Munch Ease — Plan, Cook, Shop, Repeat

Munch Ease is a snappy Vue 3 app that helps you plan meals, manage recipes, and turn plans into stress-free shopping lists. Search and save recipes, build your weekly meal plan, and seamlessly check items off your shopping list—everything stays in sync so you can focus on what’s cooking.

Built with modern Vue patterns, a clean API layer, and lightweight tests, the project is easy to extend and fun to work on.

Quick start

1. Install dependencies

npm install

2. Run the dev server

npm run serve

3. Run unit tests (Vitest)

npm run test

4. Build for production

npm run build

Environment

• API base URL: set VUE_APP_API_BASE (e.g. http://localhost:8081)

---

Architecture and conventions

Strict TypeScript, Vue 3 Composition API, and a single typed API boundary.

Key axioms

• OpenAPI (generated src/api/types.ts) is the single source of truth for shapes.
• SDK (src/api/sdk.ts) is the only data access surface; UI uses domain types from src/domain/types.ts.
• Domain normalization is minimal in src/domain/decoders.ts (e.g., date strings → Date).
• No casts (as, angle brackets) and no any/unknown in app code. Generated files are exempt.
• Arrays that are required in OpenAPI are non-nullable in domain types (e.g., Meal.recipes).
• Disallow runtime type checks in app code; acceptable exceptions: DOM event narrowing, error/env handling in the boundary.

Layout

• src/api/ — Typed client and SDK boundary
• src/domain/ — Domain types and decoders
• src/composables/ — Reusable app logic (auth, meals, shopping, pagination, alert)
• src/components/ — UI components and pages
• src/router/ — Routes and helpers (parseRouteId, parseQueryString)

Testing and tooling

• Vitest + MSW under tests/
• ESLint (type-aware) + Prettier + Volar

Development tips

• Prefer composables for shared logic; keep components thin.
• Use computed for derived values; avoid mutating props directly.
• Use discriminated unions for UI-only shapes when helpful (e.g., shopping Group).
• Add/adjust tests when changing behavior.

---

Troubleshooting

• API errors: verify VUE_APP_API_BASE is set and reachable.
• Type/IDE help: ensure Volar is enabled and ESLint is not conflicting with Prettier.
• Build issues: this project uses Vue CLI 5. If migrating to Vite, update scripts and configs accordingly.

Type checking and codegen

• Type check (TS strict + vue-tsc):

npm run typecheck

• Generate API types (consumed by SDK):

npm run codegen

Environment

• VUE_APP_API_BASE (Vue CLI) or VITE_API_BASE_URL (Vite) for API base URL

Testing

• Unit tests use MSW; the client defaults to a localhost base in tests for easy mocking
