Building a Secure Employee Dashboard with Facial Authentication: A Comprehensive Next.js Tutorial

Are you ready to revolutionize your workplace management? In this comprehensive tutorial, we're diving deep into creating a state-of-the-art employee dashboard that leverages facial authentication. We'll be using some of the hottest tools in web development: Next.js, FACEIO, and Shadcn UI. By the end of this guide, you'll have a sleek, secure dashboard that'll make your employees feel like they're living in the future!

What You'll Need Before We Start

Before we dive in, let's make sure you've got all your ducks in a row:

• Node.js installed on your machine
• npm or yarn (whichever floats your boat)

Got all that? Great! Let's get this show on the road.

Setting Up Your Project: The First Steps

Step 1: Kickstarting Your Next.js Project

First things first, let's create our Next.js project. Open up your terminal and type in these magic words:

npx create-next-app@latest faceio-app
cd faceio-app

You'll be asked a few questions. Here's how to answer them:

• TypeScript? Heck yes!
• ESLint? Absolutely!
• Tailwind CSS? You bet!
• src/ directory? Nah, we're good.
• App Router? Yes, please!
• Customize default import alias? We'll pass on this one.

Step 2: Gathering Your Tools

Now, let's grab all the goodies we need. Run this command to install our dependencies:

npm install @faceio/fiojs @shadcn/ui class-variance-authority clsx tailwind-merge

Step 3: Setting Up Your Secret Sauce

Create a file called .env.local in your project's root. This is where we'll keep our secret FACEIO app ID:

NEXT_PUBLIC_FACEIO_APP_ID=your-super-secret-faceio-app-id

Remember to replace 'your-super-secret-faceio-app-id' with your actual FACEIO application ID. Keep it safe!

Step 4: File Structure

Your project structure should look like this:

faceio-app/
├── app/
│   ├── layout.tsx
│   ├── page.tsx
│   └── components/
│       ├── FaceAuth.tsx
│       └── EmployeeDashboard.tsx
├── public/
├── .env.local
├── next.config.js
├── package.json
├── tsconfig.json
└── tailwind.config.js

Step 5: Sprucing Up Tailwind CSS

Time to give Tailwind a makeover. Update your tailwind.config.js file with this fancy configuration:

/** @type {import('tailwindcss').Config} */
module.exports = {
  darkMode: ["class"],
  content: [
    './app/**/*.{ts,tsx}',
  ],
  theme: {
    container: {
      center: true,
      padding: "2rem",
      screens: {
        "2xl": "1400px",
      },
    },
    extend: {
      colors: {
        border: "hsl(var(--border))",
        input: "hsl(var(--input))",
        ring: "hsl(var(--ring))",
        background: "hsl(var(--background))",
        foreground: "hsl(var(--foreground))",
        primary: {
          DEFAULT: "hsl(var(--primary))",
          foreground: "hsl(var(--primary-foreground))",
        },
        secondary: {
          DEFAULT: "hsl(var(--secondary))",
          foreground: "hsl(var(--secondary-foreground))",
        },
        destructive: {
          DEFAULT: "hsl(var(--destructive))",
          foreground: "hsl(var(--destructive-foreground))",
        },
        muted: {
          DEFAULT: "hsl(var(--muted))",
          foreground: "hsl(var(--muted-foreground))",
        },
        accent: {
          DEFAULT: "hsl(var(--accent))",
          foreground: "hsl(var(--accent-foreground))",
        },
        popover: {
          DEFAULT: "hsl(var(--popover))",
          foreground: "hsl(var(--popover-foreground))",
        },
        card: {
          DEFAULT: "hsl(var(--card))",
          foreground: "hsl(var(--card-foreground))",
        },
      },
      borderRadius: {
        lg: "var(--radius)",
        md: "calc(var(--radius) - 2px)",
        sm: "calc(var(--radius) - 4px)",
      },
      keyframes: {
        "accordion-down": {
          from: { height: 0 },
          to: { height: "var(--radix-accordion-content-height)" },
        },
        "accordion-up": {
          from: { height: "var(--radix-accordion-content-height)" },
          to: { height: 0 },
        },
      },
      animation: {
        "accordion-down": "accordion-down 0.2s ease-out",
        "accordion-up": "accordion-up 0.2s ease-out",
      },
    },
  },
  plugins: [require("tailwindcss-animate")],
}

Building the Heart of Your Dashboard

Step 1: Crafting the FaceAuth Component

Let's create the star of our show - the FaceAuth component. Create a new file app/components/FaceAuth.tsx and paste in this code:

import { useEffect } from 'react';
import faceIO from '@faceio/fiojs';
import { Button, Card, CardHeader, CardTitle, CardContent } from '@shadcn/ui';
import { useToast } from '@shadcn/ui';

interface FaceAuthProps {
  onSuccessfulAuth: (data: any) => void;
}

const FaceAuth: React.FC<FaceAuthProps> = ({ onSuccessfulAuth }) => {
  const { toast } = useToast();

  useEffect(() => {
    const faceio = new faceIO(process.env.NEXT_PUBLIC_FACEIO_APP_ID);

    const enrollNewUser = async () => {
      try {
        const userInfo = await faceio.enroll({
          locale: 'auto',
          payload: {
            email: 'employee@example.com',
            pin: '12345',
          },
        });
        toast({
          title: "Success!",
          description: "You're now enrolled in the facial recognition system!",
        });
        console.log('User Enrolled!', userInfo);
      } catch (errCode) {
        toast({
          title: "Oops!",
          description: "Enrollment failed. Please try again.",
          variant: "destructive",
        });
        console.error('Enrollment Failed', errCode);
      }
    };

    const authenticateUser = async () => {
      try {
        const userData = await faceio.authenticate();
        toast({
          title: "Welcome back!",
          description: "Authentication successful.",
        });
        console.log('User Authenticated!', userData);
        onSuccessfulAuth({
          name: 'John Doe',
          position: 'Software Developer',
          department: 'Engineering',
          photoUrl: 'https://example.com/john-doe.jpg',
        });
      } catch (errCode) {
        toast({
          title: "Authentication failed",
          description: "Please try again or enroll.",
          variant: "destructive",
        });
        console.error('Authentication Failed', errCode);
      }
    };

    const enrollBtn = document.getElementById('enroll-btn');
    const authBtn = document.getElementById('auth-btn');

    if (enrollBtn) enrollBtn.onclick = enrollNewUser;
    if (authBtn) authBtn.onclick = authenticateUser;

    return () => {
      if (enrollBtn) enrollBtn.onclick = null;
      if (authBtn) authBtn.onclick = null;
    };
  }, [toast, onSuccessfulAuth]);

  return (
    <Card className="w-full max-w-md mx-auto">
      <CardHeader>
        <CardTitle>Facial Authentication</CardTitle>
      </CardHeader>
      <CardContent className="space-y-4">
        <Button id="enroll-btn" variant="outline" className="w-full">
          Enroll New Employee
        </Button>
        <Button id="auth-btn" variant="default" className="w-full">
          Authenticate
        </Button>
      </CardContent>
    </Card>
  );
};

export default FaceAuth;

Step 2: Building the EmployeeDashboard Component

Now, let's create the dashboard that our employees will see. Create app/components/EmployeeDashboard.tsx:

import { useState } from 'react';
import { Card, CardHeader, CardTitle, CardContent } from '@shadcn/ui';
import { Button, Avatar, Badge, Table, TableBody, TableCell, TableHead, TableHeader, TableRow } from '@shadcn/ui';
import FaceAuth from './FaceAuth';

interface EmployeeData {
  name: string;
  position: string;
  department: string;
  photoUrl: string;
}

const EmployeeDashboard: React.FC = () => {
  const [isAuthenticated, setIsAuthenticated] = useState(false);
  const [employeeData, setEmployeeData] = useState<EmployeeData | null>(null);

  const handleSuccessfulAuth = (data: EmployeeData) => {
    setIsAuthenticated(true);
    setEmployeeData(data);
  };

  const mockAttendanceData = [
    { date: '2024-07-14', timeIn: '09:00 AM', timeOut: '05:30 PM' },
    { date: '2024-07-13', timeIn: '08:55 AM', timeOut: '05:25 PM' },
    { date: '2024-07-12', timeIn: '09:05 AM', timeOut: '05:35 PM' },
  ];

  return (
    <div className="space-y-6">
      {!isAuthenticated ? (
        <FaceAuth onSuccessfulAuth={handleSuccessfulAuth} />
      ) : (
        <>
          <Card>
            <CardHeader>
              <CardTitle>Employee Profile</CardTitle>
            </CardHeader>
            <CardContent className="flex items-center space-x-4">
              <Avatar className="h-20 w-20" src={employeeData?.photoUrl} alt={employeeData?.name} />
              <div>
                <h2 className="text-2xl font-bold">{employeeData?.name}</h2>
                <p className="text-gray-500">{employeeData?.position}</p>
                <Badge variant="outline">{employeeData?.department}</Badge>
              </div>
            </CardContent>
          </Card>

          <Card>
            <CardHeader>
              <CardTitle>Quick Actions</CardTitle>
            </CardHeader>
            <CardContent className="space-y-4">
              <Button className="w-full">Check-in</Button>
              <Button className="w-full" variant="secondary">Request Leave</Button>
            </CardContent>
          </Card>

          <Card>
            <CardHeader>
              <CardTitle>Attendance Records</CardTitle>
            </CardHeader>
            <CardContent>
              <Table>
                <TableHeader>
                  <TableRow>
                    <TableHead>Date</TableHead>
                    <TableHead>Time In</TableHead>
                    <TableHead>Time Out</TableHead>
                  </TableRow>
                </TableHeader>
                <TableBody>
                  {mockAttendanceData.map((record, index) => (
                    <TableRow key={index}>
                      <TableCell>{record.date}</TableCell>
                      <TableCell>{record.timeIn}</TableCell>
                      <TableCell>{record.timeOut}</TableCell>
                    </TableRow>
                  ))}
                </TableBody>
              </Table>
            </CardContent>
          </Card>
        </>
      )}
    </div>
  );
};

export default EmployeeDashboard;

Step 3: Bringing It All Together

Finally, let's update our main page to show off our hard work. Update app/page.tsx:

import EmployeeDashboard from './components/EmployeeDashboard';

export default function Home() {
  return (
    <main className="flex min-h-screen flex-col items-center justify-center p-4">
      <EmployeeDashboard />
    </main>
  );
}

Now, let's set up the layout that'll wrap our entire app. Add this code: app/layout.tsx

import './globals.css'
import type { Metadata } from 'next'
import { Inter } from 'next/font/google'

const inter = Inter({ subsets: ['latin'] })

export const metadata: Metadata = {
  title: 'Employee Dashboard with Facial Authentication',
  description: 'A cutting-edge employee dashboard featuring facial recognition for secure authentication and efficient workplace management.',
}

export default function RootLayout({
  children,
}: {
  children: React.ReactNode
}) {
  return (
    <html lang="en">
      <body className={inter.className}>
        <header className="bg-primary text-white p-4">
          <h1 className="text-2xl font-bold">Faceio Solutions</h1>
        </header>
        <main className="container mx-auto p-4">
          {children}
        </main>
        <footer className="bg-gray-100 text-center p-4 mt-8">
          <p>&copy; 2024 Faceio . All rights reserved.</p>
        </footer>
      </body>
    </html>
  )
}

This layout is like the frame of a house - it provides structure for your entire app. It includes a header with your company name, a main content area where your dashboard will appear, and a footer. Plus, it sets up some SEO magic with metadata!
