Create Static Mock JSON:API Endpoint for Testing

[intel352]

Description:
Create a static mock server that provides JSON:API compliant responses for testing the validator.

Requirements:

• Set up a simple mock server (using Express.js or similar)
• Implement endpoints that return valid JSON:API responses:
  • /articles - Collection of articles with relationships
  • /articles/{id} - Single article resource
  • /articles/{id}/author - Related author resource
  • /articles/{id}/comments - Related comments collection
  • /people/{id} - Person resource
  • /comments/{id} - Comment resource
• Include examples of:
  • Compound documents with included resources
  • Pagination links
  • Sparse fieldsets support
  • Sorting capabilities
  • Error responses
  • Meta information
  • JSON:API version object
• Support various query parameters as per spec
• Include both valid and intentionally invalid responses for testing
• Document all available endpoints and their behaviors

Definition of Done:

• Mock server runs locally and responds to requests
• All endpoints return properly formatted JSON:API responses
• Includes comprehensive examples of all spec features
• Documentation clearly explains available endpoints
• Can be used to test both positive and negative validation cases
