## Pending 📋

### 7-11. Frontend Implementation

The following items require frontend development:

- React frontend with Mantine and TanStack Start
- Oranguru integration for grids and forms
- User login interface
- API key management UI
- User-level hooks and WhatsApp account management UI

## How to Use

### 1. Database Setup

```go
import "git.warky.dev/wdevs/whatshooked/pkg/storage"
import "git.warky.dev/wdevs/whatshooked/pkg/config"

// Initialize database
cfg := &config.DatabaseConfig{
    Type:     "postgres", // or "sqlite"
    Host:     "localhost",
    Port:     5432,
    Username: "whatshooked",
    Password: "password",
    Database: "whatshooked",
}

err := storage.Initialize(cfg)
if err != nil {
    log.Fatal(err)
}

// Run migrations
err = storage.AutoMigrate()
if err != nil {
    log.Fatal(err)
}

// Seed default data (creates admin user)
err = storage.SeedData(context.Background())
if err != nil {
    log.Fatal(err)
}
```

### 2. Start Web Server

```go
import "git.warky.dev/wdevs/whatshooked/pkg/webserver"

// Create server with JWT secret
server, err := webserver.NewServer("your-secret-key-here")
if err != nil {
    log.Fatal(err)
}

// Start server
log.Fatal(server.Start(":8825"))
```

### 3. API Usage Examples

**Login**:

```bash
curl -X POST http://localhost:8825/api/v1/auth/login \
  -H "Content-Type: application/json" \
  -d '{"username":"admin","password":"admin123"}'
```

**Create Hook** (with JWT):

```bash
curl -X POST http://localhost:8825/api/v1/hooks \
  -H "Authorization: Bearer YOUR_JWT_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{
    "name": "My Webhook",
    "url": "https://example.com/webhook",
    "method": "POST",
    "events": ["message.received"],
    "active": true
  }'
```

**Create API Key**:

```bash
curl -X POST http://localhost:8825/api/v1/api-keys \
  -H "Authorization: Bearer YOUR_JWT_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"name":"Production API Key"}'
```

**Use API Key**:

```bash
curl http://localhost:8825/api/v1/hooks \
  -H "Authorization: ApiKey YOUR_API_KEY"
```

## Security Features

1. **Multi-tenancy**: Users can only access their own resources (hooks, API keys, accounts)
2. **Role-based Access Control**: Admin, user, and viewer roles with hierarchical permissions
3. **JWT Authentication**: Secure token-based authentication with 24-hour expiry
4. **API Key Authentication**: Alternative authentication for programmatic access
5. **Password Hashing**: Bcrypt with default cost for secure password storage
6. **Ownership Verification**: All CRUD operations verify resource ownership
7. **Audit Trail**: EventLog table for tracking all operations

## Next Steps

To complete Phase 2, implement the frontend:

1. **Initialize Frontend Project**:

   ```bash
   npm create @tanstack/start@latest
   cd frontend
   npm install @mantine/core @mantine/hooks @mantine/notifications @mantine/form @mantine/datatable
   npm install @warkypublic/oranguru
   npm install @tanstack/react-query axios
   ```

2. **Create Components**:
   - Login page
   - Dashboard layout with navigation
   - User profile page
   - API key management page
   - Hook management page (with Oranguru DataTable)
   - WhatsApp account management page

3. **Integrate with API**:
   - Setup axios with JWT token interceptor
   - Create API client modules
   - Implement TanStack Query for data fetching
   - Add error handling and loading states

4. **Build and Deploy**:
   - Build frontend: `npm run build`
   - Serve static files through Go server
   - Configure reverse proxy if needed

## Using Oranguru

1. import { Gridler } from '../Gridler';

- Gridler is the grid component
- GlidlerAPIAdaptorForGoLangv2 is used to connect Gridler to RestHeadSpecAPI

```ts
const GridExample = () => {
const columns: GridlerColumns = [
    {
      Cell: (row) => {
        const process = `${
          row?.cql2?.length > 0
            ? '🔖'
            : row?.cql1?.length > 0
              ? '📕'
              : row?.status === 1
                ? '💡'
                : row?.status === 2
                  ? '🔒'
                  : '⚙️'
        } ${String(row?.id_process ?? '0')}`;

        return {
          data: process,
          displayData: process,
          status: row?.status,
        } as any;
      },
      id: 'id_process',
      title: 'RID',
      width: 100,
    },

    {
      id: 'process',
      title: 'Process',
      tooltip: (buffer) => {
        return `Process: ${buffer?.process}\nType: ${buffer?.processtype}\nStatus: ${buffer?.status}`;
      },
      width: 200,
    },
    {
      id: 'processtype',
      title: 'Type',
    },

    {
      disableSort: true,
      id: 'status',
      title: 'Status',
      width: 100,
    },
  ];


return (<Gridler
        columns={columns}
        height="100%"
        keyField="id_process"
        onChange={(v) => {
          //console.log('GridlerGoAPIExampleEventlog onChange', v);
          setValues(v);
        }}
        ref={ref}
        scrollToRowKey={selectRow ? parseInt(selectRow, 10) : undefined}
        searchStr={search}
        sections={{ ...sections, rightElementDisabled: false }}
        selectFirstRowOnMount={true}
        selectMode="row"
        title="Go API Example"
        uniqueid="gridtest"
        values={values}
      >
        <GlidlerAPIAdaptorForGoLangv2
          authtoken={apiKey}
          options={[{ type: 'preload', value: 'PRO' }]}
          //options={[{ type: 'fieldfilter', name: 'process', value: 'test' }]}
          url={`${apiUrl}/public/process`}
        />
        <Gridler.FormAdaptor
          changeOnActiveClick={true}
          descriptionField={'process'}
          onRequestForm={(request, data) => {
            console.log('Form requested', request, data);
            //Show form insert,update,delete
          }}
        />
      </Gridler>
      )
}
```

2. Former is a form wrapper that uses react-hook-form to handle forms.

```ts
import { TextInput } from '@mantine/core';
import { useUncontrolled } from '@mantine/hooks';
import { url } from 'inspector';
import { Controller } from 'react-hook-form';

import { TextInputCtrl, NativeSelectCtrl } from '../../FormerControllers';
import { InlineWrapper } from '../../FormerControllers/Inputs/InlineWrapper';
import NumberInputCtrl from '../../FormerControllers/Inputs/NumberInputCtrl';
import { Former } from '../Former';
import { FormerRestHeadSpecAPI } from '../FormerRestHeadSpecAPI';

export const ApiFormData = (props: {
  onChange?: (values: Record<string, unknown>) => void;
  primeData?: Record<string, unknown>;
  values?: Record<string, unknown>;
}) => {
  const [values, setValues] = useUncontrolled<Record<string, unknown>>({
    defaultValue: { authToken: '', url: '', ...props.primeData },
    finalValue: { authToken: '', url: '', ...props.primeData },
    onChange: props.onChange,
    value: props.values,
  });

  return (
    <Former
      disableHTMlForm
      id="api-form-data"
      layout={{ saveButtonTitle: 'Save URL Parameters' }}
      onAPICall={FormerRestHeadSpecAPI({
        authToken: authToken,
        url: url,
      })}
      onChange={setValues}
      primeData={props.primeData}
      request="update"
      uniqueKeyField="id"
      values={values}
    >
      <TextInputCtrl label="Test" name="test" />
      <NumberInputCtrl label="AgeTest" name="age" />
      <InlineWrapper label="Select One" promptWidth={200}>
        <NativeSelectCtrl data={['One', 'Two', 'Three']} name="option1" />
      </InlineWrapper>
      {/* Controllers can be use but we prefer to use the build TextInputCtrl and such for better integration with Former's state management and validation. However, you can also use the Controller component from react-hook-form to integrate custom inputs like this: */}
      <Controller
        name="url"
        render={({ field }) => <TextInput label="URL" type="url" {...field} />}
      />
      <Controller
        name="authToken"
        render={({ field }) => <TextInput label="Auth Token" type="password" {...field} />}
      />
    </Former>
  );
};
```

3. Controls TextInputCtrl,NumberInputCtrl,NativeSelectCtrl and InlineWrapper

- InlineWrapper is used to display the title on the left and control to the right.

```ts
const Renderable = () => {
  return (
    <Former>
      <Stack h="100%" mih="400px" miw="400px" w="100%">
        <TextInputCtrl label="Test" name="test" />
        <NumberInputCtrl label="AgeTest" name="age" />
        <InlineWrapper label="Select One" promptWidth={200}>
            <NativeSelectCtrl data={["One","Two","Three"]} name="option1"/>
        </InlineWrapper>
      </Stack>
    </Former>
  );
};
```

4. Boxer is an advanced multi select control with infinite query lookap features for an API.

```ts

// Server-Side Example (Simulated)
export const ServerSide: Story = {
  render: () => {
    const [value, setValue] = useState<null | string>(null);

    // Simulate server-side API call
    const handleAPICall = async (params: {
      page: number;
      pageSize: number;
      search?: string;
    }): Promise<{ data: Array<BoxerItem>; total: number }> => {
      // Simulate network delay
      await new Promise((resolve) => setTimeout(resolve, 500));

      // Filter based on search
      let filteredData = [...sampleData];
      if (params.search) {
        filteredData = filteredData.filter((item) =>
          item.label.toLowerCase().includes(params.search!.toLowerCase())
        );
      }

      // Paginate
      const start = params.page * params.pageSize;
      const end = start + params.pageSize;
      const paginatedData = filteredData.slice(start, end);

      return {
        data: paginatedData,
        total: filteredData.length,
      };
    };

    return (
      <div style={{ width: 300 }}>
        <Boxer
          clearable
          dataSource="server"
          label="Favorite Fruit (Server-side)"
          onAPICall={handleAPICall}
          onChange={setValue}
          pageSize={10}
          placeholder="Select a fruit (Server-side)"
          searchable
          value={value}
        />
        <div style={{ marginTop: 20 }}>
          <strong>Selected Value:</strong> {value ?? 'None'}
        </div>
      </div>
    );
  },
};

// Multi-Select Example
export const MultiSelect: Story = {
  render: () => {
    const [value, setValue] = useState<Array<string>>([]);

    return (
      <div style={{ width: 300 }}>
        <Boxer
          clearable
          data={sampleData}
          dataSource="local"
          label="Favorite Fruits"
          multiSelect
          onChange={setValue}
          placeholder="Select fruits"
          searchable
          value={value}
        />
        <div style={{ marginTop: 20 }}>
          <strong>Selected Values:</strong>{' '}
          {value.length > 0 ? value.join(', ') : 'None'}
        </div>
      </div>
    );
  },
};

```
