TypeScript Exports Module for Node.js

Long Story Short

const func = () => {
    console.log('Hello World');
}

// Export for TypeScript module system
export default func;

// Export for Node.js module system, by doing this you can use `require` to import the module in Node.js 
if (typeof module !== 'undefined') {
    module.exports = Object.assign(func, module.exports)
}
