How to connect to SQL Server with windows authentication from Node.JS using mssql module

I have been struggling too for some time about how to use mssql + Windows Auth, here is how i got it to work on my project.

As pointed out in the mssql documentation, you need msnodesqlv8 installed too.

npm install msnodesqlv8

Now, following on Aaron Ballard's answer, you use it like this:

const sql = require('mssql/msnodesqlv8')

const pool = new sql.ConnectionPool({
  database: 'database',
  server: 'server',
  driver: 'msnodesqlv8',
  options: {
    trustedConnection: true
  }
})

pool.connect().then(() => {
  //simple query
  pool.request().query('select 1 as number', (err, result) => {
        console.dir(result)
    })
})

As a note, i tried to add this as a comment on Aaron's answer, as mine is just a complement/update to his, but i don't have enough reputation to do so.
