PIMS-408 Establish Migration Options

[dbarkowsky]

🎯 Summary

PIMS-408

Changes

• Added commands to the package.json to access typeorm and the migration commands.
• Added a script that handles some migration command options, allowing users to specify migration names.

Note: This will create a migrations table in Postgres. This is how TypeORM knows which migrations to run.

Testing

Works best if you have an empty database (generates migration to create all tables), but could be done by just editing an entity and running the commands.

Recommend running the commands and seeing the results.

Commands Added

• npm run migration create <migrationName> - Creates a blank migration file.
• npm run migration generate <migrationName> - Generates the migration file needed to sync the database to your entity files.
• npm run migration run - Executes outstanding migrations.
• npm run migration revert - Rolls back the most recent migration.
