Winston provides enterprise-grade logging for Node.js applications with multiple transports, custom formatting, and flexible log level management. As the creator of CoreUI, a widely used open-source UI library, I’ve implemented Winston logging in Node.js production services throughout my 11 years of backend development. The most effective approach is configuring Winston with console and file transports for comprehensive logging. This method enables simultaneous logging to multiple destinations with different formats and levels.

Managing separate configurations for development and production is crucial for Angular applications with different API endpoints, feature flags, and debug settings. As the creator of CoreUI with over 11 years of Angular development experience since 2014, I’ve configured production deployments for countless enterprise applications. The most effective solution is to use Angular’s environment file replacement system that automatically swaps configurations during build. This approach ensures clean separation between environments without manual configuration changes.
