How ivan-kulagin/vdnh-test works
<explanation>
1. Identify the project type and purpose
- This is a Nuxt 3‑based frontend application (SSR/SSG) for rendering an event “afisha” board with categories, filters, and date sliders, with full i18n support. There is no proprietary backend code here—API calls are forwarded to external category and event services.
2. Analyze the file structure
- Top‑level files:
• nuxt.config.ts, package.json, tsconfig.json → overall framework and build config
• README.md → usage and deployment instructions
• .github/workflows/deploy.yml → CI/CD pipeline
• public/ → static assets (fonts, images)
• config/i18n → internationalization setup
• server/tsconfig.json → placeholder for server middleware or server functions
- src/ folder is layered by responsibility:
• src/app → application shell (layout.vue, global styles)
• src/entities → domain models (category, event) + their API clients
• src/features → business‑level features (e.g., event filtering logic)
• src/pages → route‑level entry points (e.g., /russia)
• src/widgets → reusable UI widgets (afisha board, date slider, title)
• src/shared → cross‑cutting UI elements (icons, sliders), types, utilities
3. Examine the README for additional insights
- It confirms standard Nuxt 3 usage (dev, build, preview).
- No diagram or high‑level architecture; it delegates hosting and SSR to Nuxt.
4. How to draw an accurate system design diagram
a. Main components
1. Client Browser
2. CDN / Static Asset Server (serving public/, built JS/CSS)
3. Nuxt 3 Server (SSR/SSG engine)
– config/i18n
– src/app (layout & global styles)
– src/pages → routes
– src/features → business logic
– src/entities → API clients
– src/widgets & src/shared → UI components
4. External Category & Event APIs (third‑party or backend microservices)
5. CI/CD Pipeline (GitHub Actions → deploy to hosting)
b. Relationships & interactions
- Browser requests route → Nuxt 3 Server SSRs the page → returns HTML + JS/CSS.
- At runtime, client‑side hydration makes API calls via src/entities/**/api to external APIs.
- Static assets (fonts, images) routed through CDN/asset server.
- Git pushes trigger CI/CD → build → deploy to hosting (Vercel/Netlify).
c. Architectural patterns
- Modular directory‑based separation (feature‑driven & domain‑driven design).
- Component‑based UI (widgets & shared components).
- Layered application shell (app → pages → features → entities → api).
- SSR/SSG pattern with dynamic client hydration.
d. Key technologies & libraries
- Vue 3 + Nuxt 3 (SSR, routing, SSG)
- TypeScript, SCSS modules
- i18n (config/i18n folder)
- Swiper for sliders (src/shared/ui/slider)
- GitHub Actions for CI/CD
5. Tailoring the diagram to this full‑stack-like SSR application
- Emphasize SSR server vs. static asset server vs. client hydration boundary.
- Show how config/i18n plugs into the Nuxt engine at startup.
- Illustrate the src folder layers as distinct logical zones.
- Highlight external API dependency (no in‑repo database).
- Include CI/CD flow as a side process feeding into the deployment target.
6. Diagramming guidelines
- Use clear rectangular boxes for each component: Browser, CDN, Nuxt Server, External APIs, CI/CD.
- Label internal sub‑layers inside the Nuxt Server box (app, pages, features, entities, widgets, shared).
- Draw directional arrows:
• Browser → Nuxt Server (page request)
• Nuxt Server → Browser (HTML + assets)
• Browser (hydration) → External APIs (category/event fetch)
• GitHub → CI/CD → Hosting
- Use color coding or shapes:
• Blue for frontend/UI layers
• Green for business logic layers (features, entities)
• Orange for external dependencies (APIs, CI/CD)
• Grey for static assets/CDN
7. Emphasis on detail
- Capture every folder’s role as a component or sub‑component.
- Do not lump all UI under “frontend”—instead break out widgets, shared, features, entities.
- Show how i18n configuration flows from config/i18n into the rendering pipeline.
- Indicate build and deploy steps separately from runtime traffic flows.
By following these steps and structuring your diagram with clear labels, directional arrows, and color‑coded zones, you will provide a comprehensive, instantly understandable architecture overview tailored specifically to this Nuxt 3 Minimal Starter project.
