17-23: Check for valid port values and consider fallbacks
While setting environment-based constants is a great approach, there is a potential scenario whereos.getenv("APP_PORT")might not be a valid integer (e.g. an empty string or a non-numeric string), causing aValueError. You may want to add minimal validation or fallback logic to prevent runtime errors in edge cases.

27-43: Review new class for clarity
The NodePackageManager class correctly identifies different Node.js package managers (pnpm/npm). It’s straightforward and leverages __new__ to create a str subclass. This approach looks good. Consider adding a brief docstring to clarify its purpose for future maintainers.
Line range hint 172-186: Ensure consistent usage of package-manager flags
Line 172 handles the npm-specific flag, which is correct. The updated messages (lines 177 and 186) are clear and user-friendly, making it easier to monitor the frontend startup. No issues here.
203-205: Validate environment usage for backend startup
The backend startup script passes env=envs to include environment variables. This is a good pattern to maintain consistent environment handling. Everything looks fine.
231-231: Front-end installation feedback
Printing out the package manager name is a helpful addition and gives quick clarity to developers.
Line range hint 236-257: Enhanced type-safety for Node package manager detection
Changing the return type from str to NodePackageManager nicely clarifies its usage and sets the stage for future expansions (e.g., adding new properties). This is a solid improvement.

17-23: LGTM! Consider documenting environment variables.The introduction of configurable host and port settings via environment variables improves flexibility. The comments clearly distinguish between the backend port (APP_PORT) and development proxy port (DEFAULT_FRONTEND_PORT).
Consider adding a
.env.examplefile documenting these environment variables and their default values for better developer experience.
27-42: LGTM! Consider adding type hints for property return values.The NodePackageManager class provides a clean abstraction for package manager operations. The use of properties for type checking is elegant and maintainable.
Consider adding explicit return type hints to properties for better code documentation:
@property -def name(self) -> str: +def name(self) -> str: # already has return type return Path(self).stem @property -def is_pnpm(self): +def is_pnpm(self) -> bool: return self.name == "pnpm" @property -def is_npm(self): +def is_npm(self) -> bool: return self.name == "npm"

172-177: LGTM! Proper handling of npm command-line arguments.
The conditional addition of "--" for npm is correct and necessary for proper argument parsing. The updated startup message provides better clarity to users.
186-186: LGTM! Improved user feedback.
The updated message better sets user expectations by indicating that additional time might be needed for the app to be fully ready.
231-231: LGTM! Consistent use of NodePackageManager class.
The message properly utilizes the new NodePackageManager class's name property.
Line range hint 236-257: LGTM! Improved type safety with NodePackageManager.
The function properly implements the new NodePackageManager class while maintaining the same logical flow. The type hints and implementation are consistent.
