How do I use Sequelize to connect to Heroku Postgres?


I'm seeing errors when attempting to use Sequelize in my node app.


This is the required configuration:

const Sequelize = require('sequelize');
sequelize = new Sequelize(process.env.DATABASE_URL, {
    dialectOptions: {
      ssl: {
        require: true,
        rejectUnauthorized: false

  .then(() => {
    console.log('Connection has been established successfully.');
  .catch(err => {
    console.error('Unable to connect to the database:', err);
