ES6 - Convert from 'require' to 'import'

问题:

If the alternative to:

 var Foo = require('foo'); 

is:

 import Foo from 'foo'; 

What is the alternative to:

var Bar = require('foo').batz 

Could it be:

import {batz}  from 'foo' ? 

回答1:

Nearly. It does however depend on how you are exporting them.

• named exports (export var batz = …):

  import {batz as Bar} from 'foo'; 

• default-exported object (export default {batz: …};) - should not be used:

  import Foo from 'foo'; var Bar = Foo.batz;
