Requirements: Node.js >= 18.20.5
# Install dependencies
npm install --legacy-peer-deps
# Start dev server
npm run docs:devVisit http://localhost:1000/java-doc/
Switch between flat and dropdown navigation by editing .env:
# .env
NAVBAR_STYLE=dropdown # grouped dropdown (default)
NAVBAR_STYLE=flat # all modules expanded flatThe CI/CD build always reads from .env, no extra config needed.
# Production build
npm run docs:build
