Exercise data
This is a source-backed implementation overview. The repository contains tests; no conversion, client-outcome, or load-test results are claimed here.
Keeping search responsive
The library hook defers the search value and uses AbortController to cancel requests when the query changes. It checks for stale responses before updating state and exposes loading, error, and pagination state to the interface.
Exercise library hookSeparating the API from presentation
An API service builds requests, checks responses, caches results in memory, and maps ExerciseDB data into the application model. Caching avoids repeated requests during a session; it also creates a freshness tradeoff because cached entries have no expiry.
Exercise API serviceTesting the transformation boundary
Focused tests cover mapping exercise fields, formatting names, and sorting category options. The modal implementation also handles Escape and restores page scrolling after close. Further validation should cover rapid filter changes, API failures, and complete keyboard focus management.
