cosmiconfig simplifies configuration file management for JavaScript projects. It searches for configuration files in multiple formats (JSON, YAML, JS, etc.) and locations (project directory, parent directories) using customizable search paths. It consolidates settings from various sources, handling precedence and merging. cosmiconfig streamlines loading configuration, allowing developers to focus on their application logic instead of complex file parsing and lookup routines. It supports caching and provides robust error handling, making it a reliable choice for any Node.js project.
Cosmiconfig's release frequency is highly variable. Initial development saw bursts in 2015 and 2016. Releases continued sporadically until 2023, with peaks in May 2018 and September 2023. Since then, there haven't been any releases.
Cosmiconfig npm package downloads show a generally upward trend from March 2024 to August 2025, peaking in June and July 2025 at over 340 million downloads. September 2025 downloads are significantly lower, but this is partial data.
