This app takes a "configuration through JS" approach which can give more flexibility compared to regular JSON files. Config files are stored under config with "{environment}.js" naming pattern.

You can use ENV environment variable to specify the desired environment. Default one is "development".

Create an empty postgresql database and make sure its name and associated user credentials are matching to corresponding values in the config file.

Run npm run db_migrate to populate database structure.

Optionally you can specify an environment: npm run db_migrate -- --env production

Note: To roll back the last migration you can use npm run db_rollback

Note: For more complex cases you may need to install knex CLI globally (along with postgresql driver) or directly invoke local version like this: ./node_modules/.bin/knex ...

Note: Make sure you created a development database.

Run npm test

Note: Make sure you created a production database.

Run npm start
