Zod: A TypeScript-first schema declaration and validation library, used for form validation and ensuring data integrity.

3. Interesting Implementation Details

State Management with Redux

The application uses Redux Toolkit for state management, which simplifies the process of managing global state. The following code snippet demonstrates how to set up a slice for managing the cart state:

import { createSlice } from '@reduxjs/toolkit';

const cartSlice = createSlice({
  name: 'cart',
  initialState: {
    items: [],
    totalAmount: 0,
  },
  reducers: {
    addItem(state, action) {
      const newItem = action.payload;
      state.items.push(newItem);
      state.totalAmount += newItem.price;
    },
    removeItem(state, action) {
      const id = action.payload;
      const existingItem = state.items.find(item => item.id === id);
      if (existingItem) {
        state.items = state.items.filter(item => item.id !== id);
        state.totalAmount -= existingItem.price;
      }
    },
  },
});

export const { addItem, removeItem } = cartSlice.actions;
export default cartSlice.reducer;

Responsive Design with Tailwind CSS

The application employs Tailwind CSS for styling, allowing for rapid development of responsive layouts. For example, the following code snippet demonstrates how to create a responsive card component for displaying products:

<div class="max-w-sm rounded overflow-hidden shadow-lg m-4">
  <img class="w-full" src="product-image.jpg" alt="Product Image">
  <div class="px-6 py-4">
    <div class="font-bold text-xl mb-2">Product Name</div>
    <p class="text-gray-700 text-base">Product description goes here.</p>
  </div>
  <div class="px-6 pt-4 pb-2">
    <span class="inline-block bg-gray-200 rounded-full px-3 py-1 text-sm font-semibold text-gray-700 mr-2 mb-2">Category</span>
    <span class="inline-block bg-gray-200 rounded-full px-3 py-1 text-sm font-semibold text-gray-700">Price: $XX.XX</span>
  </div>
</div>

4. Technical Challenges Overcome

Handling Cart Functionality

One of the significant challenges was implementing the cart functionality, particularly the restriction of adding products from multiple vendors. The solution involved maintaining a single vendor context in the cart state. If a user attempts to add a product from a different vendor, a warning is displayed:

if (currentVendor !== newProduct.vendor) {
  alert('You can only add products from one vendor at a time.');
}

Authentication and Authorization

Implementing secure authentication using JWT posed challenges, particularly in managing token expiration and refresh. The application uses a middleware to check the validity of the JWT on protected routes
