const firebird = require('node-firebird')
const options = {
    host: '127.0.0.1',
    port: 3050,
    database: 'C:/Users/JEFTER/Documents/firebird-node-dev/data/TEST.FDB',

    lowercase_keys: false, // set to true to lowercase keys
    role: null,            // default
    pageSize: 4096         // default when creating database
}

firebird.attach(options, (err, db) => {

    if (err)
        console.log(err)

    // db = DATABASE
    db.query('SELECT * FROM TEST', (err, result) => {
        // IMPORTANT: close the connection
        db.detach()
    })
})

My Firebase: version 2.5.x, OS: Windows 10

The TEST.fbd database has a table TEST with 2 users with id and name.
