javascript - How to introduce multiple exports when there are multiple exports in js?

Question

// mutation-types.js
export const SOME_MUTATION = 'SOME_MUTATION'
export const SOME_MUTATION_1 = 'SOME_MUTATION_1'

I want to import mutation-types.js, how to write it better?

Answer 1

import * as types from 'mutation-types.js'
// types.SOME_MUTATION types.SOME_MUTATION_1

Answer 2

import * as TYPES from './mutation-types';

console.log(TYPES.SOME_MUTATION)

Answer 3

如果你想全部导入：
import * as mutationTypes from './mutation-types';
如果你只是想导入 mutation-types里的几个可以:

import {SOME_MUTATION,SOME_MUTATION_1} from './mutation-types';

Answer 4

You can put SOME_MUTATION and SOME_MUTATION_1 in an export object:

let obj = {
    SOME_MUTATION : 'SOME_MUTATION',
    SOME_MUTATION_1 : 'SOME_MUTATION_1'
}

export obj
