I am making a website and I am trying to import a script. Whenever I try to import the script I get Uncaught SyntaxError: Unexpected token '{' . I am using express to show the website and it is just returning a html file.

This is the script tag that I am using to access the main script.

<script type="module" src="./main.js" defer>

This is the code in the main file

.then(function(data) {
    data.forEach(function(currentdevice) {
    import { testvalue } from "./DeviceManager/" + currentdevice.Type;
});

Basically currentdevice.Type is the file name and I checked it is correct.

For the file that I am trying to import I just have a bit of example code why I try to get import to work.

export const testvalue = 'test';

I have looked on google and I was unable to personally find anything.
