It seems like you’re facing an error related to the use of the import statement in JavaScript. This error occurs when you’re trying to use ECMAScript modules (ESM) syntax in a script that is not recognized as a module.

To resolve this issue, follow these steps:

  1. Make sure you’re using a modern browser or a version of Node.js that supports ECMAScript modules (for example, Node.js v12.17.0 or later).
  2. Update your HTML file to include the type="module" attribute on your script tag. This tells the browser that your script uses ESM syntax:

HTML

<!DOCTYPE html>
<html>
  <head>
    <meta charset="UTF-8" />
    <title>My App</title>
  </head>
  <body>
    <script type="module" src="main.js"></script>
  </body>
</html>
  1. In your JavaScript file, use the import statement to import the required module:

JS

// main.js
import myFunction from './myModule.js';

myFunction();
  1. Ensure that the exported module uses the correct ESM syntax:

JS

// myModule.js
export default function myFunction() {
  console.log('Hello, world!');
}

If you’re using Node.js, you need to specify the module type in the package.json file as well:

JSON

{
  "name": "my-app",
  "version": "1.0.0",
  "type": "module",
  "main": "main.js",
  "scripts": {
    "start": "node main.js"
  },
  "dependencies": {}
}

By following these steps, you should be able to use the import statement without encountering the “Cannot use import statement outside module” error.
