How do I use ES modules in Node.js?
An example of an AI chatbot conversation about using ES modules in Node.js.
How do I use ES modules in Node.js?
You can use ES modules in Node.js by using the .mjs file extension or by setting "type": "module" in your package.json. This allows you to use import and export syntax.
Can you show me a simple example?
Sure! Create a file named module.mjs with the following content: export const greet = () => 'Hello, World!';. Then, in another file, you can import it using import { greet } from './module.mjs';.
What if I want to use it in a .js file?
You can set "type": "module" in your package.json, and then you can use the import and export syntax in your .js files.
Are there any limitations I should be aware of?
Yes, some Node.js features like __dirname and __filename are not available in ES modules by default. You may need to use import.meta.url to work around this.
