How to import everything exported from a file with ES2015 syntax? Is there a wildcard?

by

You cannot import all variables by wildcard for the first variant because it causes clashing variables if you have it with the same name in different files.

//a.js
export const MY_VAR = 1;

//b.js
export const MY_VAR = 2;


//index.js
import * from './a.js';
import * from './b.js';

console.log(MY_VAR); // which value should be there?

Because here we can’t resolve the actual value of MY_VAR, this kind of import is not possible.

For your case, if you have a lot of values to import, will be better to export them all as object:

// reducers.js

import * as constants from './constants'

console.log(constants.MYAPP_FOO)
