Codebase Context: acme-storefront

Executive Summary

  • Repo shape: Monorepo with one customer-facing web app, one API service, and shared packages.
  • Primary purpose: An e-commerce platform with a React storefront and a Node-based backend.
  • Best place to start reading: apps/storefront/src/main.tsx for frontend bootstrap and apps/api/src/server.ts for backend bootstrap.
  • Confidence: High

Tech Stack

  • Languages: TypeScript, JavaScript, SQL
  • Frameworks: React, Express
  • Build and package tools: pnpm workspaces, Vite
  • Test frameworks: Vitest, Playwright
  • CI or release signals: GitHub Actions workflows for test and deploy

Structure

  • apps/storefront/ - Customer-facing web application
  • apps/api/ - Backend API and service orchestration
  • packages/ui/ - Shared UI components
  • packages/config/ - Shared linting and TypeScript configuration
  • .github/workflows/ - CI definitions for validation and deployment

Entry Points

  • apps/storefront/src/main.tsx - Confirmed frontend bootstrap, High confidence
  • apps/api/src/server.ts - Likely backend process entry, High confidence
  • apps/storefront/src/router.tsx - Likely route definition surface, Medium confidence
  • packages/ui/src/index.ts - Shared package export barrel, High confidence

Dependencies

  • External: react - Frontend rendering model and component architecture
  • External: express - Backend routing and middleware shape
  • External: playwright - Browser-level end-to-end validation
  • Internal: packages/ui - Shared component dependency for the storefront
  • Internal: packages/config - Shared configuration that standardizes tooling across packages

Test Coverage

  • Evidence found: vitest.config.ts, playwright.config.ts, unit tests under apps/storefront/src/**/*.test.tsx, and e2e specs under tests/e2e/
  • Covered areas: Shared UI components and major storefront flows appear to have direct test coverage
  • Weak or unknown areas: API route coverage is unclear from the sampled files, and no coverage report was inspected

Conventions

  • File naming: Mostly kebab-case for files and directories
  • Symbols and types: PascalCase for React components, camelCase for functions and variables
  • Architectural style: App-and-packages monorepo with shared configuration and explicit package boundaries
  • Notes for downstream changes: Preserve package boundaries and prefer updating shared UI through packages/ui instead of duplicating components in the app

Risks and Unknowns

  • API ownership boundaries may be broader than the sampled backend files suggest
  • Route-level auth and payment flows were not deeply inspected
  • Coverage quality is inferred from test presence, not a verified coverage report

Recommended Next Steps

  1. Inspect the API route registration path to confirm service boundaries and middleware order.
  2. Review CI workflows to see which packages are required for merge and release.
  3. Validate whether auth and checkout flows have dedicated e2e coverage before refactoring.
