Can you explain how to use ES modules in Node.js?
Sure! ES modules allow you to use the import
and export
syntax in your Node.js applications. You can enable them by either using the .mjs
file extension or by adding "type": "module" in your package.json
.
What is the difference between CommonJS and ES modules?
CommonJS uses require()
and module.exports
, while ES modules use import
and export
. ES modules are more modern and support static analysis.
Can I mix CommonJS and ES modules in the same project?
Yes, but it can be tricky. You can import CommonJS modules in ES modules, but not the other way around. It's best to stick to one module system when possible.
Are there any limitations when using ES modules?
Yes, some limitations include the inability to use __dirname
and __filename
directly. You may need to use the import.meta.url
for similar functionality.
