I'm having trouble importing a file in the database/index.js folder

Question

The problem is on line 2, import './database/index.js'.

Server.js

import './database/index.js'

And this is the index.js file, which is being imported into server.js.

import Sequelize from "sequelize";
import config from '../config/database';
import Model from '../models'
const models = [];
class Database {
    constructor() {
        this.connection = new Sequelize(config);
        this.init() this.associate()
    }
    init() {
        models.forEach((model) => model.init(this.connection))
    }
    associate() {
        models.forEach((model) => {
            if (model.associate) {
                model.associate(this.connection.models);
            }
        })
    }
}
export default new Database();

Package.json

"type": "module",

My console:

   [nodemon] starting `node ./src/server.js`
        node:internal/errors:491
            ErrorCaptureStackTrace(err);
            ^

        Error [ERR_MODULE_NOT_FOUND]: Cannot find module 'D:\Nebula\Templates\Sistema Admin\src\config\database' imported from D:\Nebula\Templates\Sistema Admin\src\database\index.js

        code: 'ERR_MODULE_NOT_FOUND'
        }

        Node.js v18.13.0

I'm try alterate a type in package.json, but continue error I believe that the problem is in the way that index.js is being exported, but I don't know another way to do that... I thought the error was due to not having the .js extension at the end of the import, but I changed it and the same thing continued.

shouldn't it be `import DB from './database/index.js'` – Dean Van Greunen Jun 11 '23 at 13:55 — Dean Van Greunen, Jun 11 '23 at 13:55
cause you need to export a reference – Dean Van Greunen Jun 11 '23 at 13:56 — Dean Van Greunen, Jun 11 '23 at 13:56

that's the wrong syntax. Try:

import * from './database/index.js';

or (more DX approach)

import { Database } from './database/index.js';

The error continues, I believe it's the way index.js is done, don't you think? – Mateus Full Stack Dev Jun 12 '23 at 22:57
