node-config is a Node.js library that organizes hierarchical application configurations across deployment environments like development, QA, staging, and production. It stores defaults in config files and allows overrides via environment variables, command-line parameters, or external sources.

Use cases

• manage per-environment settings for a Node.js app
• override config values with environment variables in production
• load JSON or YAML configuration files in Node.js
• share a consistent config interface across npm modules
• separate dev and production database settings
• read nested config values with get and has helpers

When to choose

• you need hierarchical, environment-aware configuration for a Node.js application
• you want file-based defaults with environment variable and CLI overrides
• you need a lightweight, widely adopted config solution with multi-format support

When to avoid

• you are not using Node.js
• you need remote dynamic config with a hosted control plane like LaunchDarkly or Consul KV
• you only need simple dotenv-style key-value environment loading
