How do I call a function which is stored in an other function?

I created two js files (File A and File B). In file A I created a function called "getFiles" and I would like to call this function in File B.

File A:

export function getFiles(input){
    ...
}

File B:

import {getFiles} = from './A.js';

getFiles('');

But I'm getting the error message "Module '"./A.js"' has no exported member 'getFiles'."

Does anyone know how I can call the function in File B?

• Provide code of what you have tried? – Sean Commented Jun 22, 2020 at 5:46
• which web pages have you read about export in JavaScript? – rioV8 Commented Jun 22, 2020 at 6:04
• why do you post images of code, do you expect us to type it all in, and this is not searchable by SO or Google – rioV8 Commented Jun 22, 2020 at 6:41
• why don't you load/import the file the same as you do for vscode? – rioV8 Commented Jun 22, 2020 at 6:42

You can use import/export.

For example:

file A.js:

export function func1(){

...

}

file B.js:

import { func1 } from './A.js';
... 
func1();

In the js File A I had to create a class to be able to export the function. The class had to be exported with "module.exports"

module.exports = class A {
    getFiles(input) {
        ...
    }
}

And now in File B I had to add a require line to this class:

const A = require('./A.js');

And now I can call my function "getFiles" from File A:

// vscode extension function
function activate(context) {
    const a = new A();
    a.getFiles('');
}
