Author: login: amazon-q-developer[bot]
Created: 2025-05-22T05:50:01Z | Merged: 2025-05-22T06:32:43Z

This PR implements a major database infrastructure reorganization, primarily focused on centralizing and standardizing Prisma configuration and usage across the application. The key changes include:

1. Centralizes Prisma schema into a single location to serve as the source of truth
2. Restructures the database library (@a1c/db) to provide a consistent interface for database access
3. Updates path configurations and dependencies to support the new database structure
4. Adds comprehensive documentation and examples for database usage
5. Implements better testing infrastructure for database operations
6. Deprecates legacy data access patterns in favor of a standardized approach

This change aims to improve maintainability, reduce confusion around database access patterns, and prevent connection pool issues by ensuring consistent Prisma client usage throughout the application.

+# Prisma Configuration Setup
+
+This document outlines the changes made to simplify and centralize the Prisma configuration in the A1C Estimator project.
+
+## Changes Made
+
+### 1. Centralized Prisma Schema
+
+The Prisma schema has been centralized to a single location:
+
+```
+/libs/db/prisma/schema.prisma
+```
+
+This is now the single source of truth for the database schema. All duplicate schema files have been removed to avoid confusion and inconsistency.
+
+### 2. Consistent Prisma Client Generation
+
+The Prisma client is now generated to a consistent location:
+
+```
+/libs/db/generated/client/
+```
+
+This makes it easier to import the client and ensures that all parts of the application use the same client.
+
+### 3. Updated Project Configuration
+
+The `project.json` file has been updated to use consistent paths for all Prisma commands:
+
+- All commands now reference the central schema location
+- The command names have been standardized for clarity
+
+### 4. Standardized Prisma Client Usage
+
+A singleton Prisma client is now exported from the db library:
+
+```typescript
+import { prisma } from '@a1c/db';
+```
+
+This ensures that all parts of the application use the same Prisma client instance, which is more efficient and prevents connection pool exhaustion.
+
+### 5. Fixed Path Mappings
+
+The `tsconfig.base.json` path mapping for `@a1c/db` now correctly points to an existing file:
+
+```json
+"@a1c/db": ["libs/db/index.ts"]
+```
+
+### 6. Deprecated Legacy Data Access
+
+The `dataAccess()` function in `libs/data-access/src/lib/data-access.ts` has been deprecated in favor of directly importing the Prisma client from `@a1c/db`.
+
+### 7. Added Documentation and Examples
+
+- Added comprehensive documentation in `libs/db/README.md`
+- Added usage examples in `libs/db/examples/`
+- Added tests for the Prisma client
+
+## How to Use the New Setup
+
+### Importing the Prisma Client
+
+```typescript
+import { prisma } from '@a1c/db';
+
+// Use it in your code
+const users = await prisma.user.findMany();
+```
+
+### Running Prisma Commands
+
+```bash
+# Generate Prisma client
+nx run db:generate-client
+
+# Create and apply migrations
+nx run db:migrate -- --name <migration-name>
+
+# Reset database
+nx run db:migrate-reset
+
+# Open Prisma Studio
+nx run db:prisma -- studio
+```
+
+## Benefits of the New Setup
+
+1. **Simplicity**: Single source of truth for the schema and client
+2. **Consistency**: All commands and imports use the same paths
+3. **Efficiency**: Singleton Prisma client prevents connection pool exhaustion
+4. **Maintainability**: Clear documentation and examples make it easier to work with the database
+5. **Testability**: Added tests for the Prisma client
+
+## Next Steps
+
+1. Run database migrations to ensure the schema is up to date
+2. Update any remaining code that imports Prisma directly to use the centralized client
+3. Add more comprehensive tests for database operations
+4. Consider adding a seeding script for development data

+# Pipeline Fix Required
+
+The build is failing due to inconsistencies between package.json and package-lock.json. Here are the specific issues:
+
+1. Package version mismatches:
+   - @adobe/css-tools: lock shows 4.3.3, requires 4.4.3
+   - dom-accessibility-api: lock shows 0.5.16, requires 0.6.3
+   - chalk: multiple versions required, but missing from lock file
+   
+2. Missing packages in lock file:
+   - @testing-library/jest-dom@6.6.3
+   - css.escape@1.5.1
+   - min-indent@1.0.1
+   - redent@3.0.0
+   - strip-indent@3.0.0
+   - chalk@4.1.2 (multiple instances)
+   - ansi-styles@4.3.0
+   - supports-color@7.2.0
+
+## Fix Required
+
+To resolve this, you need to:
+
+1. Delete the existing package-lock.json file
+2. Run `npm install` to regenerate a clean package-lock.json with the correct versions
+3. Commit the new package-lock.json file
+
+Command sequence:
+```bash
+rm package-lock.json
+npm install
+git add package-lock.json
+git commit -m "chore: regenerate package-lock.json with correct versions"
+```
+
+This will ensure that all package versions in package-lock.json match what's specified in package.json.

-# db
+# Database Library (@a1c/db)
 
-This library was generated with [Nx](https://nx.dev).
+This library provides database access for the A1C Estimator application using Prisma ORM.
 
-## Building
+## Setup
 
-Run `nx build db` to build the library.
+The database setup has been simplified to use a centralized Prisma schema and consistent configuration.
+
+### Quick Setup
+
+A setup script is provided to quickly set up the Prisma environment:
+
+```bash
+# Make the script executable
+chmod +x libs/db/scripts/setup-prisma.sh
+
+# Run the setup script
+./libs/db/scripts/setup-prisma.sh
+```
+
+This script will:
+1. Create the necessary directories
+2. Generate the Prisma client
+3. Verify that the setup was successful
+
+### Directory Structure
+
+```
+libs/db/
+├── generated/         # Generated Prisma client files
+├── prisma/            # Prisma schema and migrations
+│   ├── schema.prisma  # The centralized Prisma schema
+│   └── migrations/    # Database migrations
+├── src/               # Source code
+│   ├── lib/           # Library code
+│   │   └── prisma-client.ts  # Prisma client singleton
+│   └── index.ts       # Main exports
+├── examples/          # Usage examples
+└── index.ts           # Re-export from src/
+```
+
+### Prisma Schema
+
+The Prisma schema is located at `libs/db/prisma/schema.prisma`. This is the single source of truth for your database schema.
+
+### Prisma Client
+
+The Prisma client is generated to `libs/db/generated/client/` and exported as a singleton from `libs/db/src/lib/prisma-client.ts`.
+
+## Usage
+
+### Importing the Prisma Client
+
+```typescript
+// Import the Prisma client singleton
+import { prisma } from '@a1c/db';
+
+// Use it in your code
+const users = await prisma.user.findMany();
+```
+
+### Common Operations
+
+See the examples directory for common usage patterns:
+
+- Basic CRUD operations
+- Transactions
+- Relations
+
+## Commands
+
+The following commands are available for working with the database:
+
+### Generate Prisma Client
+
+```bash
+nx run db:generate-client
+```
+
+This command generates the Prisma client based on your schema.
+
+### Run Migrations
+
+```bash
+nx run db:migrate -- --name <migration-name>
+```
+
+This command creates a new migration and applies it to your database.
+
+### Reset Database
+
+```bash
+nx run db:migrate-reset
+```
+
+This command resets your database and applies all migrations from scratch.
+
+### Seed Database
+
+```bash
+nx run db:seed
+```
+
+This command seeds your database with initial data.
+
+### Prisma Studio
+
+```bash
+nx run db:prisma -- studio
+```
+
+This command opens Prisma Studio, a visual editor for your database.
+
+## Environment Variables
+
+The following environment variables are required:
+
+- `DATABASE_URL`: The connection string for your PostgreSQL database
+
+Example:
+```
+DATABASE_URL="postgresql://username:password@localhost:5432/a1c?schema=public"
+```
+
+## Troubleshooting
+
+### Client Generation Issues
+
+If you encounter issues with the Prisma client generation:
+
+1. Delete the generated client directory: `rm -rf libs/db/generated/client`
+2. Regenerate the client: `nx run db:generate-client`
+
+### Database Connection Issues
+
+If you encounter database connection issues:
+
+1. Verify your DATABASE_URL environment variable
+2. Ensure your database server is running
+3. Check network connectivity to the database server
+
+## Best Practices
+
+1. Always use the exported prisma singleton from `@a1c/db` rather than creating new instances
+2. Use transactions for operations that require multiple database changes
+3. Add new models to the centralized schema.prisma file
+4. Run migrations in development to keep your local database in sync
+5. Document complex database queries in comments

body: The fix addresses the issue of potentially exposing sensitive information in error messages. The error handling in the catch block has been modified to log a generic error message without including the specific error details. Additionally, a new generic error is thrown instead of re-throwing the original error, which helps prevent leaking sensitive information to the client.
```suggestion
console.log('Transaction completed successfully:', result);
    return result;
  } catch (error) {
    console.error('Transaction failed');
    throw new Error('An error occurred while processing your request');
