Prerequisites:

Approach to build Community Marketplace App:

Create a new ReactJS project using a tool like Create React App. Install necessary libraries such as React Router for routing, Bootstrap for styling, and any other libraries needed for state management or API calls.
Create components for the navbar, product listings, product details, adding new products form, and other necessary components. Organize the components in a structured manner for better maintainability and reusability.
Allow users to list items they want to sell by creating a form component for adding new products. Include fields for images, descriptions, prices, contact details, etc., in the form for users to fill out when listing their products.
Implement search functionality to allow users to search for specific products based on keywords. Implement filter functionality to display products from a specific category or based on other criteria chosen by the user.
Utilize the useState hook to manage the states of various components in the application, such as form data and search/filter criteria. Use React Router to set up routing for different pages of the application, such as the product listings page, product details page, and add product page.
Utilize useParams hook from React Router to get the Product ID and display details about a specific product on the product details page.

Steps to build Community Marketplace App:

Step 1: Create a reactJS application by using this command

npx create-react-app marketplace

Step 2: Navigate to project directory

cd marketplace

Step 3: Install the necessary packages/libraries in your project using the following commands.

npm install bootstrap
npm install react-router-dom
npm install react-icons --save
npm install react-toastify
