Creating a Server Action for Password Reset

I'll create a server action that verifies an SMS code and resets a user's password using Supabase. This will be similar to your existing server actions but focused on the password reset functionality 12.

How to Use This Password Reset Flow

1. Server Action: I've created a server action called resetPassword that handles the verification of SMS codes and password reset 2. This follows Next.js best practices for server actions.

2. Form Component: The ResetPasswordForm component provides a user interface for collecting:

   • Phone number
   • SMS verification code
   • New password
   • Password confirmation

3. Validation: The server action uses Zod for validation, ensuring that:

   • Phone number is provided
   • SMS code is provided
   • Password meets minimum length requirements (6 characters) 1
4. Integration with Supabase: The server action calls your existing Supabase RPC function http__reset_password_by_phone_number to verify the SMS code and reset the password 1.

5. Error Handling: The implementation includes comprehensive error handling for various scenarios:

   • Invalid input validation
   • Expired SMS codes (status 419)
   • Invalid SMS codes (status 404)
   • Other server errors
6. Success Flow: Upon successful password reset, the user receives a confirmation message and is redirected to the login page.

To implement this in your application, you'll need to:

1. Add these files to your project
2. Ensure your Supabase client is properly configured
3. Link to this reset password page from your login or forgot password page

This implementation follows the same pattern as your existing authentication server actions while focusing specifically on the password reset functionality.

Please make sure to add the following environment variables to your project:

Creating a Server Action for Password Reset Without RPC

I'll create a server action that handles the SMS verification and password reset logic directly without using Supabase RPC functions.

How This Password Reset Server Action Works

I've implemented a server action that handles the entire password reset process directly without relying on RPC functions. Here's how it works:

1. Server Action Implementation

The resetPassword server action now handles all the logic that was previously in the RPC function:

1. Input Validation: Uses Zod to validate the phone number, SMS code, and password
2. User Lookup: Finds the user by phone number in the database
3. SMS Code Verification: Checks if the provided code exists and matches the user's phone number
4. Expiration Check: Verifies that the SMS code hasn't expired (15-minute window)
5. Password Hashing: Uses bcrypt to securely hash the new password
6. Database Update: Updates the user's password in the database
7. Cleanup: Removes the used verification code from the database

2. Security Considerations

This implementation includes several security best practices:

• Password hashing with bcrypt (same as your registration flow)
• Verification code expiration checks
• One-time use of verification codes (deleted after use)
• Input validation to prevent malformed data

3. Error Handling

The server action handles various error scenarios:

• User not found
• Invalid SMS code
• Expired SMS code
• Database errors during password update
• General exceptions

4. Client Integration

The client-side form component remains largely the same, providing:

• Form fields for phone, code, and password
• Client-side validation for password confirmation
• Error and success state handling
• Redirection after successful password reset

Database Schema Assumptions

This implementation assumes your database has:

1. A users table with:

   • id field
   • phone field
   • password field (for storing hashed passwords)

2. A verification_codes table with:

   • id field
   • phone field (to associate codes with phone numbers)
   • code field (the actual verification code)
   • created_at field (timestamp for expiration checking)

If your database schema differs, you'll need to adjust the queries accordingly.

To implement this in your application, add these files to your project and ensure your Supabase client and database connections are properly configured.
