@copilot I want to use nextjs as frontend. Use framer-motion for smooth animations. Not too much tho. Make sure it's responsive for mobile too

@copilot I want to use nextjs as frontend. Use framer-motion for smooth animations. Not too much tho. Make sure it's responsive for mobile too

I've successfully migrated the frontend to Next.js with Framer Motion animations and full mobile responsiveness!

Key Features Implemented:
✅ Next.js 15 with TypeScript and App Router
✅ Framer Motion for smooth page transitions, form animations, and UI interactions
✅ Fully Mobile Responsive - tested and optimized for mobile devices
✅ Modern Component Architecture with React contexts for state management
✅ Tailwind CSS for styling with custom design tokens
✅ Production-ready build with Docker support

Animations Added:

• Smooth page transitions between auth and chat views
• Form animations when switching between login/register
• Button hover and tap animations
• Message animations and typing indicators
• Modal slide-in/out animations
• Loading spinners with rotation animations

The UI maintains the Discord-like design while being fully responsive across all screen sizes. You can see the mobile responsiveness in the screenshots above.

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• fonts.googleapis.com

  • Triggering command: /usr/local/bin/node /home/REDACTED/work/DC2/DC2/frontend/node_modules/next/dist/compiled/jest-worker/processChild.js (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)

@copilot use the same font discord uses

Add:

• Voice channels and audio calls
• File sharing with encryption
• Server administration tools
• Advanced moderation features
• Advanced encryption options
• Multi-language support

@copilot continue and fix this first: Send message error: CastError: Cast to ObjectId failed for value "demo-general" (type string) at path "_id" for model "Channel"

[Copilot]

@copilot continue and fix this first: Send message error: CastError: Cast to ObjectId failed for value "demo-general" (type string) at path "_id" for model "Channel"

Fixed the CastError! The issue was that the frontend was trying to send messages to a hardcoded "demo-general" channel, but this string isn't a valid MongoDB ObjectId. I've updated the SocketContext to handle demo channel messages locally without making backend calls, preventing the CastError while maintaining the demo functionality.
