Step 2: Setting Up Strapi

1. Install Strapi:

   • Create a new Strapi project: npx create-strapi-app my-strapi-backend --quickstart
   • This will start Strapi and open the admin interface at http://localhost:1337/admin.

2. Create Product Content Type:

   • In the Strapi admin panel, create a new content type called Product.
   • Add the following fields:
     • Name: Text field.

   • Ensure the site is responsive and user-friendly.

2. Build and Test:

   • Run the Gatsby build process to generate the static site.
   • Test the site locally to ensure all functionalities (data fetching, product display, cart, and checkout) work as expected.

Detailed Implementation Plan

1. Gatsby Setup

gatsby-config.js:

• Configure plugins for Strapi and Snipcart.
• Example configuration:

module.exports = {
  siteMetadata: {
    title: 'My E-commerce Site',
  },
  plugins: [
    `gatsby-plugin-react-helmet`,
    {
      resolve: `gatsby-source-strapi`,
      options: {
        apiURL: `http://localhost:1337`,
        queryLimit: 1000,
        contentTypes: [`product`],
      },
    },
    {
      resolve: 'gatsby-plugin-snipcart',
      options: {
        apiKey: 'YOUR_SNIPCART_API_KEY',
        autopop: true,
      },
    },
  ],
}

2. Strapi Setup

Create Content Type:

• Define a Product content type with fields for name, description, price, slug, and image.

Populate Data:

• Add initial product data through the Strapi admin panel.

API Permissions:

• Ensure public access to the product data by configuring API permissions.

3. Fetching and Displaying Data in Gatsby

GraphQL Queries:

• Fetch product data using GraphQL queries in Gatsby.
• Example query for fetching product data:

query {
  allStrapiProduct {
    nodes {
      id
      name
      description
      price
      slug
      image {
        url
      }
    }
  }
}

Product Templates:

• Create templates to display product details.
• Use the fetched data to dynamically generate product pages.

4. Snipcart Integration

Snipcart Button:

• Add Snipcart buttons to product pages for adding items to the cart.
• Example Snipcart button configuration:

<button
  className="snipcart-add-item"
  data-item-id="{product.id}"
  data-item-name="{product.name}"
  data-item-price="{product.price}"
  data-item-url="/product/{product.slug}"
  data-item-description="{product.description}"
>
  Add to Cart
</button>

5. Styling and Testing

CSS Styling:

• Apply CSS to style the site.
