Blueconfig

Blueconfig v6.2.2 is a configuration schema validator and loader for Node.js, forked from node-convict v5. It merges configs from files (JSON, YAML, JSON5, TOML, XML) and environment variables, applying schema validation with custom formats and coercion. Key differentiators: supports multiple config sources, sensitive data masking, environment variable overrides, command-line argument mapping, and custom file format parsers. Release cadence is irregular; maintained by a single developer. Active development with upcoming v7 aiming to reduce dependencies.
