Implement Strezless music platform with industry code validation and secure Next.js 15

[Copilot]

Full-stack indie artist platform for managing music catalogs, professional industry codes, and royalty tracking.

Core Implementation

Database Schema (Prisma)

• 8 models: User, Artist, Song, Album, Release, Collaboration, Revenue, Analytics
• Industry identifiers: IPI, ISNI, ISRC, ISWC, UPC, EIN with relational integrity

Custom Validation Algorithms
Implemented mathematical validation for music industry codes:

// IPI: 9-digit modulo 10 check digit validation
const validateIpiStructure = (value: string): boolean => {
  const digits = cleanedValue.split('').map(Number);
  const checkDigit = digits[8];
  const sumOfDigits = digits.slice(0, 8).reduce((sum, digit, index) => {
    return sum + digit * (9 - index);
  }, 0);
  const calculatedCheck = (10 - (sumOfDigits % 10)) % 10;
  return calculatedCheck === checkDigit;
};

// ISNI: 16-character checksum validation
// ISRC: Format validation (CC-XXX-YY-NNNNN)
// UPC: 12-digit check digit calculation

API Routes

• /api/artists - CRUD with pagination, search, duplicate code detection
• /api/artists/[id] - Individual management with stats aggregation
• /api/songs - Catalog management with ISRC validation

Frontend

• Artist profile form with React Hook Form + Zod
• Collapsible sections for optional professional data
• Custom Tailwind theme (purple/pink/orange gradients)

Security

Next.js Upgrade: 14.2.35 → 15.5.12

• Resolved 9 DoS vulnerabilities in React Server Components
• Updated API route handlers for async params:

// Before (Next.js 14)
export async function GET(
  request: NextRequest,
  { params }: { params: { id: string } }
) {
  const artistId = params.id;
}

// After (Next.js 15)
export async function GET(
  request: NextRequest,
  { params }: { params: Promise<{ id: string }> }
) {
  const { id: artistId } = await params;
}

Configuration

• TypeScript strict mode
• Tailwind CSS 3.4 with custom design system
• ESLint with Next.js ruleset
• Environment templates for database and auth

npm audit: 0 vulnerabilities

Firewall rules blocked me from connecting to one or more addresses (expand for details)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)

Original prompt

The goal is to implement the Strezless platform based on the details outlined in pull request #12 in the "Sin-Estres-dev/Strezless" repository. The platform is designed to support indie artists with a production-ready Next.js full-stack application and includes features for artist profile management, music cataloging, API routes, and modern UI components.

Please ensure the following tasks are completed:

---

1. Project Setup & Configuration

• Initialize Next.js 14+ with TypeScript.
• Configure Tailwind CSS.
• Set up Prisma ORM for database management.
• Create and configure the package.json file to include all required dependencies.
• Create and configure TypeScript settings (tsconfig.json) and Tailwind configuration files (tailwind.config.ts, postcss.config.js).
• Define an .env.local template for managing environment variables.

2. Database Schema

• Design a comprehensive Prisma schema with models for:
  • User (authentication and session management).
  • Artist (includes professional identifiers like IPI, ISNI, etc.).
  • Songs (metadata with ISRC, UPC codes, etc.).
  • Albums and releases.
  • Collaborations.
  • Monetization and analytics.

3. API Routes

• Implement RESTful API routes to handle operations such as:
  • POST/GET /api/artists: Create and fetch artist profiles.
  • GET/PUT /api/artists/[id]: Retrieve and update artist profiles.
  • POST/GET /api/songs: Create and manage songs.
• Include input validation using Zod.

4. Frontend Components

• Develop the ArtistProfileForm.tsx React component with proper form validation and responsive design.
• Implement detailed error handling for user interactions.

5. Pages & UI

• Create main landing page setup (page.tsx).
  • Showcase featured artists with an artist discovery dashboard.
• Develop reusable UI components and add responsive navigation features.

6. Development Utilities

• Create a Prisma client singleton utility (src/lib/prisma.ts) for database access patterns.

7. Documentation & Testing

• Update the .gitignore file for production safety.
• Add .env.local configuration examples.
• Validate all routes.
• Write E2E or unit tests, ensuring code quality

Take time to internally lint or code endpoints align coding current Nomral to production-output integration Strezless-framework.
