How to combine the ability to use import and require?

Question

Node.js

When trying to use import, it gave an error that it is possible only in modules
Added a property to Jason
"type": "module"
Since then, it began to swear at require
How to combine them?

const express = require('express')
const app = express()
const port = 3300
import {currency} from './api/currency.js'

app.get('/', (req, res) => {
  res.send('Hello World!')
})

app.listen(port, () => {
  console.log(`Example app listening at http://localhost:${port}`)
})
