How to import class using ES6 syntax? (without Babel)

can i use es6 without babel
why use babel with node
npm esm
import not working in node
node.js import
es6 import
node commonjs import
node v13 import

I have file with a ES6 class with default export:

accessmanager.js

   export default class AccessManagerClient {
      constructor(){
        ...
      }
    }

And I want to import it like this:

anotherFile.js

import AccessManagerClient from '../someFolder/accessmanager';

When I run my spec I get an error:

import AccessManagerClient from '../someFolder/accessmanager';
^^^^^^

SyntaxError: Unexpected token import

I have such npm and node versions:

$ npm -v
5.3.0

$ node -v
v8.0.0

You can't without Babel or some other packager/bundler/transpiler, because Node doesn't have native support for import/export yet. Either use Node's own modules, or a packager/bundler/transpiler.

Its now August 2017, can I use ES6 without Babel?, ? Absolutely. But, if high compatibility with every damn browser out there is a priority for you, then you should consider transpiling a version for those platforms, or just stay with transpiling everything for a while longer. We require use Babel.js to arrange it to the code Node.js backings and run it by utilizing npm run-script run, and you can see it works. In the code beneath, we utilize import * as calc, which implies it will import all variables this module sends out, as properties of calc. On the other hand we can simply import a few variables we need and utilize then as independent variables as beneath.

I know that this is an old question. But in case others still look for alternative, now with the new Node version, we can use without Babel:

  • Not possible to work with import and export without babel (or another transpiler that does the same as babel). You can use old school const AccessManagerClient = require('...'); The more interesting question is, why not use babel?
  • thank you for your help
