## What it is
publint is a linter that checks npm packages for packaging errors, ensuring compatibility across environments like Vite, Webpack, Rollup, and Node.js. It can be run as a CLI via npx, integrated into CI workflows, or used online at publint.dev.

## Use cases
- lint npm package packaging errors
- check package.json exports configuration mistakes
- verify library compatibility with bundlers and node
- add package linting to CI before publishing
- audit a published npm package for packaging issues

## When to choose
- you publish npm packages and want to catch packaging mistakes before release
- you maintain a library consumed by multiple bundlers and runtimes
- you want automated checks of exports, files, and package.json best practices

## When to avoid
- you need general JavaScript code linting (use ESLint instead)
- your project is not an npm package
- you use Yarn 1, which is explicitly unsupported

## Facets
- artifact type: cli-tool
- maturity: active
- function: linter, cli, developer-tools, package-manager
- domain: developer-tools, web-development
- platform: cli, cross-platform
