npmstyleconfigjs

npmstyleconfigjs is a JavaScript-based configuration standard and tooling designed to manage npm-style configuration for Node.js projects. It provides a structured approach to defining, resolving, and validating settings in a single source of truth, while remaining compatible with existing npm conventions such as script entries, registry and proxy settings, and environment-specific overrides.

The core concept is a JavaScript module or file that exports a configuration object or a resolver function. Implementations typically live in a file named npmstyleconfigjs.js or under a dedicated package called npmstyleconfigjs, and can be consumed by build tools, CLI utilities, or application code. The configuration surface can be defined either as a plain object or as a function that returns an object, enabling dynamic computation based on environment, CLI flags, or other inputs.

Resolution and merging logic usually involve reading default values, merging with project package.json config fields, npmrc settings, and environment variables. Validation and type checking can be provided via a schema to ensure required keys are present and values are within allowed ranges. It often supports environment-specific overrides and lazy evaluation for performance and flexibility.

Usage and interoperability: The approach is designed to integrate with common JavaScript ecosystems, including testing, linting, and bundling tools. It can export a normalized configuration that other tools can consume, reducing duplication and enabling consistent behavior across projects and monorepos.

History and scope: While not part of the official npm project, npmstyleconfigjs represents a community-driven pattern for organizing npm-like settings in JavaScript-friendly form. See also npm, package.json, npmrc, cosmiconfig.
