Error exporting React Components in index.js file

Question

At some point, I was able to create an index.js file in all of my directories (components, stores, etc.) that exported all my components like this for easy access:

export ComponentA from './ComponentA/ComponentA';
export ComponentB from './ComponentB/ComponentB';
export ComponentC from './ComponentC/ComponentC';

Then I would only import the classes that I need from another file, such as

import { ComponentA, ComponentC } from './components';

For some reason, now I get an error message and don’t know why

ERROR in ./app/containers/index.js
Module build failed: SyntaxError: /Users/abritez/Documents/Projects/React-LTI-Toolprovider/app/containers/index.js: Unexpected token (1:7)

Answer 1

Maybe this is due to the fact that this is not a default export, or a way to pass your code?

If you export only one Widgets, try:

import Widgets from './Widgets/Widgets';
export default Widgets;

Answer 2

:

:

export { default as ComponentA } from "./ComponentA";

ComponentA

export default ComponentA;

MultiComponents , :

export { ComponentB, ComponentC };

:

export { ComponentB, ComponentC } from "./MultiComponents";
