Error: Please install tedious package Manually

Question

I am trying to do a project in Node.js / Electron and need to get information from an SQL Server database. When I run the line below, the error appears:

const db = new Sequelize('banco', 'sa', 'xxyyuuu',{dialect:"mssql", host: "servidor"});

I already reinstalled everything in a new directory and could not find a solution.

Answer 1

Based on the link quoted in the comments, I did the following to resolve:

I created a file called db.js with the following code:

import * as tedious from 'tedious';

const Sequelize = require('sequelize');
const db = new Sequelize('banco', 'usuario', 'senha',{dialect:"mssql", dialectModule : tedious, host: "hostdb"});

export {
    db
}

What I did differently:

• import * as tedious from 'tedious';
• dialectModule : tedious
• export { db }

That solved the problem.
