v0.12.2

[0.12.2] - 2024-12-27

Added

• Project Configuration Checks in check command - Now scans project configuration in addition to code patterns

  • Separate output sections for "Project Configuration" and "Code Pattern Issues"
  • Severity levels: error (✗), warning (⚠), info (ℹ)

  Configuration checks:

  Check	Severity	Description
  Outdated browserslist	error	Browser targets don't support ?. and ?? (min: chrome 111, edge 111, firefox 111, safari 16.4)
  Babel detected	error	Babel config found (may transpile modern syntax, breaking V8 coverage)
  Playwright not found	error	@playwright/test not in devDependencies (required for nextcov)
  Missing browserslist	warning	No browserslist config - ?. and ?? may be transpiled, causing phantom branches
  Jest detected	warning	Jest config found (consider using Vitest for V8 coverage)
  Source maps not enabled	warning	productionBrowserSourceMaps: true not found in next.config
  Vitest not found	info	Vitest not in devDependencies (recommended for V8 coverage)

• New files:

  • src/linter/detectors/project-config.ts - Project configuration detector
  • src/linter/config-scanner.ts - Configuration scanner wrapper
  • src/linter/detectors/__tests__/project-config.test.ts - Detector tests (20 tests)
  • src/linter/__tests__/config-scanner.test.ts - Scanner tests (7 tests)

• New --skip-config flag for check command - Skip project configuration checks

  npx nextcov check              # config only (no paths)
  npx nextcov check src/         # config + source code
  npx nextcov check src/ --skip-config  # source code only

Changed

• check command behavior - Config is checked by default, source only scanned if paths provided

  • npx nextcov check → config only
  • npx nextcov check src/ → config + source
  • npx nextcov check src/ --skip-config → source only

• check command output - Now shows two sections:

  Project Configuration:
  ─────────────────────────────────────────────────────────
    ✗ Browserslist targets outdated browsers
    ⚠ Jest detected - consider using Vitest for V8 coverage
  
  V8 Coverage Readiness Check
  ═══════════════════════════════════════════════════════════
  ...code pattern issues...
  

• Exit code behavior - Returns 1 if config errors OR code issues found (unless --ignore-patterns)

Tests

• Total tests: 777 passing (up from 742)
• New tests for config detection, scanning, and --skip-config flag
