The `npm config` command is used to manage npm's configuration settings. It allows you to view, set, and delete npm configuration options. These configuration options affect how npm installs packages, resolves dependencies, and performs other operations. The command is invaluable for tailoring npm's behavior to your specific project needs or development environment. You can set configurations globally (affecting all projects) or locally (affecting only the current project).
Configurations stored in different locations override each other based on priority, from command-line arguments to npm defaults. Understanding configuration is essential for efficient npm usage and consistent project builds across different systems.

Modifying the global configuration can impact all projects on your system. Be mindful of the scope when setting configuration values.

npm reads configuration settings from several locations in order of priority:
1. Command line flags.
2. Environment variables.
3. Project .npmrc file.
4. User .npmrc file (~/.npmrc).
5. Global npmrc file (prefix/etc/npmrc).
6. npm's built-in defaults.
