## What it is
A tiny Node.js configuration loader that merges defaults, config files (JSON or INI), environment variables, and command-line arguments into one object using conventional rc-file lookup locations. It is intentionally non-configurable, requiring only an app name and a defaults object.

## Use cases
- load configuration from rc files in a node cli app
- merge command line args with config files and env vars
- read .apprc style config files with standard lookup paths
- support ini and json config files with comments
- layered configuration with sensible precedence for a nodejs tool

## When to choose
- you want zero-configuration config loading with unix rc-file conventions
- you need a tiny dependency for a CLI tool's settings
- you want config from multiple sources (files, env, argv) merged automatically

## When to avoid
- you need configurable file formats like YAML or TOML
- you need schema validation or typed configuration
- you want full control over lookup paths and precedence rules

## Facets
- artifact type: library
- maturity: maintenance
- function: configuration-management, parser
- domain: developer-tools, backend
- platform: cli, cross-platform
- tags: config-loader, rc-files, ini, json-config, environment-variables, dotfiles, command-line, nodejs, javascript
