Admin Panel Builder

Current Architecture (2026)

Layout Pattern

All admin pages now use the SidebarProvider + AppSidebar + AdminHeader pattern:

import { SidebarProvider } from "@/components/ui/sidebar";
import { AppSidebar } from "@/components/AppSidebar";
import AdminHeader from "@/components/admin/AdminHeader";

return (
  <SidebarProvider>
    <div className="min-h-screen flex w-full bg-background">
      <AppSidebar onNavigateToContinueAudio={() => {}} onNavigateToContinueText={() => {}} />
      <main className="flex-1 overflow-auto">
        <AdminHeader
          title="Page Title"
          icon={<Icon className="h-6 w-6 text-primary" />}
          showBackButton={true}
        />
        <div className="p-6">
          {/* Content */}
        </div>
      </main>
    </div>
  </SidebarProvider>
);

Authentication Pattern

Use @shared-auth/hooks/useUserRole from the shared package:

import { useUserRole } from "@shared-auth/hooks/useUserRole";

const { isAdmin } = useUserRole();

if (!isAdmin) {
  return (
    <div className="flex items-center justify-center min-h-screen">
      <p className="text-muted-foreground">Sinulla ei ole oikeuksia tähän sivuun.</p>
    </div>
  );
}

Import Patterns

// UI components from @ui aliases
import { Button } from "@ui/button";
import { Card, CardContent, CardDescription, CardHeader, CardTitle } from "@ui/card";
import { Tabs, TabsContent, TabsList, TabsTrigger } from "@ui/tabs";

// Shared auth from @shared-auth
import { useUserRole } from "@shared-auth/hooks/useUserRole";

// Local imports with @/
import AdminHeader from "@/components/admin/AdminHeader";
import { supabase } from "@/integrations/supabase/client";

Existing Admin Pages Structure

Dashboard (AdminDashboardPage.tsx)

• Central hub with overview cards
• Grid layout with clickable admin cards
• Stats overview widget with quick metrics
• Uses lucide-react icons (Bot, Users, Video, etc.)
• Each card has: title, description, icon, path, stats, isLoading

Specialized Admin Pages

• AdminAIPage.tsx - AI management with tabs (usage, prompts, features, pricing)
• AdminAudioPage.tsx - Audio/TTS management
• AdminAuthTokensPage.tsx - Authentication and API tokens
• AdminTopicsPage.tsx - Topic management and translations
• AdminUsersPage.tsx - User and role management
• AdminTranslationsPage.tsx - Term translation cache
• AdminVideoPage.tsx - Video series and clips
• AdminWidgetAnalyticsPage.tsx - Widget usage statistics

Creating New Admin Pages

Step 1: Create Page Component

// apps/raamattu-nyt/src/pages/AdminExamplePage.tsx

import { useUserRole } from "@shared-auth/hooks/useUserRole";
import { Card, CardContent, CardDescription, CardHeader, CardTitle } from "@ui/card";
import { Tabs, TabsContent, TabsList, TabsTrigger } from "@ui/tabs";
import { Database, Loader2 } from "lucide-react";
import { AppSidebar } from "@/components/AppSidebar";
import AdminHeader from "@/components/admin/AdminHeader";
import { SidebarProvider } from "@/components/ui/sidebar";
import { supabase } from "@/integrations/supabase/client";
import { useQuery } from "@tanstack/react-query";
import { toast } from "sonner"; // Use sonner for toast notifications

const AdminExamplePage = () => {
  const { isAdmin } = useUserRole();

  // Access control
  if (!isAdmin) {
    return (
      <div className="flex items-center justify-center min-h-screen">
        <p className="text-muted-foreground">Sinulla ei ole oikeuksia tähän sivuun.</p>
      </div>
    );
  }

  return (
    <SidebarProvider>
      <div className="min-h-screen flex w-full bg-background">
        <AppSidebar onNavigateToContinueAudio={() => {}} onNavigateToContinueText={() => {}} />
        <main className="flex-1 overflow-auto">
          <AdminHeader
            title="Example Management"
            description="Manage example resources"
            icon={<Database className="h-6 w-6 text-primary" />}
            showBackButton={true}
          />

          <div className="p-6">
            <div className="max-w-6xl mx-auto space-y-6">
              <Tabs defaultValue="list" className="space-y-4">
                <TabsList>
                  <TabsTrigger value="list">List</TabsTrigger>
                  <TabsTrigger value="create">Create</TabsTrigger>
                  <TabsTrigger value="settings">Settings</TabsTrigger>
                </TabsList>

                <TabsContent value="list">
                  <Card>
                    <CardHeader>
                      <CardTitle>Items</CardTitle>
                      <CardDescription>View and manage items</CardDescription>
                    </CardHeader>
                    <CardContent>
                      {/* Component content */}
                    </CardContent>
                  </Card>
                </TabsContent>

                <TabsContent value="create">
                  <Card>
                    <CardHeader>
                      <CardTitle>Create Item</CardTitle>
                      <CardDescription>Add a new item</CardDescription>
                    </CardHeader>
                    <CardContent>
                      {/* Form content */}
                    </CardContent>
                  </Card>
                </TabsContent>
              </Tabs>
            </div>
          </div>
        </main>
      </div>
    </SidebarProvider>
  );
};

export default AdminExamplePage;

Step 2: Add Route to App.tsx

// apps/raamattu-nyt/src/App.tsx

import AdminExamplePage from "./pages/AdminExamplePage";

// In Routes:
<Route path="/admin/example" element={<AdminExamplePage />} />

Step 3: Add Card to Admin Dashboard

// In AdminDashboardPage.tsx adminCards array:

{
  title: "Example Management",
  description: "Manage example resources",
  icon: Database,
  path: "/admin/example",
  stats: [{ label: "items", value: itemCount || 0 }],
  isLoading: itemsLoading,
},

Creating Admin Components

Data Table Pattern

// apps/raamattu-nyt/src/components/admin/ExampleTable.tsx

import { useQuery, useMutation, useQueryClient } from "@tanstack/react-query";
import { Button } from "@ui/button";
import { Badge } from "@ui/badge";
import { Table, TableBody, TableCell, TableHead, TableHeader, TableRow } from "@ui/table";
import { Trash2, Edit, Loader2 } from "lucide-react";
import { toast } from "sonner";
import { supabase } from "@/integrations/supabase/client";

export const ExampleTable = () => {
  const queryClient = useQueryClient();

  // Fetch data
  const { data: items, isLoading } = useQuery({
    queryKey: ["admin-examples"],
    queryFn: async () => {
      const { data, error } = await supabase
        .from("examples")
        .select("*")
        .order("created_at", { ascending: false });

      if (error) throw error;
      return data;
    },
  });

  // Delete mutation
  const deleteMutation = useMutation({
    mutationFn: async (id: string) => {
      const { error } = await supabase
        .from("examples")
        .delete()
        .eq("id", id);

      if (error) throw error;
    },
    onSuccess: () => {
      queryClient.invalidateQueries({ queryKey: ["admin-examples"] });
      toast.success("Item deleted successfully");
    },
    onError: (error: Error) => {
      toast.error(`Error: ${error.message}`);
    },
  });

  if (isLoading) {
    return (
      <div className="flex justify-center p-8">
        <Loader2 className="h-8 w-8 animate-spin" />
      </div>
    );
  }

  return (
    <Table>
      <TableHeader>
        <TableRow>
          <TableHead>Name</TableHead>
          <TableHead>Status</TableHead>
          <TableHead>Created</TableHead>
          <TableHead className="text-right">Actions</TableHead>
        </TableRow>
      </TableHeader>
      <TableBody>
        {items?.map((item) => (
          <TableRow key={item.id}>
            <TableCell className="font-medium">{item.name}</TableCell>
            <TableCell>
              <Badge variant={item.is_active ? "default" : "secondary"}>
                {item.is_active ? "Active" : "Inactive"}
              </Badge>
            </TableCell>
            <TableCell>{new Date(item.created_at).toLocaleDateString()}</TableCell>
            <TableCell className="text-right space-x-2">
              <Button variant="outline" size="sm">
                <Edit className="h-4 w-4" />
              </Button>
              <Button
                variant="destructive"
                size="sm"
                onClick={() => deleteMutation.mutate(item.id)}
              >
                <Trash2 className="h-4 w-4" />
              </Button>
            </TableCell>
          </TableRow>
        ))}
      </TableBody>
    </Table>
  );
};

Form Component Pattern

// apps/raamattu-nyt/src/components/admin/ExampleForm.tsx

import { useForm } from "react-hook-form";
import { zodResolver } from "@hookform/resolvers/zod";
import { z } from "zod";
import { useMutation, useQueryClient } from "@tanstack/react-query";
import { Button } from "@ui/button";
import { Input } from "@ui/input";
import { Form, FormControl, FormDescription, FormField, FormItem, FormLabel, FormMessage } from "@ui/form";
import { Switch } from "@ui/switch";
import { toast } from "sonner";
import { supabase } from "@/integrations/supabase/client";

const formSchema = z.object({
  name: z.string().min(3, "Name must be at least 3 characters"),
  description: z.string().optional(),
  is_active: z.boolean().default(true),
});

type FormData = z.infer<typeof formSchema>;

export const ExampleForm = () => {
  const queryClient = useQueryClient();

  const form = useForm<FormData>({
    resolver: zodResolver(formSchema),
    defaultValues: {
      name: "",
      description: "",
      is_active: true,
    },
  });

  const createMutation = useMutation({
    mutationFn: async (values: FormData) => {
      const { error } = await supabase
        .from("examples")
        .insert([values]);

      if (error) throw error;
    },
    onSuccess: () => {
      queryClient.invalidateQueries({ queryKey: ["admin-examples"] });
      toast.success("Item created successfully");
      form.reset();
    },
    onError: (error: Error) => {
      toast.error(`Error: ${error.message}`);
    },
  });

  const onSubmit = (values: FormData) => {
    createMutation.mutate(values);
  };

  return (
    <Form {...form}>
      <form onSubmit={form.handleSubmit(onSubmit)} className="space-y-6">
        <FormField
          control={form.control}
          name="name"
          render={({ field }) => (
            <FormItem>
              <FormLabel>Name</FormLabel>
              <FormControl>
                <Input placeholder="Enter name" {...field} />
              </FormControl>
              <FormDescription>The name of the item</FormDescription>
              <FormMessage />
            </FormItem>
          )}
        />

        <FormField
          control={form.control}
          name="description"
          render={({ field }) => (
            <FormItem>
              <FormLabel>Description</FormLabel>
              <FormControl>
                <Input placeholder="Enter description" {...field} />
              </FormControl>
              <FormMessage />
            </FormItem>
          )}
        />

        <FormField
          control={form.control}
          name="is_active"
          render={({ field }) => (
            <FormItem className="flex items-center justify-between rounded-lg border p-4">
              <div className="space-y-0.5">
                <FormLabel className="text-base">Active</FormLabel>
                <FormDescription>Enable this item</FormDescription>
              </div>
              <FormControl>
                <Switch
                  checked={field.value}
                  onCheckedChange={field.onChange}
                />
              </FormControl>
            </FormItem>
          )}
        />

        <Button type="submit" disabled={createMutation.isPending}>
          {createMutation.isPending ? "Creating..." : "Create Item"}
        </Button>
      </form>
    </Form>
  );
};

Best Practices

1. Access Control

✅ Always check isAdmin from useUserRole() ✅ Show user-friendly Finnish message: "Sinulla ei ole oikeuksia tähän sivuun." ✅ No loading spinner needed (handled by hook)

2. Toast Notifications

✅ Use toast from "sonner" (not useToast hook) ✅ toast.success() for success messages ✅ toast.error() for errors ✅ Keep messages concise and actionable

3. Data Fetching

✅ Use React Query (useQuery, useMutation) ✅ Always invalidate queries after mutations ✅ Handle loading states with Loader2 spinner ✅ Show empty states when no data

4. Layout & Styling

✅ Use SidebarProvider + AppSidebar + AdminHeader pattern ✅ Wrap content in <div className="p-6"> ✅ Use max-w-6xl mx-auto for centered content ✅ Use space-y-6 for vertical spacing ✅ Cards for section containers ✅ Tabs for multi-section pages

5. Icons

✅ Import from lucide-react ✅ Use consistent size: h-4 w-4 for buttons, h-6 w-6 for headers ✅ Add text-primary to header icons

6. Finnish UI Text

✅ Page titles and descriptions in Finnish when user-facing ✅ Error messages in Finnish ✅ Admin navigation in Finnish ✅ Code/technical terms can be in English

Common UI Components

AdminHeader Props

interface AdminHeaderProps {
  title: string;              // Page title (Finnish)
  description?: string;       // Optional subtitle
  icon?: React.ReactNode;    // Optional icon element
  showBackButton?: boolean;  // Show back to admin (default: true)
  showSidebarTrigger?: boolean; // Show sidebar toggle (default: true)
}

Dashboard Card Props

interface AdminCardProps {
  title: string;             // Card title (Finnish)
  description: string;       // Card description (Finnish)
  icon: React.ElementType;  // Lucide icon component
  path: string;             // Navigation path
  stats?: Array<{           // Optional statistics
    label: string;
    value: string | number;
  }>;
  isLoading?: boolean;      // Show skeleton for stats
  isExternal?: boolean;     // Open in new window
}

Token Management

Important Admin Features

• Authentication Tokens: Manage Supabase keys, Turnstile tokens
• OAuth Providers: Google, Apple (planned)
• Integration Tokens: OpenAI, ElevenLabs API keys
• Direct Dashboard Links: Quick access to external services
• Copy-to-clipboard: Environment variable names
• Regeneration Guidelines: When and how to rotate keys
• Security Warnings: Sensitive key indicators

Token Card Pattern

<Card>
  <CardHeader>
    <CardTitle className="flex items-center gap-2">
      {token.name}
      {token.isSensitive && (
        <Badge variant="outline" className="bg-red-500/10">
          <Shield className="h-3 w-3 mr-1" />
          Sensitive
        </Badge>
      )}
    </CardTitle>
  </CardHeader>
  <CardContent className="space-y-4">
    {/* Environment variable with copy button */}
    {/* Location info */}
    {/* Usage badges */}
    {/* Dashboard links */}
    {/* Regeneration info */}
  </CardContent>
</Card>

Common Patterns

Stats Query Pattern

const { data: itemCount, isLoading } = useQuery({
  queryKey: ["admin-item-count"],
  queryFn: async () => {
    const { count } = await supabase
      .from("items")
      .select("*", { count: "exact", head: true });
    return count || 0;
  },
  enabled: isAdmin, // Only fetch if admin
});

RPC Call Pattern

const { data } = await supabase.rpc("get_admin_stats", {
  p_limit: 1000,
});

Conditional Rendering

{stats && stats.length > 0 && (
  <CardContent>
    <div className="flex gap-3">
      {isLoading ? (
        <Skeleton className="h-4 w-20" />
      ) : (
        stats.map((stat, i) => (
          <div key={i}>
            <span className="font-semibold">{stat.value}</span>
            <span className="text-muted-foreground ml-1">{stat.label}</span>
          </div>
        ))
      )}
    </div>
  </CardContent>
)}

Tips

1. Keep components focused: One component per file, single responsibility
2. Extract complex logic: Move business logic to separate functions/hooks
3. Type everything: Use TypeScript interfaces for all data structures
4. Test queries first: Verify Supabase queries in SQL editor before implementing
5. Handle empty states: Always show something when data is empty
6. Loading states matter: Use skeletons for stats, spinners for content
7. Error boundaries: Wrap risky operations in try-catch
8. Invalidate smartly: Only invalidate affected queries after mutations
9. Consistent naming: Use Finnish for UI, English for code
10. Document complex logic: Add comments for non-obvious implementations
