NodeJS Ambiguity Sometimes – Import, Export, CommonJS, and ES Modules
NodeJS Ambiguity — .mjs, CommonJS, and ES Modules The .mjs extension is used for JavaScript modules in the ECMAScript (ES) module format. Below are key points to help you navigate the often-confusing landscape of CommonJS vs ES Modules in Node.js. 1. Module Syntax Files with the .mjs extension allow you to use modern import and export statements, enabling modular programming in JavaScript. This provides a standardized way to manage dependencies and organize code. 2. Differentiation from .js While .js files can be used for both CommonJS ( require/module.exports ) and ES modules, .mjs explicitly indicates that the file is an ES module. This explicitness helps avoid ambiguity in environments that support both module types. 3. Browser and Node.js Support Modern browsers and Node.js support the .mjs extension. In Node.js you can alternatively set "type": "module" in pac...
