Create homepage, recipes, saved post

[Silviclaudia]

• Create the tsx files or front end design following next.js inside app folder where homepage still part of app root while the rest must have its own app/login/page.tsx.
• Use @ and api fetch where it uses request like POST or GET to verify later.
• Understanding tsx further, whenever needed user input create that into state variables; useState("")->empty string so later JSON can pack it.
• Every variable inside request body (JSON), it will automatically be string, ex: username, password.
