What is the correct syntax to import both default
and named resource from an ES6 JavaScript module?
Example:
export const defaultBrowser = 'Chrome';
export default [
{ value: 0, label: defaultBrowser },
{ value: 1, label: 'Firefox' },
{ value: 2, label: 'Safari' },
{ value: 3, label: 'Edge' },
];
How would one import
that in one go?
It is not a duplicate of When should I use curly braces for ES6 import?, it is more specific, asking for a single import
use-case, and not an import
essay.
Using Named and Default Exports at the same time: It is possible to use Named and Default exports in the same file. It means both will be imported in the same file. Example: javascript.
Exports without a default tag are Named exports. Exports with the default tag are Default exports. Using one over the other can have effects on your code readability, file structure, and component organization. Named and Default exports are not React-centric ideas.
To conditionally import an ES6 module with JavaScript, we can use the import function. const myModule = await import(moduleName); in an async function to call import with the moduleName string to import the module named moduleName . And then we get the module returned by the promise returned by import with await .
There are two different types of export, named and default. You can have multiple named exports per module but only one default export.
The correct syntax to import both default
and named exports from ES6 module is to pass the default
name (whatever one wants), and named, not-default modules separated by a comma:
Example: index.js
import browsers, { otherValue } from './browsers';
in an exemplary file tree:
.
└── src
├── browsers.js
└── index.js
Often encountered real life example:
import React, { useState, useEffect } from 'react';
