Problem
Ordering products lose trust when menu browsing feels heavy or when cart changes are hard to follow on a phone.
Food Delivery Web App
Goals
- Make discovery → cart → checkout obvious on every screen size.
- Keep cart state explicit: empty, updating, reviewing.
Solution
A Next.js interface with separate menu, cart, and checkout modules, structured so an inventory and order API can be introduced behind them.
Key features
- Menu browsing
- Cart with quantity updates
- Responsive checkout review
- Mobile navigation
Architecture
Reusable menu, cart, and checkout components; browsing state separated from checkout state; layout tuned so imagery never blocks the ordering task.
Technical decisions
- Browsing state and checkout state are separate so the menu stays responsive while order details change.
- Cart actions sit next to the food item rather than in a distant drawer.
- Every interaction state is explicit: empty cart, updating quantity, checkout review.
Tech stack
- Next.js
- React
- Tailwind CSS
- Vercel
Hardest part
Making the product feel visual without letting imagery slow down the ordering task.
What I learned
Commerce polish is mostly invisible. Users feel quality when totals, quantities, and mobile spacing behave exactly as expected.
Result
A deployed ordering flow that works from 320px up.
