• Deploy server to Heroku

Open the config/config.json file for Sequelize. Rename the file to config.js. And refactor it to a module exports like below:

require('dotenv').config()
module.exports = {
  development: {
    database: '<Your Dev Database>',
    dialect: 'postgres'
  },
  test: {
    database: '<Your Database Test Name>',
    dialect: 'postgres'
  },
  production: {
    use_env_variable: 'DATABASE_URL',
    dialect: 'postgres',
    dialectOptions: {
      ssl: {
        rejectUnauthorized: false,
        require: true
      }
    }
  }
}

In models/index.js, we need to fix the require for the config. Change the config require statement to the one below:

const config = require(__dirname + '/../config/config.js')[env]

In your project directory, run:

heroku create <name of backend>

Once your app is created, we need to add postgres as an addon:

heroku addons:create heroku-postgresql:hobby-dev

Next we'll add any environment variables for your project (from your backend .env file):

heroku config:set VARIABLE_NAME=<variable>

In your package.json, add a new script in your scripts section:

    "build": "npm install && npx sequelize-cli db:migrate"

Make sure you have a start and dev script:

{
  "dev": "nodemon <entry>.js",
  "start": "node <entry>.js"
}

Publish a build by adding and committing your changes and running git push heroku main.

You can run heroku logs --tail to monitor what's happening with your server.

If you have seeds that you want to run, you can ssh into your Heroku server with heroku run bash and then running npx sequelize-cli db:seed:all.
