sqlite3_1.default.database is not a constructor - electron

Question

I installed in my Electron-React-Typescript-Webpack app sqlite3 via yarn: yarn add sqlite3#latest
and rebuilt everything with yarn electron-rebuild -f -w sqlite3
In webpack.config.js I've put:
const webpack = require('webpack');
externals: [
{
'sqlite3': sqlite3,
}
],
If in main.ts I put:
import sqlite3 from 'sqlite3';
let db = new sqlite3.Database(
path.join(app.getPath('userData'),'/infopiecesleveldb'),
(err) => {
if (err) {
return console.error(err.message);
}
console.log('Connected to the in-memory SQlite database.');
});
I get this error: sqlite3_1.default.database is not a constructor
(node:2679) UnhandledPromiseRejectionWarning: TypeError: sqlite3_1.default.database is not

Any ideas about how to solve it?

With
import sqlite3 from 'sqlite3';
//let db = new sqlite3.Database(':memory:', (err) => {
let db = new sqlite3.Database(
path.join(app.getPath('userData'),'/infopiecessql3db'),
(err) => {
if (err) {
return console.error(err.message);
}
console.log('Connected to the in-memory SQlite database.');
});
db.close();
now I get this message Connected to the in-memory SQlite database
