Migration Notes (v0 → v1)

If you are upgrading from json-server v0.x, note these behavioral changes:

• ID handling: id is always a string and will be auto-generated if not provided
• Pagination: Use perpage with page instead of the deprecated limit parameter
• Relationships: Use embed instead of expand for including related resources
• Request delays: Use browser DevTools (Network tab > throttling) instead of the removed --delay CLI option

Pagination

Notes: - perpage defaults to 10 if not specified - Invalid page or perpage values are automatically normalized to valid ranges
