To run your server you have to create your .env file and have the following variables inside of it and set it to the value of your choice.

PORT=

DB_NAME=

DB_USER=

DB_PASSWORD=

DB_HOST=

ACCESS_TOKEN_SECRET=

After this, use the "npm run dev" to run your server. This would show you confirmation messages on the performance of the app. You would also need a pgadmin GUI that comes with Postgresql to create a database.

You can also test the endpoints using postman

Finally you can run a end-to-end tests using npm test
