Does anyone know of an application to convert "mjs" to "js"?
Or is it enough to simply rename the file extension?
Thanks in advance for any answers.
Yes, you can convert an .mjs file to .js, but it’s not just about renaming the file — it depends on how the code is written.
What is .mjs?
.mjs files use
ES Modules syntax (with import/export). On the other hand, .js files can use either:
- CommonJS (with require and module.exports), or
- ES Modules, if specified in package.json.
How to convert it?
It depends on the environment (Node.js, browser, etc.):
1. Simple rename (if ES Modules are supported)
If the environment supports ES Modules:
- Rename the file:
bash
ΑντιγραφήΕπεξεργασία
mv file.mjs file.js
- In your package.json, add:
json
ΑντιγραφήΕπεξεργασία
{
"type": "module"
}
- Use import/export as normal in your .js file.
2. Convert to CommonJS (if needed)
If the environment doesn’t support ES Modules or you want to use CommonJS:
From .mjs:
js
ΑντιγραφήΕπεξεργασία
import fs from 'fs';
export function readFile(path) {
return fs.readFileSync(path);
}
Convert to .js using CommonJS:
js
ΑντιγραφήΕπεξεργασία
const fs = require('fs');
function readFile(path) {
return fs.readFileSync(path);
}
module.exports = { readFile };
Summary
- Yes, you can convert .mjs to .js.
- If using ES Modules, just rename and update package.json.
- If converting to CommonJS, change the syntax accordingly.
