In an "old way" of managing modules in Node.JS (CommonJS modules) you can do something like this:
Example of Express.js route: app.use('/user', require("./user"));
How to do this when I am using ES6 Modules (import, export) and transcribing by Node.JS server by babel?
I can't just do: app.use('/user', import {user} from './user');
There is a way to do dynamic inline imports in node, detailed here: https://javascript.info/modules-dynamic-imports
This code has worked for me:
let {default: foo} = await import('./foo.js'); Here is a working example of a function I wrote as part of a db migration tool in node.
const getMigrations = async (path) => { const migrateDir = await fs.readdirSync(path); const migrations = await Promise.all(migrateDir.map(async (filename) => { let {default: migration} = await import(`${path}/${filename}`); return migration; })); migrations.sort((a, b) => { return a.seq - b.seq; }); return migrations; }; Where an example migration is like:
export default { seq: 1.1, label: 'create user table', sql: ` DROP TABLE IF EXISTS user; CREATE TABLE user ( ... ); ` }; I am using node v12.18.4 with "type": "module" in my package.json. When I run the script, I get a warning that the ESM module loader is experimental, but it works. However, there is a note on the page linked to above that says:
Dynamic imports work in regular scripts, they don’t require script type="module".
I hope this helps. I believe you should be able to apply this to your problem.
Try separating it out into multiple expressions - import (as well as export) are not available at the same lexical level as you are trying to use it the example:
import { user } from './user' ... app.use('/user', user) 
You can achieve what you want using the following syntax:
app.use('/user', (await import('./user')).user) 
app.use("/user", user);app.use('/user', user);importandexporthave to be done at the outer lexical level, so you really cannot do what you're asking.
