How to convert CommonJS to ESM

ECMAScript modules (ESM) are the modern standard for writing JavaScript, supporting features like async loading and better compatibility. This post guides you through updating the syntax of a legacy CommonJS project to ESM, including changes in import/export statements and package.json configurations. Removing 'use strict' and using shims for globals like __dirname and __filename are also discussed. Tools like VSCode and various npm packages can assist in the transition. Adopting ESM can alleviate compatibility issues and streamline development.
