As the creator of CoreUI and with over 25 years of software development experience, I’ll show you how to effectively use dotenv to manage environment variables in your applications.

Cloning Git repositories with SSH provides secure authentication and encrypted data transfer without requiring password input for each operation. As the creator of CoreUI, a widely used open-source UI library, I’ve set up SSH authentication for thousands of developers across our open-source and enterprise projects. From my expertise, the most effective approach is using SSH keys with git clone for secure and convenient repository access. This method eliminates password prompts while providing stronger security through public-key cryptography for all Git operations.

Managing configuration and sensitive data through environment variables is essential for secure and flexible Node.js applications across different deployment environments. As the creator of CoreUI, a widely used open-source UI library, I’ve implemented environment variable management in numerous Node.js backend services for API keys, database connections, and deployment-specific configurations. From my expertise, the most secure approach is to use process.env with the dotenv package for local development. This method keeps sensitive data out of source code while providing easy configuration management across development, staging, and production environments.
