Live in-chat message UI

[AnikMajumdar]

This is the implementation of the UI for the in-chat messages. This is the right side of the messaging screen, not including the list of messages on the left.

Quick Start

URL to test this feature: http://localhost:3001/chat/507f1f77bcf86cd799439011

Start backend server:

cd server
npm run dev

Start Next.js client:

cd client
npm run dev

How It Works

The messages displayed at the URL above are whatever messages exist in MongoDB with conversationId: 507f1f77bcf86cd799439011. Any message stored with that conversation ID — regardless of who sent it — will be fetched and displayed. The senderId field on each message determines whether it renders as a "sent" bubble (right side) or "received" bubble (left side), based on comparing it against the currentUserId from localStorage.

Testing the Product Image

To test the product image display and styling, open your browser's DevTools console and set the following localStorage values before navigating to the chat URL:

localStorage.setItem('chatProductName', 'Test Product Name');
localStorage.setItem(
'chatProductImage',

localStorage.setItem('userId', 'user123');
localStorage.setItem('receiverIds', '["user456"]');
localStorage.setItem(
'chatOtherUserAvatar',
'https://via.placeholder.com/56x56?text=Avatar',
);

Then navigate to: http://localhost:3001/chat/507f1f77bcf86cd799439011

Expected behavior:

• Product image displays below the header with dimensions 264×224px
• Image has 20px border-radius and centered positioning
• Placeholder background color (#d9d9d9) shows while image loads
• Image maintains aspect ratio with object-fit: cover

Files

• page.tsx — Connects to Socket.IO, fetches message history via REST, manages state
• ChatWindow.tsx — Layout with back button, product name header, product image, messages area, and input bar
• MessageBubble.tsx — Renders individual messages with avatar (received) or "Delivered" label (sent)
• MessageInput.tsx — Input bar with link/camera icons and send arrow

Next Steps

Authentication & State Management

Current State: Manual reads of userId and token from localStorage.
What's Needed: Implement formal login/register pages and an Auth Context/Provider. This should store the JWT and user data centrally upon login.

User Identity Tracking

Current State: currentUserId is pulled directly via localStorage.getItem("userId").
What's Needed: User identity should be derived automatically from the Auth Context after a successful login.

Receiver Identification

Current State: Pulls receiver data via localStorage.getItem("receiverIds").
What's Needed: Receiver IDs should be derived dynamically from the active conversation data (identifying the other participant(s)).

Product Information Mapping

Current State: Pulls chatProductName etc. from localStorage.
What's Needed: Logic should fetch the conversation → identify the linked listing → display product name and image directly from that listing's data.

Other User's Profile/Avatar

Current State: Hardcoded from localStorage.
What's Needed: Dynamically fetch the other participant's profile information from the /users/:id endpoint.

Conversations List Management

Current State: Feature does not exist.
What's Needed: Create a central Chat page (e.g., /chat) that calls GET /conversations/:userId. This should list all active conversations with a preview of the last message sent.

Starting New Conversations

Current State: Requires manual URL navigation.
What's Needed: Implement a "Message Seller" button on product listings. This button should call POST /conversations and then navigate the user to /chat/{newConversationId}.

Overall, this looks great! It works very well, matches the Figma for the most part, and I didn't run into any bugs while testing. I'm definitely impressed! I just left some specific comments and have a few overall things to comment/ask about:

1. Just a file refactoring comment-- could we move all of the components for this page (ChatWindow.tsx, MessageBubble.tsx, MessageInput.tsx) into a page-level components folder? I believe the route would be client/src/app/(pages)/chat/[conversationId]/_components. This will just keep things more organized. Each component should also be within its own folder. Example: ChatWindow would be in client/src/app/(pages)/chat/[conversationId]/_components/ChatWindow/ChatWindow.tsx
2. The second part of my file refactoring comment, and the reason we need separate folders for each component: Let's define separate stylesheets for each component. For example, ChatWindow would get its own SCSS file ChatWindow.module.scss, within the same folder as ChatWindow.tsx.
3. Make sure to format all files with Prettier. I noticed when I ran the formatter, there were things changed for each file, so make sure to run the formatter for each of the files included in your PR. You can also run npm run format to format all files at once.
4. I notice there's a product image you have in the component, and it is styled as well. Could you include instructions in the PR description for how to test the PR with a conversation that has a product image so I can check on the product image implementation? General screenshots in the PR description would also be appreciated in PR descriptions going forward!

Don't forget to resolve comments once you're done addressing them, and feel free to request another review from me whenever you're done making changes. Keep up the good work!

Changes Made

1. TypeScript & Type Management

• Converted Message interface to a type for better flexibility
• Created centralized types file at messaging.d.ts
• Removed duplicate Message type declarations across components

2. Component Structure Refactoring

Reorganized chat components into a dedicated _components structure:

• _components/ChatWindow/ — Chat window container component
• _components/MessageBubble/ — Individual message bubble component
• _components/MessageInput/ — Message input area component

Each component now has its own isolated folder and styling module.

3. Styling Improvements

Split the original page.module.scss into component-specific SCSS modules:

• ChatWindow/ChatWindow.module.scss
• MessageBubble/MessageBubble.module.scss
• MessageInput/MessageInput.module.scss

Additional styling updates:

• Enforced 8px grid spacing system
• Updated padding values (20px → 24px)
• Adjusted gaps (5px → 4px, 10px → 12px)
• Refined avatar dimensions (53px → 56px)
• Moved inline styles into SCSS modules for maintainability

4. Next.js Image Optimization

Replaced HTML <img> tags with Next.js Image components:

• Added automatic image optimization for avatars, product images, and attachments
• Added proper fill layouts with position: relative containers

Extracted inline SVGs into dedicated assets:

• public/messaging/link.svg
• public/messaging/camera.svg
• public/messaging/send.svg

5. Code Style & Best Practices

Hey @AnikMajumdar , just dropping by with my second review. I noticed some of the comments I left last time were not fully resolved-- in the future, please be more careful to fully address all comments before re-requesting a review! The good news is that most of these are small fixes, though. Just make sure to pull from main and resolve merge conflicts, and resolve the new inline comments.

Just two more general things.

1. Please update the original PR description instead of adding a discussion comment.

2. I notice there's a product image you have in the component, and it is styled as well. Could you include instructions in the PR description for how to test the PR with a conversation that has a product image so I can check on the product image implementation?
   #51 (review)

There are still a few places where comments I previously left were not fully resolved (i.e. different instances of the same problem).

Also, could you please remove your changes to files that are unrelated to this PR? I'm assuming the changes got applied because you tried to run the formatter on all files, creating changes on a bunch of other files. Could we remove those changes just to make sure we don't cause merge conflicts with other peoples' work? Sorry for the inconvenience!

So you haven't given this container any height, so it's defaulting to a height of 0 and the image isn't showing up on my screen. It looks like this:

When I manually add a height to the div such as height: 200px it does display.

I don't think this matches the Figma or the screenshot you attached to your PR-- did you forget to push a fix for this?
