Move LQIP functionality from GraphQL queries into API client

[Copilot]

This PR centralizes Low Quality Image Placeholder (LQIP) functionality by moving it from individual GraphQL queries into the API client, eliminating the need for manual urlTemplate(lossy: true) parameters throughout the codebase.

Problem

Previously, LQIP functionality was scattered across 15+ GraphQL fragments and queries, requiring developers to manually add lossy: true parameters:

# Before - manual lossy parameter in every query
image {
  url: urlTemplate(lossy: true)
}

This approach had several issues:

• Inconsistent application across queries
• Code duplication and maintenance burden
• Easy to forget when adding new image queries
• No centralized control over LQIP settings

Solution

The LQIP functionality is now centralized in the API client with automatic image URL transformation:

// Client configuration with LQIP settings
export const client = createClient({
  imageTransforms: {
    enableLossy: true,
    lossyQuality: 30,
  },
  // ... other config
});

# After - clean queries without manual parameters
image {
  url: urlTemplate
}

Implementation Details

API Client Enhancement

• Added ImageTransformOptions interface for configurable LQIP settings
• Created transformImageUrls() utility that recursively processes GraphQL responses
• Integrated automatic transformation in the client's fetch method
• Smart detection only transforms BigCommerce CDN URLs, leaving external URLs unchanged

Response Processing

The client now automatically transforms image URLs in GraphQL responses:

Input:  https://cdn11.bigcommerce.com/s-123abc/products/123/images/456/image.jpg
Output: https://cdn11.bigcommerce.com/s-123abc/products/123/images/456/image.jpg?lossy=true&quality=30

GraphQL Query Cleanup

Removed urlTemplate(lossy: true) parameters from all fragments and queries across:

• Product pages and schemas
• Cart items (physical and digital)
• Blog post images
• Header/footer/store logo fragments
• Product cards and comparison features
• Account order history

Benefits

1. Centralized Control: All LQIP logic is now in one place, making it easy to adjust quality settings or disable LQIP entirely
2. Cleaner Queries: GraphQL fragments are simpler and more maintainable without manual lossy parameters
3. Consistent Behavior: All BigCommerce CDN images automatically get LQIP treatment
4. Type Safety: Full TypeScript support with proper interfaces and exports
5. Non-destructive: Original GraphQL response data is not mutated

Testing

Added comprehensive test suite covering:

• URL transformation for various BigCommerce CDN patterns
• Nested object and array processing
• Configuration options (quality settings, enable/disable)
• External URL preservation
• Edge cases (null/undefined values)

The implementation has been verified to maintain all existing functionality while providing the new centralized LQIP capabilities.

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• googlechromelabs.github.io
  • Triggering command: node install.mjs (dns block)

  • Triggering command: node install.mjs (http block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)

Fixed all lint failures in the client package where the LQIP changes were made. The remaining TypeScript errors in the core package are pre-existing issues unrelated to the LQIP implementation (verified by testing with/without the LQIP configuration).

Changes made:

• ✅ Fixed import order and sorting issues
• ✅ Added proper JSDoc comments with parameter types
• ✅ Improved type safety by replacing any with unknown
• ✅ Fixed all prettier formatting issues
• ✅ Added eslint overrides for test files
• ✅ Client package now passes lint with zero warnings

The LQIP functionality is working correctly with proper type safety and code quality standards. Commit: 0f99061
