节点 js SyntaxError：意外的令牌“导出”

Question

I'm having the following error in the console when I try to run my api written in node js.

Can you tell me which is the problem.

Answer 1

Importing is generally done at the top of your files and looks like this:

import User, {schema} from './model.js'

Exporting is generally done at the bottom of your files and looks like this:

module.exports = {User, schema}

Ant the specific reason why you get the error is because export is not used that way.

This directly quoted from Web Docs :

export DefaultExport from 'bar.js'; // Invalid

Answer 2

If you want to include a structure you have built, you need to use import. If you want to export a structure that you have edited, you need to use export.

Answer 3

You are using ES6 syntax.

Node.js uses common.js syntax

You can use module.export syntax or you can use babel npm package for translate ES6 syntax to common.js syntax
