JavaScript Structure Overhaul & Supabase Integration

I wrote my entire JavaScript front-end as one large file and it has become hard to maintain. I now need the codebase broken into clear, self-contained modules: Home, Market, Order, Purchase, Wallet and Profile. Each view or feature should live in its own file, exporting only what it needs so that I can edit or extend a single section without touching the rest.

At the same time I want a proper sign-up, login and password-reset flow wired to Supabase. The registration form must collect e-mail, phone number and a user-chosen username, store them in my Supabase table, and confirm that the record is created before routing the user forward. For “Forgot password”, the user should be able to request a reset code that arrives either by e-mail or by the phone number on file; entering that code should let them set a new password and regain access. in sign up i want my email to send code to their email or phone number.. though i opened temii to send sms to phone number confirmation but not working.
