Pagination

Returning a large collection in smaller pages instead of all at once, using offset or cursor strategies to keep responses fast and bounded.

Evolving an API without breaking existing clients by serving multiple versions, so a breaking change ships as a new version rather than in place.

Data Fetching & API Integration

How a frontend loads data from an API and handles the three states every request has — loading, success, and error — while keeping the UI in sync.
