I have been unable to make named export/import work outside of the Codecademy environment. I am using Safari 12 and Chrome 71 on MacOs with similar results - these browsers should work. The console message has not been helpful: SyntaxError: Unexpected token '{'. import call expects exactly one argument. (only Safari adds this detail about expecting exactly one argument)

This is one of my attempts:

<!DOCTYPE html>

  <title>Module Test</title>
  <script type="text/javascript" defer src="sandbox.js"></script>

  <p id='textElement'>unchanged</p>



import {changeText} from '/sandbox_module.js';

const textElement = document.getElementById('textElement');



export const changeText = function(elem) {
  elem.textContent = 'changed';

What am I missing here?

Hi @markmacleod988810228 is it maybe because the import should be from


and not


Thanks, @textninja83556 for paying attention to the details. I checked back on this code and I presently I have the form


It’s been weeks since I touched this, and I think I was trying any syntax variation to get it to work. I have learned a few things since I made this post. First, script type needs to be "module" not "text/javascript". And second, the main script file needs a header to allow it to talk to other JS files:

Header Set Access-Control-Allow-Origin: *

To be clear, the wildcard is not a robust use of the header - I just wanted to play with modules outside of Codecademy. None of this was covered in the Codecademy lesson because it didn’t cover using modules with an actual website. Unfortunately, despite making these changes, I still cannot make modules work on my machine. I found one forum that said modules don’t work on locally sourced files due to some security vulnerability (or something - sorry I don’t have a link). After reading that, I gave up, hoping this will be covered later (I’m not optimistic though).

Have you been able to get modules to work outside of Codecademy?
