Mock Package (@vup/mock)

@vup/mock provides an MSW-based mock layer for development and integration.

What It Solves

• Enables frontend-first delivery before backend is ready
• Keeps request paths stable between mock and real API
• Makes edge-case and error-path testing easier

Typical Scenarios

• Parallel frontend/backend development
• Temporary simulation for unstable APIs
• Reproducible QA and demo environments

Recommended Usage

1. Keep API function signatures unchanged
2. Toggle mock by environment switch
3. Remove ad-hoc inline fake data from business code
