Hello !
Is this need for a shopping list application still actual ?
Please check this thread for a discussion on building such apps with a low code plateform :
Such a shopping list application could include a database for product I can buy, to make it more complete.
To be discussed, I am willing to give access to my low code technology (that I am currently open sourcing) for building such an application. First step : I will create a connector between GO and SOLID
