The Node.js team has recently released version 20.6.0, which brings improvements in environment variable configuration, module resolution, module customization, and experimental support for C++ garbage collection.
In this patch, developers gain a new feature: built-in support for `.env` files. These files, following the INI file format, offer a simplified approach to configuring environment variables. Developers can easily initialize their applications with predefined configurations using a straightforward CLI command, `node –env-file=config.env index.js`. This update streamlines the management of environment variables.
