service-interceptor	Creates API service wrappers that simulate network calls with artificial delays and error rates for robust UI testing (no backend required).	MIT	create api service mock fetch calls simulate network delay

Service Interceptor

When to use this skill

• Use when UI needs to consume an API-like interface while the backend is absent.
• Triggered by prompts to mock axios/fetch behavior or to add latency/failure simulation.

Instructions

1. First Step: Implement src/services/api.ts exporting functions (getPapers, getPaperById, searchPapers) that return Promises and optionally use setTimeout to simulate delay.

2. Second Step: Make the delay configurable; expose a setMockDelay(ms) helper and an optional errorRate flag for testing error states.

3. Third Step: Use mockData fixtures as response payloads and ensure the services return the same shape as a future real API.

Examples

• await api.getPapers({ page: 1, pageSize: 10 }) // resolves after 300ms with { items, total }

Notes

• Document how to switch to a real API endpoint later by replacing the service implementation or toggling an environment variable.
