To configure native ES Modules in a TypeScript project, you need to update your package.json and tsconfig.json settings. This skill provides exact configurations and patterns for setting up ESM syntax, ensuring proper file extensions and tree-shakeable code.

Correct ESM syntax involves using named and default imports and exports. This skill demonstrates preferred patterns for structuring import/export statements, including re-exports, to ensure clean and maintainable ECMAScript Module code.

Importing Node.js built-in modules in ESM requires using the node: prefix for clarity and native compatibility. This skill covers Node.js specifics including built-in module usage and handling CommonJS interop.

ESM supports CommonJS interop in Node.js through specific import patterns. This skill addresses how to handle CommonJS dependencies within a native ES Module setup, enforcing ESM-only principles to avoid common integration mistakes.

Common ESM anti-patterns include incorrect file extensions, improper package.json configuration, and mismanaged default exports. This skill identifies these frequent mistakes and provides the correct modern ECMAScript Module patterns to avoid them.
