sequalize migration with dotenv

Sequelize does mention this in their docs. You can run migrations command by specifying the environment.

sequelize db:migrate --env production

1. Rename config.json to config.js and call your environment variables inside.

module.exports = {
  development: {
    username: process.env.DB_USER,
    password: process.env.DB_PASSWORD,
    database: process.env.DB_NAME,
    host: process.env.DB_HOST,
    dialect: 'postgres',
    logging: false,
  },
  test: {
    username: process.env.DB_USER,
    password: process.env.DB_PASSWORD,
    database: process.env.DB_NAME,
    host: process.env.DB_HOST,
    dialect: 'postgres',
    logging: false,
  },
  production: {
    username: process.env.DB_USER,
    password: process.env.DB_PASSWORD,
    database: process.env.DB_NAME,
    host: process.env.DB_HOST,
    dialect: 'postgres',
    logging: false,
    pool: {
      max: 5,
      min: 0,
      acquire: 30000,
      idle: 10000,
    },
  },
};

2. Create a .sequelizerc file with the following:

'use strict';

require('dotenv').config();    // don't forget to require dotenv
const path = require('path');

module.exports = {
  'config': path.resolve('config', 'config.js'),
  'models-path': path.resolve('models'),
  'seeders-path': path.resolve('seeders'),
  'migrations-path': path.resolve('migrations'),
};

3. Run sequelize db:migrate
