3. Update your .env.local file with the credentials
4. Test the integration using the Sandbox environment

Database Schema

The project uses Prisma with PostgreSQL. Here’s the schema setup:

// prisma/schema.prisma

generator client {
  provider = "prisma-client-js"
}

datasource db {
  provider = "postgresql"
  url      = env("DATABASE_URL")
}

model User {
  id            String         @id @default(cuid())
  name          String
  email         String        @unique
  password      String
  balance       Float         @default(0)
  createdAt     DateTime      @default(now())
  updatedAt     DateTime      @updatedAt
  loans         Loan[]        @relation("UserLoans")
  investments   Loan[]        @relation("UserInvestments")
  savingsGoals  SavingsGoal[]
  transactions  Transaction[]
}

model Loan {
  id            String      @id @default(cuid())
  amount        Float
  interestRate  Float
  duration      Int         // Duration in months
  status        String      // Active, Completed, Defaulted
  borrowerId    String
  lenderId      String?
  createdAt     DateTime    @default(now())
  updatedAt     DateTime    @updatedAt
  borrower      User        @relation("UserLoans", fields: [borrowerId], references: [id])
  lender        User?       @relation("UserInvestments", fields: [lenderId], references: [id])
}

model SavingsGoal {
  id            String      @id @default(cuid())
  title         String
  targetAmount  Float
  currentAmount Float       @default(0)
  deadline      DateTime
  userId        String
  createdAt     DateTime    @default(now())
  updatedAt     DateTime    @updatedAt
  user          User        @relation(fields: [userId], references: [id])
}

model Transaction {
  id            String      @id @default(cuid())
  type          String      // Deposit, Withdrawal, Transfer
  amount        Float
  description   String?
  userId        String
  createdAt     DateTime    @default(now())
  user          User        @relation(fields: [userId], references: [id])
}

Files to Remove

You can safely remove the following files/directories as they are specific to the StackBlitz environment:

• .bolt/ directory and all its contents
• Any .stackblitz directories or files

Additional Setup Steps

1. Install VS Code Extensions:
   • Prisma (for database schema)
   • ESLint
   • Prettier
   • Tailwind CSS IntelliSense
2. Install additional dependencies:

   npm install @prisma/client @auth/prisma-adapter next-auth axios
   

3. Set up ESLint and Prettier:

   npm install -D prettier eslint-config-prettier
   

Development Workflow

1. Start the development server:

   npm run dev
   

2. Access the application at http://localhost:3000

3. For database changes:

   npx prisma generate  # After schema changes
   npx prisma db push   # Push changes to database
   

4. For M-Pesa testing:
   • Use the Sandbox environment first
   • Test all transactions with test credentials
   • Move to production only after thorough testing

Deployment

1. Build the application:

   npm run build
   

2. Test the production build:

   npm start
   

3. Deploy to your preferred hosting platform (Vercel recommended for Next.js applications)
