feat(showroom): add public showroom route with username and isPublic …

[Yuva-Deekshitha-N]

…schema fields

Description

Adds the backend groundwork for the Public Showroom feature, allowing resellers to share a public-facing page of their listed inventory at /.

Schema changes:

-> Added username String? @unique to the User model — enables vanity URL routing
-> Added isPublic Boolean @default(false) to InventoryItem — per-item opt-in visibility control

New route (/:username):

-> Resolves the username to a user, returns 404 if not found
-> Fetches only items where isPublic: true using Prisma select — sensitive fields (purchasePrice, purchaseDate, userId, notes) are never sent to the client
-> Converts askingPrice Decimal to Number before serialization to prevent hydration issues
-> Renders a responsive card grid with item name, brand, size, and asking price

📝 Summary

The provided pull request introduces a new route for user profiles, allowing users to view their public inventory items. The changes include updates to the Prisma schema, adding a username field to the User model and an isPublic field to the InventoryItem model. A new route, /:username, is added to handle requests for user profiles.

📂 Files Changed

• app/routes.ts: Added a new route for user profiles.
• app/routes/$username.tsx: Created a new file for the user profile route, including a loader function and a React component.
• prisma/migrations/20260701_add_username_and_ispublic/migration.sql: Added a new migration to update the database schema.
• prisma/schema.prisma: Updated the Prisma schema to include the new fields.
• package-lock.json: Updated the package lock file.

🎭 Code Poem

Users can now view their items with ease,
Public profiles are available, if you please.
The Prisma schema's been updated with care,
And the new route's ready, with data to share.

🚨 Bugs & Architectural Violations

* The `PublicShowroom` component is not placed in the `app/blocks/` directory, which is the required location for UI components. It should be moved to `app/blocks/__global/PublicShowroom`. * The component uses inline styles, which is not recommended. Instead, it should use Vanilla CSS Modules (`.module.css`) for styling. * The `loader` function does not handle errors properly. It should be updated to handle potential errors when fetching data from the database. * The `PublicShowroom` component does not include any accessibility features, such as `aria-hidden` or `role` attributes. These should be added to ensure the component is accessible. * The component uses `var(--color-border)` and `var(--color-text-muted)`, which are not defined in the provided code. These variables should be defined in a CSS file or replaced with actual color values.

💡 Suggestions & Best Practices

* Consider adding a `defer` function to the `loader` function to improve performance. * Use `transform` or `opacity` for CSS animations instead of triggering main-thread repaints. * Add a `key` prop to the `img` element to ensure it is properly updated when the image URL changes. * Consider adding a loading indicator or a skeleton component to display while the data is being fetched. * Use a more robust error handling mechanism, such as a try-catch block, to handle potential errors when fetching data from the database. * Consider adding a `meta` tag to the `head` of the HTML document to provide metadata about the user profile page.

Hi! I hope you're doing well.

I just wanted to follow up on my pull request. I noticed it has been open for a few days, so I was wondering if you've had a chance to review it.

If there are any issues or changes needed from my side, please let me know. I'd be happy to make the necessary updates.

Thank you for your time!

Hey @Yuva-Deekshitha-N! Thanks for your patience here. I just took a deep dive into the code, and overall, you’ve done a really solid job laying the groundwork for this.

I especially love how you handled the data security. Using select in the Prisma query to strictly whitelist fields is exactly the right move to ensure sensitive info like purchasePrice never accidentally leaks to the client. Great stuff there!

Before we merge, there are a few architectural things and edge cases we need to tighten up:

1. The "Sold Out" Edge Case
Right now, the Prisma query fetches all public items, but it doesn't check their status. That means if an item is SOLD, it will still show up on the showroom looking exactly like an available item with a price tag! That’s going to lead to some very frustrated buyers. Could you either filter out sold items in the query (status: { in: ['IN_STOCK', 'LISTED'] }), or add a visual "SOLD" badge to the UI card if it's no longer available?

2. Route Collisions
The original issue asked for a root-level /$username route, but looking at it now, that's actually pretty dangerous for us at scale. If a user sets their username to "login" or "settings", their public profile will become permanently unreachable because our static app routes will intercept the traffic. To future-proof this, let's scope it! Could you rename the route file to u.$username.tsx (which will mount it safely at /u/username)?

3. Frontend Architecture
We have a strict rule in the codebase against inline styles. Could you extract that card grid UI out of the route file and into a new component in app/blocks/showroom/, and use a standard .module.css file for the styling?

4. Error Boundaries
Your loader correctly throws a 404 Response if a user isn't found, but the route file doesn't export an ErrorBoundary. Because of this, a 404 will bubble all the way up and trigger our root error boundary, which is a bit jarring. Could you export a simple ErrorBoundary from the route to handle that gracefully?

Lastly, it looks like package-lock.json accidentally caught a local environment change (the fsevents flag). Just revert that file so we keep the PR clean.

You are doing awesome work here. Let me know if you run into any issues implementing these tweaks and I'll be happy to help!

Review

Strengths

• The contributor has followed the existing architecture and coding standards.
• The changes are well-structured and easy to understand.
• The addition of a new CSS module for the user profile component is a good practice for maintaining styling consistency.

Critical Issues - Must Fix Before Merge

Blocking issues: security vulnerabilities, architectural violations, race conditions, breaking changes.

• [SECURITY] The Prisma queries in the updated UserProfile.ts file are missing userId filters, which could lead to unauthorized data access. Suggested fix: Add where: { id: userId } to the Prisma queries.
• [ARCHITECTURE] The use of process.env in the client-side code is not compliant with the environment variable rules. Suggested fix: Replace process.env with import.meta.env.VITE_* in the client-side code.

Warnings - Should Fix

Non-blocking issues ideally addressed before merge.

• [PERFORMANCE] The updated UserProfile.ts file could benefit from additional error handling to improve robustness. Suggestion: Add try-catch blocks to handle potential errors during data retrieval.
• [ACCESSIBILITY] The new UserProfile.css module could include more accessibility attributes to enhance the user experience. Suggestion: Add aria-label and role attributes to the relevant HTML elements.

Suggestions - Nice to Have

Optional improvements.

Hey @Yuva-Deekshitha-N, fantastic work on this!

I just went through the updated code line by line and you nailed every single point:

1. The visual "SOLD" badge on the cards is a great UX decision and was implemented perfectly.
2. Scoping the route to /u/:username completely eliminates our collision risks.
3. The extraction into showroom-grid.tsx with the CSS Module looks beautiful and strictly adheres to our frontend architecture rules.
4. The ErrorBoundary handles the 404 gracefully.
5. Thanks for cleaning up the package-lock.json as well!

This is exactly the kind of high-quality contribution we look for. The PR is fully approved on my end. I'll go ahead and merge this in. Great job!
