YAML File Merger CLI

merge-yaml-cli is a command-line utility for concatenating and merging multiple YAML files into a single output file. It leverages `glob` patterns for flexible input file selection, making it suitable for configuration management in projects with fragmented YAML setups. The package also exposes a Node.js API, allowing programmatic integration into larger JavaScript applications. The current stable version is 1.1.2. Based on its last publish date 8 years ago and limited recent activity, the project appears to be in a maintenance state with infrequent updates. While it provides a core utility, users seeking more advanced merge strategies (e.g., array concatenation vs. deep merging, or specific key-based merging) might need to explore alternatives like `yq` or `yaml-merge` which offer more nuanced control over the merge process.
