node db config

`const { Sequelize } = require("sequelize"); const { PGHOST, PGUSER, PGDATABASE, PGPASSWORD } = require("../../env");

const sequelize = new Sequelize(PGDATABASE, PGUSER, PGPASSWORD, { host: PGHOST, dialect: "postgres", operatorsAliases: 0, logging: false, pool: { max: 5, min: 0, acquire: 30000, idle: 10000, } })

const connectionTest = async () => { try { await sequelize.authenticate(); console.log('Connection has been established successfully.'); } catch (error) { console.error('Unable to connect to the database:', error); } } connectionTest()`
