Tutorial: publishing ESM-based npm packages with TypeScript

This tutorial explains a modern setup for publishing npm packages with TypeScript and native ESM support. It covers the file system layout, tsconfig.json configuration, package.json settings, unit testing strategies, and how to handle self-referencing in a package. The guide is intended for packages that prioritize modern ESM compatibility over backward compatibility with older CommonJS systems.
