npmstyle

Npmstyle is a community-driven style guide and configuration convention for npm packages and Node.js projects. It provides a cohesive set of rules intended to improve consistency and maintainability across packages in the npm ecosystem. Although not an official npm standard, npmstyle focuses on both source code conventions and packaging metadata that affect publishing and reuse.

Core components of npmstyle include guidance on package.json structure and metadata, such as naming, versioning, description, repository, license, keywords, and publishConfig. It also prescribes script naming and usage, recommended devDependencies, and practices for dependency management, semver ranges, and engines fields. For code, npmstyle outlines consistent code formatting, error handling, module import patterns, and testing conventions.

Implementation and tooling: projects adopting npmstyle may adopt a configuration file such as .npmstylerc or npmstyle.config.js to declare rules, alongside linting and formatting tools like ESLint and Prettier, and standard test runners. The style guide typically integrates with continuous integration to enforce checks on package metadata, script correctness, and publish readiness before releasing.

Relation to other standards: npmstyle sits alongside broader JavaScript style guides but emphasizes package publishing and npm-specific metadata. It is compatible with semantic versioning and other npm publishing best practices, and is often used by libraries or boilerplates seeking consistent package quality across multiple contributors.
