Publint identifies potential issues in your npm package before publishing. It analyzes your package.json and related files, flagging problems like missing dependencies, incorrect file references, and TypeScript configuration errors. This proactive approach prevents common publishing pitfalls, ensuring a smoother experience for both you and consumers of your package. Using Publint helps improve your package's quality, discoverability, and overall usability within the npm ecosystem. It's a great tool for maintaining package integrity.
