { useData, useComponentData } from '@morf_engineering/rainfalljs';
import { Table } from 'antd';

function UserTable() {
  // Get the component props automatically mapped from your data
  const { mappedProps } = useComponentData('antd', 'Table', {
    headers: {
      userId: 'User ID',
      fullName: 'Full Name'
    }
  });
  
  return <Table {...mappedProps} />;
}
### Radix UI Integration

RainfallJS provides seamless integration with Radix UI's unstyled, accessible components:

```jsx
import { DataProvider, registerRadixComponents, useComponentData } from '@morf_engineering/rainfalljs';
import * as Select from '@radix-ui/react-select';

// Register Radix UI component mappings (do this once in your app)
registerRadixComponents();

// Example: Radix UI Select with automatic data mapping
function UserSelect() {
  const { mappedProps, loading, error } = useComponentData('radix', 'Select', {
    valueField: 'id',
    labelField: 'name'
  });
  
  if (loading) return <div>Loading...</div>;
  
  return (
    <Select.Root>
      <Select.Trigger>
        <Select.Value placeholder="Select a user" />
        <Select.Icon />
      </Select.Trigger>
      
      <Select.Portal>
        <Select.Content>
          <Select.Viewport>
            {mappedProps.items.map((item) => (
              <Select.Item key={item.value} value={item.value}>
                <Select.ItemText>{item.label}</Select.ItemText>
                <Select.ItemIndicator />
              </Select.Item>
            ))}
          </Select.Viewport>
        </Select.Content>
      </Select.Portal>
    </Select.Root>
  );
}

// Use it with your data provider
function UserSelection() {
  return (
    <DataProvider source="/api/users">
      <UserSelect />
    </DataProvider>
  );
}

RainfallJS handles the complexities of Radix UI's compound component pattern, automatically mapping your data to the appropriate format for Radix components like Select, Dialog, and Tabs.

Let me create a component mapping integration for shadcn/ui, which is built on top of Radix UI but with pre-styled components and a more cohesive API:

// examples/component-mapping/shadcn-example.js
import React from 'react';
import { DataProvider } from '@morf_engineering/rainfalljs';
import { registerComponentLibrary, withComponentData, useComponentData } from '@morf_engineering/rainfalljs';
import { 
  Select, 
  SelectContent, 
  SelectItem, 
  SelectTrigger, 
  SelectValue 
} from "@/components/ui/select";
import { 
  Table, 
  TableBody, 
  TableCaption, 
  TableCell, 
  TableHead, 
  TableHeader, 
  TableRow 
} from "@/components/ui/table";
import { 
  Card, 
  CardContent, 
  CardDescription, 
  CardFooter, 
  CardHeader, 
  CardTitle 
} from "@/components/ui/card";
import { Tabs, TabsContent, TabsList, TabsTrigger } from "@/components/ui/tabs";

// Register shadcn/ui component mappings
export const registerShadcnComponents = () => {
  registerComponentLibrary('shadcn', {
    // Select mapping
    Select: (data, props, options) => {
      const { valueField = 'value', labelField = 'label' } = options;
      
      let items = [];
      if (Array.isArray(data)) {
        items = data.map(item => ({
          value: item[valueField] || item.id || item.value,
          label: item[labelField] || item.name || item.label
        }));
      }
      
      return {
        items,
        placeholder: options.placeholder || "Select an option",
        defaultValue: options.defaultValue || items[0]?.value,
        ...options.selectOptions
      };
    },
    
    // Table mapping
    Table: (data, props, options) => {
      // Extract column definitions
      let columns = [];
      if (data && data.length > 0) {
        columns = Object.keys(data[0]).map(key => ({
          id: key,
          header: options.headers?.[key] || key.charAt(0).toUpperCase() + key.slice(1).replace(/([A-Z])/g, ' $1'),
          accessorKey: key,
          ...options.columnOptions?.[key]
        }));
      }
      
      return {
        data: Array.isArray(data) ? data : [],
        columns: options.columns || columns,
        caption: options.caption || "",
        ...options.tableOptions
      };
    },
    
    // Card mapping
    Card: (data, props, options) => {
      return {
        title: data?.title || options.defaultTitle || 'Card Title',
        description: data?.description || options.defaultDescription || '',
        content: data?.content || data,
        footer: data?.footer || options.footer || null,
        ...options.cardOptions
      };
    },
    
    // Tabs mapping
    Tabs: (data, props, options) => {
      let tabs = [];
      if (Array.isArray(data)) {
        tabs = data.map(item => ({
          value: item[options.valueField || 'id'] || item.id || item.value,
          label: item[options.labelField || 'title'] || item.title || item.label,
          content: item[options.contentField || 'content'] || item.content || item.description
        }));
      }
      
      return {
        tabs,
        defaultValue: data?.[0]?.[options.valueField || 'id'] || 'tab1',
        ...options.tabsOptions
      };
    }
  });
};

// Register the components
registerShadcnComponents();

// Example: shadcn/ui Select with automatic data mapping
const UserSelect = () => {
  const { mappedProps, loading, error } = useComponentData('shadcn', 'Select', {
    valueField: 'id',
    labelField: 'name',
    placeholder: "Select a user"
  });
  
  if (loading) return <div>Loading...</div>;
  if (error) return <div>Error: {error}</div>;
  
  return (
    <Select defaultValue={mappedProps.defaultValue} {...mappedProps.selectOptions}>
      <SelectTrigger>
        <SelectValue placeholder={mappedProps.placeholder} />
      </SelectTrigger>
      <SelectContent>
        {mappedProps.items.map((item) => (
          <SelectItem key={item.value} value={item.value}>
            {item.label}
          </SelectItem>
        ))}
      </SelectContent>
    </Select>
  );
};

// Example: shadcn/ui Table with data mapping
const UsersTable = () => {
  const { mappedProps, loading, error } = useComponentData('shadcn', 'Table', {
    headers: {
      id: 'ID',
      name: 'Full Name',
      email: 'Email Address',
      role: 'User Role'
    },
    caption: "List of system users"
  });
  
  if (loading) return <div>Loading...</div>;
  if (error) return <div>Error: {error}</div>;
  
  return (
    <Table>
      {mappedProps.caption && <TableCaption>{mappedProps.caption}</TableCaption>}
      <TableHeader>
        <TableRow>
          {mappedProps.columns.map((column) => (
            <TableHead key={column.id}>{column.header}</TableHead>
          ))}
        </TableRow>
      </TableHeader>
      <TableBody>
        {mappedProps.data.map((row) => (
          <TableRow key={row.id}>
            {mappedProps.columns.map((column) => (
              <TableCell key={`${row.id}-${column.id}`}>
                {row[column.accessorKey]}
              </TableCell>
            ))}
          </TableRow>
        ))}
      </TableBody>
    </Table>
  );
};

// Example: shadcn/ui Card with data mapping
const UserCard = withComponentData(
  ({ title, description, content, footer }) => (
    <Card>
      <CardHeader>
        <CardTitle>{title}</CardTitle>
        <CardDescription>{description}</CardDescription>
      </CardHeader>
      <CardContent>
        {typeof content === 'object' ? (
          <div>
            <p><strong>Name:</strong> {content.name}</p>
            <p><strong>Email:</strong> {content.email}</p>
            <p><strong>Role:</strong> {content.role}</p>
          </div>
        ) : (
          <p>{content}</p>
        )}
      </CardContent>
      {footer && (
        <CardFooter>
          {footer}
        </CardFooter>
      )}
    </Card>
  ),
  'shadcn',
  'Card',
  {
    defaultTitle: 'User Profile',
    defaultDescription: 'User details and information',
    footer: <button className="btn btn-primary">Edit Profile</button>
  }
);

// Example: shadcn/ui Tabs with data mapping
const ProjectTabs = () => {
  const { mappedProps, loading, error } = useComponentData('shadcn', 'Tabs', {
    valueField: 'id',
    labelField: 'name',
    contentField: 'description'
  });
  
  if (loading) return <div>Loading...</div>;
  if (error) return <div>Error: {error}</div>;
  
  return (
    <Tabs defaultValue={mappedProps.defaultValue}>
      <TabsList>
        {mappedProps.tabs.map(tab => (
          <TabsTrigger key={tab.value} value={tab.value}>
            {tab.label}
          </TabsTrigger>
        ))}
      </TabsList>
      {mappedProps.tabs.map(tab => (
        <TabsContent key={tab.value} value={tab.value}>
          {tab.content}
        </TabsContent>
      ))}
    </Tabs>
  );
};

// Complete example with DataProvider
const Dashboard = () => {
  const users = [
    { id: '1', name: 'John Doe', email: 'john@example.com', role: 'Admin' },
    { id: '2', name: 'Jane Smith', email: 'jane@example.com', role: 'Developer' },

          <ProjectTabs />
        </DataProvider>
      </div>
    </div>
  );
};

export default Dashboard;
### shadcn/ui Integration

RainfallJS provides elegant integration with shadcn/ui's beautifully designed components:

```jsx
import { DataProvider, registerShadcnComponents, useComponentData } from '@morf_engineering/rainfalljs';
import { 
  Table, 
  TableBody, 
  TableCaption, 
  TableCell, 
  TableHead, 
  TableHeader, 
  TableRow 
} from "@/components/ui/table";

// Register shadcn components (do this once in your app)
registerShadcnComponents();

// Create a data-aware table with automatic mapping
function UsersTable() {
  const { mappedProps, loading, error } = useComponentData('shadcn', 'Table', {
    headers: {
      id: 'ID',
      name: 'Full Name',
      email: 'Email Address'
    },
    caption: "System Users"
  });
  
  if (loading) return <div>Loading...</div>;
  
  return (
    <Table>
      <TableCaption>{mappedProps.caption}</TableCaption>
      <TableHeader>
        <TableRow>
          {mappedProps.columns.map((column) => (
            <TableHead key={column.id}>{column.header}</TableHead>
          ))}
        </TableRow>
      </TableHeader>
      <TableBody>
        {mappedProps.data.map((row) => (
          <TableRow key={row.id}>
            {mappedProps.columns.map((column) => (
              <TableCell key={`${row.id}-${column.id}`}>
                {row[column.accessorKey]}
              </TableCell>
            ))}
          </TableRow>
        ))}
      </TableBody>
    </Table>
  );
}

// Use it with your data
function UsersList() {
  return (
    <DataProvider source="/api/users">
      <UsersTable />
    </DataProvider>
  );
}

RainfallJS supports all major shadcn/ui components including Select, Table, Card, and Tabs, automatically handling the complex component composition patterns for you.


This integration leverages the componentized nature of shadcn/ui while providing automatic data mapping to make it extremely simple to connect your data to the UI.


## Advanced Usage

### Custom Data Sources

```jsx
import { createDataSource, DataProvider } from '@morf_engineering/rainfalljs';

// Create a custom data source
const userDataSource = createDataSource({
  endpoint: 'https://api.example.com/users',
  method: 'GET',
  params: { limit: 10 }
});

// Use the custom data source
const App = () => (
  <DataProvider 
    source={userDataSource}
    options={{
      headers: {
        'Authorization': `Bearer ${token}`
      }
    }}
  >
    <UserList />
  </DataProvider>
);

Data Transformation

<DataProvider
  source="/api/data"
  options={{
    transform: (data) => {
      // Transform data before it reaches components
      return data.map(item => ({
        ...item,
        fullName: `${item.firstName} ${item.lastName}`,
        createdAt: new Date(item.createdAt)
      }));
    }
  }}
>
  <MyComponent />
</DataProvider>

With Class Components

import { withData } from '@morf_engineering/rainfalljs';

class UserProfile extends React.Component {
  render() {
    const { data, loading, error } = this.props;
    
    if (loading) return <div>Loading...</div>;
    if (error) return <div>Error: {error}</div>;
    
    return (
      <div>
        <h1>{data.name}</h1>
        <p>Email: {data.email}</p>
      </div>
    );
  }
}

// Connect the component to data
export default withData(UserProfile);

The Value of RainfallJS vs. Vanilla Context API

When developers evaluate a new package, they often ask: "Why should I use this instead of what I already know?" Let's compare using RainfallJS to implementing data management with vanilla React Context API:

Using Vanilla React Context API

// 1. Create a context
const UserContext = React.createContext(null);

// 2. Create a provider component with data fetching logic
function UserProvider({ children }) {
  const [data, setData] = useState(null);
  const [loading, setLoading] = useState(true);
  const [error, setError] = useState(null);
  
  useEffect(() => {
    async function fetchData() {
      try {
        setLoading(true);
        const response = await fetch('/api/users');
        if (!response.ok) throw new Error('Failed to fetch');
        const result = await response.json();
        setData(result);
      } catch (err) {
        setError(err.message);
      } finally {
        setLoading(false);
      }
    }
    
    fetchData();
  }, []);
  
  return (
    <UserContext.Provider value={{ data, loading, error }}>
      {children}
    </UserContext.Provider>
  );
}

// 3. Create a custom hook
function useUserData() {
  const context = useContext(UserContext);
  if (!context) {
    throw new Error('useUserData must be used within a UserProvider');
  }
  return context;
}

// 4. Implement in components
function UserProfile() {
  const { data, loading, error } = useUserData();
  
  if (loading) return <div>Loading...</div>;
  if (error) return <div>Error: {error}</div>;
  
  return <div>{data.name}</div>;
}

// 5. Usage
function App() {
  return (
    <UserProvider>
      <UserProfile />
    </UserProvider>
  );
}

Using RainfallJS

import { DataProvider, useData } from '@morf_engineering/rainfalljs';

// 1. Component implementation
function UserProfile() {
  const { data, loading, error } = useData();
  
  if (loading) return <div>Loading...</div>;
  if (error) return <div>Error: {error}</div>;
  
  return <div>{data.name}</div>;
}

The Value RainfallJS Adds

  1. Eliminates Boilerplate: With vanilla Context, you need to create a context, provider, fetch logic, state management, and custom hooks for each data source in your application. RainfallJS handles all this with a single reusable component.

  2. Standardized Error Handling: Consistent error management across all data sources without duplicating try/catch logic.

  3. Flexible Data Sources: RainfallJS accepts API endpoints, functions, or static data, with the same consistent interface.

  4. Route-Based Data in Next.js: Automatic data fetching based on current route, saving dozens of lines of code per page.

  5. Component Library Integration: Automatic mapping of data to UI component props, eliminating tedious data transformation code.

  6. Security Built-In: Authentication headers, data validation, and other security features that you'd need to implement manually with Context.

  7. Production-Ready: Implements best practices for performance, caching, and server-side rendering that would take significant effort to build correctly with Context API.

  8. Consistent API: No need to create and remember different context hook names for different data types.

For a real-world application with 10+ data sources and 20+ components, RainfallJS can eliminate hundreds of lines of repetitive context creation and data fetching code while providing more features and better reliability.

FAQ

What is RainfallJS?

RainfallJS is a specialized data integration solution for React and Next.js applications that makes it easy to fetch, manage, and distribute data across your components with minimal boilerplate.

Does RainfallJS use React's Context API?

Yes, RainfallJS is built on top of React's Context API. Rather than replacing Context, it enhances it with automated data fetching, transformation, validation, and error handling capabilities specifically designed for component data management.

What problem does RainfallJS solve?

RainfallJS solves several common issues in React/Next.js applications:

  1. Repetitive data fetching logic - No need to write the same fetch/state management code for every data source
  2. Prop drilling - Access data anywhere in your component tree without passing props through multiple layers
  3. Loading & error states - Unified handling of loading indicators and error messages
  4. Next.js specific challenges - Integration with SSR and route-based data fetching
  5. Security concerns - Built-in authentication header management and data validation

How is this different from Redux, MobX, or React Query?

  • Redux/MobX: RainfallJS is more lightweight and focused specifically on component data needs rather than global application state.
  • React Query: While React Query is excellent for data fetching, RainfallJS provides a more unified context-based approach for data sharing across components and includes Next.js-specific optimizations.
  • SWR: Similar to React Query, SWR focuses on data fetching and caching. RainfallJS provides a more complete data distribution system with both hooks and HOCs.

Can I use RainfallJS with class components?

Yes! While many modern data libraries only work with hooks, RainfallJS supports both functional components (via the useData hook) and class components (via the withData HOC).

Does RainfallJS work with Server-Side Rendering (SSR)?

Absolutely. RainfallJS has specific features for Next.js that support SSR through the withServerSideData higher-order component, ensuring your data is available during server rendering.

Can I transform or validate data before it reaches my components?

Yes, RainfallJS allows you to provide transformation and validation functions as options:

<DataProvider 
  source="/api/data"
  options={{
    transform: (data) => {
      // Transform data before it reaches components
      return data.map(item => ({
        ...item,
        fullName: `${item.firstName} ${item.lastName}`
      }));
    },
    validate: (data) => {
      // Validate data structure
      return Array.isArray(data) && data.length > 0;
    }
  }}
>
  <YourComponent />
</DataProvider>

Is RainfallJS secure?

RainfallJS includes built-in security features, including:

  • Authentication header management
  • Data validation before rendering
  • API route protection helpers for Next.js
  • Error sanitization to prevent leaking sensitive information

How can I contribute to RainfallJS?

Contributions are welcome! Please feel free to submit a pull request or open an issue on our GitHub repository.

Can I use RainfallJS in production?

Yes, RainfallJS is designed for production use in React and Next.js applications. The package is optimized for performance and has minimal dependencies.

Can I develop complex apps with RainfallJS?

RainfallJS could certainly be used to build complex applications, but with a different architectural approach than Redux for example. Here's how you could build complex apps with RainfallJS:

Composable Data Providers: Users can nest multiple DataProviders for different sections of the application, creating a hierarchy of data sources that maps to the component structure. Domain-Specific Providers: Each feature area could have its own DataProvider with specific transformations and validations, allowing separation of concerns. Hybrid Approach: RainfallJS could handle all the data fetching and distribution needs, while using simpler state management (like useReducer) for UI state and interactions. Cross-Provider Communication: For interactions between data domains, users could implement custom data sources that access and combine data from multiple endpoints.

The key difference is philosophical:

Redux centralizes all state in a single store with explicit actions RainfallJS distributes data management closer to where it's used, following React's component model

For many complex applications, RainfallJS's approach may actually be more maintainable because it:

Keeps data concerns closer to the components that need them Results in more modular, decoupled code Aligns better with React's component-based architecture

The trade-off is that RainfallJS doesn't offer some of Redux's specialized tools like time-travel debugging or the Redux DevTools. However, for most applications focused on data fetching and component integration, these tools aren't essential, and the simplicity benefits outweigh this loss.
