How does it handle different package types within a monorepo?

It categorizes packages based on their directory (e.g., core packages, vite-plugins, or demos) and applies specific naming and private/public rules for each type.

Which configuration files does this skill validate?

The skill specifically targets package.json, tsup.config.ts, and tsconfig.json to ensure they follow consistent monorepo-wide standards.

Does it support the TypeScript 'exports' field best practices?

Yes, it enforces that 'types' are always listed first in conditional exports to ensure correct resolution by the TypeScript compiler.

Can it assist with internal monorepo dependencies?

It validates that internal references use the 'workspace:^' protocol and ensures new packages are correctly declared in the root package.json.

Developer Tools

Standardizes and validates Node.js package configurations including package.json, tsup, and tsconfig within monorepo environments.

The Package Linter skill is designed to maintain structural integrity and configuration consistency across complex Node.js monorepos. It automates the validation and normalization of essential configuration files, ensuring that all sub-packages adhere to strict naming conventions, field ordering, and build patterns. By enforcing unified standards for publishing metadata, export maps, and TypeScript inheritance, this skill significantly reduces the manual overhead and potential for error when creating, auditing, or updating packages within a shared repository architecture.

Key Features

01Enforcement of tsconfig.json inheritance patterns from monorepo bases

02Validation of tsup.config.ts build settings and entry point consistency

033 GitHub stars

04Verification of workspace dependency protocols and root-level synchronization

05Normalization of publishing configurations (author, license, registry, and access)

06Automated package.json field sorting and mandatory field validation

Use Cases

01Standardizing export maps (ESM/CJS) and type definitions across multiple library packages

02Auditing existing packages for compliance with monorepo standards prior to production releases

03Initializing new sub-packages with pre-configured boilerplate and correct directory structures
