Dotenv version 2.0.0 marks a notable update from the previous stable version, 1.2.0, enhancing the development experience for JavaScript projects relying on environment variables. While both versions share the core functionality of loading environment variables from a .env file, several key differences are apparent in their development dependencies and release dates. Version 2.0.0 was released on January 21, 2016, a significant time jump from version 1.2.0's release on June 21, 2015.
The most significant changes reside in the devDependencies. Version 2.0.0 upgrades several tools. Notably, lab jumps to version 5.17.0 suggesting refinements in testing capabilities. New additions include babel (version 5.8.23), most likely enabling support for newer JavaScript syntax during development and standard (version 5.3.0) helping keep a consistent coding style in the project. Version 1.2.0 used older versions of lab, sinon, semver, should, and standard.
For developers choosing between the two, version 2.0.0 offers improved testing and code quality tools which contributes to a better development lifecycle. The utilization of Babel may indicate that the package source code started making use of ES6 syntax making the library more modern. The core functionality remains the same - streamlining configuration by loading environment-specific variables from a .env file, ensuring secure and manageable application settings decoupled from the codebase.
