Introduction

In this tutorial, you will learn how to build a fullstack e-commerce application using Next.js, MongoDB, Tailwind CSS, and styled components. Designed for beginners, this guide will take you through the essential steps to create a functional e-commerce shop that you can showcase in your portfolio.

Step 1: Set Up the Admin Interface with Tailwind CSS

• Start by creating a new Next.js project for the admin interface.
• Install Tailwind CSS:

  npm install tailwindcss
  

• Configure Tailwind by creating a tailwind.config.js file and including Tailwind in your CSS.

Step 2: Implement Admin Authentication

• Use NextAuth.js for authentication:

  npm install next-auth
  

• Set up authentication providers (e.g., Google, credentials).
• Create an API route for authentication under the pages/api/auth/[...nextauth].js path.

Step 3: Design the Admin Dashboard

• Create basic layout components using Tailwind CSS.
• Focus on a clean and user-friendly design to manage products and categories.

Step 4: Manage Products

• Create API routes for handling product CRUD operations:
  • Create a new product
  • Read existing products
  • Update product details
  • Delete a product
• Integrate a form in the admin panel to submit product data.

Step 5: Manage Categories

• Similar to product management, create API endpoints for categories:
  • Create a category
  • Read categories
  • Update category details
  • Delete a category

Step 6: Implement Security Measures

• Protect sensitive routes with middleware to ensure that only authenticated users can access them.
• Consider using environment variables for sensitive information like database connection strings.

Step 7: Ensure Mobile Responsiveness

• Use Tailwind CSS responsive utilities to ensure the admin interface works well on mobile devices.

Step 8: Build the E-commerce Frontend

• Create a new Next.js project for the frontend.
• Set up components for featured products and latest products using Tailwind CSS.

Step 9: Implement Add to Cart Functionality

• Use React's state management to handle cart operations.
• Create a context API to share cart data across components.

Step 10: Set Up Stripe Checkout

• Install Stripe:

  npm install stripe
  

• Create a checkout session using Stripe's API and redirect users to complete their purchase.

Step 11: Show Orders in Admin

• Create a section in the admin panel to display orders placed through the frontend.
• Fetch orders from your MongoDB database.

Step 12: Implement Stripe Webhook

• Set up a webhook to listen for Stripe events (e.g., successful payments).
• Update your database accordingly when a payment is confirmed.

Step 13: Create All Products Page

• Build a page to display all products fetched from your backend.
• Implement pagination if necessary for better performance.

Step 14: Build a Single Product Page

• Create a dynamic page to display individual product details.
• Include options for users to add items to their cart from this page.

Step 15: Make the Frontend Responsive

• Utilize Tailwind CSS's responsive design features to ensure your e-commerce frontend looks good on all devices.
