- A header with the app name "hamm.er" and a right arrow
- A search bar with a magnifying glass icon
- Two circular icons on the right (one appears to be for users/groups, the other looks like a calendar)
- A channel list showing "#general" with a hashtag icon
- A "Call Room" option with a speaker/audio icon
- The rest of the screen appears to be empty chat space
This is a Discord-like chat interface with a very clean, minimalist dark design. I'll need to recreate this using Next.js and shadcn/ui components with a black and white theme.
For this project, I'll need to create:
- A layout with the sidebar and main chat area
- Header components
- Search functionality
- Channel list components
- Chat message components
- Real-time chat functionality
I'll use a Code Project to implement this as it requires multiple React components and real-time functionality.

Real-time Chat App with Next.js and shadcn/ui
I'll create a real-time chat application that matches the design in your image, using Next.js and shadcn/ui with a black and white theme.

Features Implemented
- Dark Theme - Black background with white text matching the design in the image
- Chat Layout - Sidebar with channels and main chat area
- Channel List - Text channels with # icon and voice channels with speaker icon
- Search Bar - Search functionality with magnifying glass icon
- Real-time Messaging - Send and receive messages in real-time
- User Avatars - Display user avatars next to messages
- Responsive Design - Works on all screen sizes
How It Works
- The app uses a dark theme with black and dark gray backgrounds to match the design in your image
- The sidebar displays channels with appropriate icons (# for text channels, speaker for voice channels)
- The chat area shows messages with user avatars and timestamps
- The
useMessageshook simulates real-time functionality (in a production app, you would integrate with a real-time service like Socket.io or Pusher)
Next Steps
For a production-ready app, you might want to:
- Add authentication using NextAuth.js
- Implement real-time messaging with Socket.io or Pusher
- Add a database like Supabase or MongoDB to store messages and user data
- Implement user presence indicators
- Add file uploads and media sharing
You can install this project by clicking the "Add to codebase" button in the Block view.
I'll update the chat app to match the new channel view design when a user clicks on the "general" option.
Updates Made
I've updated the chat interface to match the design in the new image:
Header Design:
- Added a back arrow on the left
- Styled the channel name with a hashtag and right arrow
- Added a search button on the right
Welcome Message:
- Added the large hashtag icon in a circle
- Added "Welcome to hamm.er/channel" heading
- Added "This is your brand new, shiny server" subtitle
- Added the "Set up your server" button with loading spinner
Message Display:
- Updated the message format to match the design
- Changed the timestamp format to "Today at X:XX PM"
- Changed the user to "Sreeman" with a blue avatar
Message Input:
- Redesigned the input bar with icons for Plus, Gift, Emoji, and Microphone
- Improved the styling to match the dark theme
Now when a user clicks on the "general" channel, they'll see the exact interface shown in your image, with the welcome message, server setup button, and the "Hi" message from Sreeman.
