VFile Message Statistics Utility

vfile-statistics is a lightweight utility within the unified ecosystem designed to categorize and count messages associated with `vfile` instances. It provides statistics such as the total number of messages, as well as counts for fatal errors, warnings, and informational messages. The current stable version is 3.0.0, which notably requires Node.js 16 or higher and is an ESM-only package. This library follows the release cadence of the broader unified collective, tying major version bumps to Node.js LTS updates and significant changes in its peer dependencies like `vfile`. Its key differentiator is its focused simplicity, serving as a composable building block for tools processing virtual files, rather than a standalone, opinionated linter or parser.
