Add `--rails-env` option to `bin/dev prod` for custom Rails environment during assets:precompile - Default: NODE_ENV=production, RAILS_ENV=development (avoids credentials complexity) - Option: `--rails-env=production` for full production Rails environment - Clear documentation that option only affects assets:precompile, not server processes ## Enhanced Documentation - Comprehensive help text with examples and environment explanations - Clear runtime messaging about environment configuration - Separation of asset precompilation vs server process environments - Guidance on when to use each option ## Usage Examples ```bash bin/dev prod # Default: production webpack, development Rails bin/dev prod --rails-env=production # Full production environment bin/dev prod --route=dashboard # Custom route in URLs ``` ## Benefits - ✅ Production webpack optimizations without production Rails complexity by default - ✅ Option for full production environment when needed (testing credentials, etc.) - ✅ Clear documentation prevents confusion about scope -
