Hello anyone who is seeing this,
My Backend will be running on this server http://localhost:3333/transactions and my Frontend will be running on http://localhost:3000/.
Backend GitHub Link https://github.com/ajvee/budget-app-backend
Here is a link to my trello board https://trello.com/b/pbqFoQjV/fullstack-budget-app
All the added and deleted transactions from my frontend will update my backend.
