/**
 *
 * Can run standalone as:
 *   ts-node test/gen-server/seed.ts serve
 * By default, uses a landing.db database in current directory.
 * Can prefix with database overrides, e.g.
 *   TYPEORM_DATABASE=:memory:
 *   TYPEORM_DATABASE=/tmp/test.db
 * To connect to a postgres database, change ormconfig.env, or add a bunch of variables:
 *   export TYPEORM_CONNECTION=postgres
 *   export TYPEORM_HOST=localhost
 *   export TYPEORM_DATABASE=landing
 *   export TYPEORM_USERNAME=development
 *   export TYPEORM_PASSWORD=*****
 *
 * To just set up the database (migrate and add seed data), and then stop immediately, do:
 *   ts-node test/gen-server/seed.ts init
 * To apply all migrations to the db, do:
 *   ts-node test/gen-server/seed.ts migrate
 * To revert the last migration:
 *   ts-node test/gen-server/seed.ts revert
 *
