Modules
​AirBNB JavaScript Style Guide: Modules​
10.1 Always use modules (import/export) over a non-standard module system.
10.2 Do not use wildcard imports.
10.6 In modules with a single export, prefer default export over named export.
Interpretation: multiple exports allowed
Confusing as hell
ESM vs CommonJS vs ES6
If using export default use import var from module:
1
export const foo = 42
2
export default 21;
Copied!
If you want the 21, use import bar from './input';
1
import barImport from './input';
2
console.log(barImport); // 21
3
​
4
const barRequire = require('./input');
5
console.log(barRequire);
6
/*
7
{
8
    foo: 42,
9
    default: 21,
10
}
11
*/
Copied!
Notes
1
export const types = () => {}
Copied!
is different from
1
export function types() { }
Copied!
