A full version history of the dotenv package with size, number of distributed files and dependency evolution.
dotenv is a ubiquitous npm package essential for managing environment variables in JavaScript projects. Its version history showcases a steady evolution from its initial release in 2013 to present, adapting to the evolving JavaScript ecosystem and developer needs.
The early versions (0.0.x to 0.5.x) laid the foundation, providing basic .env file parsing capabilities. The shift to 1.x.x versions marked a significant milestone with enhanced stability and feature sets, alongside updated dependencies. Major version bumps like 2.0.0, 3.0.0, 4.0.0, 5.0.0, 6.0.0, 7.0.0, 8.0.0, and so on all the way up to 17.x.x introduced breaking changes and significant improvements, often coinciding with updates to testing frameworks (mocha -> tap), linting rules (standard), and build tools, reflecting best practices on development tools.
Later versions (9.0.0 onwards) focused on refining existing features, improving type safety through TypeScript integration, and addressing security concerns, with funding through dotenvx.com to ensure it gets the resources it needs to maintain quality. The continuous stream of minor and patch releases demonstrates ongoing efforts to provide stability, bug fixes and security enhancements.
