confbox

confbox is a utility library for parsing and serializing various configuration file formats, including YAML, TOML, JSONC (JSON with Comments), JSON5, INI, and standard JSON. The current stable version is 0.2.4, and the package maintains an active development cadence, releasing minor updates and patches regularly. Key differentiators include its claim of zero runtime dependencies for the end-user, tree-shakability for efficient bundling, and out-of-the-box TypeScript type definitions. It also features logic to preserve code style, such as indentation and whitespace, for certain formats during round-trip parsing and stringifying. While it wraps several established parsing libraries internally, it presents a unified, simplified API. For more complex configuration loading scenarios, the unjs/c12 library is recommended as an alternative.
