I'll implement the login and signup functionality for your EduNexus platform, ensuring users must be authenticated to access features.

I've implemented a complete authentication system for your EduNexus platform with the following features:

1. Login and Signup Links: Added to the top right corner of the header
2. Login Page: Created based on the provided image with username/password fields
3. Signup Page: Created based on the provided image with all required fields
4. Authentication Context: Implemented to manage user authentication state
5. Protected Features: All interactive elements require authentication
6. Auth Required Modal: Shows when unauthenticated users try to access protected features

How It Works:

1. Authentication Flow:

   • Users can click on Login/Signup in the header
   • After successful login/signup, they're redirected to the home page
   • Authentication state is stored in localStorage for persistence

2. Protected Features:

   • All action buttons, community links, discussions, events, and resources
   • When clicked by unauthenticated users, they trigger an "Auth Required" modal
   • The modal offers options to login or signup

3. Responsive Design:

   • Works on mobile and desktop devices
   • Mobile menu includes login/signup options

How to Test:

1. Click on "Login" or "Sign Up" in the header
2. Enter credentials (any values will work for this demo)
3. After logging in, you'll be able to access all features
4. Try clicking on buttons before logging in to see the auth required modal

The implementation uses Next.js with the App Router, React Context for state management, and Tailwind CSS for styling, matching the design of your original application.

How to Add This Code to VS Code

Here's a step-by-step guide to set up this project in VS Code:

1. Create a New Next.js Project

First, you'll need to create a new Next.js project:

When prompted, select the following options:

• Would you like to use TypeScript? → Yes
• Would you like to use ESLint? → Yes
• Would you like to use Tailwind CSS? → Yes
• Would you like to use src/ directory? → No
• Would you like to use App Router? → Yes
• Would you like to customize the default import alias? → No (or Yes and use @/*)

2. Install Required Dependencies

Navigate to your project directory and install the required dependencies:

3. Install shadcn/ui Components

Set up shadcn/ui components:

When prompted, select these options:

• Would you like to use TypeScript? → Yes
• Which style would you like to use? → Default
• Which color would you like to use as base color? → Slate
• Where is your global CSS file? → app/globals.css
• Do you want to use CSS variables? → Yes
• Are you using a custom tailwind prefix? → No
• Where is your tailwind.config.js located? → tailwind.config.ts
• Configure the import alias for components? → @/components
• Configure the import alias for utils? → @/lib/utils
• Are you using React Server Components? → Yes

Then install the required components:

4. Create the File Structure

Create the necessary folders and files:

5. Add the Code Files

Now, copy and paste the code I provided into the corresponding files:

1. app/layout.tsx - Replace the existing file
2. app/page.tsx - Replace the existing file
3. app/globals.css - Replace the existing file
4. tailwind.config.ts - Replace the existing file
5. app/login/page.tsx - Create this file
6. app/signup/page.tsx - Create this file
7. context/auth-context.tsx - Create this file
8. components/header.tsx - Create this file
9. components/footer.tsx - Create this file
10. components/home-page.tsx - Create this file
11. components/events-page.tsx - Create this file
12. components/communities-page.tsx - Create this file
13. components/discussions-page.tsx - Create this file
14. components/resources-page.tsx - Create this file
15. components/chatbot.tsx - Create this file
16. components/auth-required-modal.tsx - Create this file

6. Fix Missing Imports

In some components, you might need to add the missing import for useState:

Add this import to any component that uses useState but doesn't have the import.

7. Run the Development Server

Start the development server:

Your application should now be running at http://localhost:3000.

Alternative: Use the "Add to Codebase" Feature

If you're viewing this in v0, you can use the "Add to Codebase" feature:

1. Click the "..." menu at the top right of the code block
2. Select "Add to codebase"
3. Choose to create a new project or add to an existing one
4. Follow the prompts to complete the installation

This will automatically set up the project with all the necessary files and dependencies.

Troubleshooting

If you encounter any issues:

1. Missing dependencies: Run npm install to ensure all dependencies are installed
2. TypeScript errors: Make sure you have the correct TypeScript version (npm install typescript@latest)
3. Component errors: Ensure you've installed all the required shadcn/ui components
