mjs to js converter

[Muxi]

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:

1. Rename the file:
   bash
   ΑντιγραφήΕπεξεργασία
   mv file.mjs file.js
2. In your package.json, add:
   json
   ΑντιγραφήΕπεξεργασία
   {
   "type": "module"
   }
3. 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.

First of all, thank you very much for your feedback. I don't know much about coding and don't have the slightest idea about ES modules/CommonJS. Using the example of lapse.mjs, I saw that someone on Github converted this and other data from the source code to lapse.js.

What exactly would you have to do to convert this type of data? Is there an application or a command line for this? I don't know if you can compare this, but I once had an exe file under Windows that I could convert "bin" to "js". Thanks in advance.

Edit:
It seems to me that only the file extensions have been renamed, as the content and file size of both files are identical.

Good evening. My English is poor and the answer I uploaded is from chatgpt. If you want, you can upload the file to it and it will do the conversion for you.
