Description:

This PR refactors the Prisma Client initialization to use a more robust and concise singleton pattern. The changes ensure that only one instance of PrismaClient is created and reused throughout the application, which improves performance and avoids potential issues with multiple instances.

Changes:

  1. Singleton Pattern: Introduced a prismaClientSingleton function to create a single instance of PrismaClient.
  2. Global Scope Handling: Utilized globalThis to manage the global instance of PrismaClient, ensuring compatibility across different environments (Node.js, browser, etc.).
  3. Environment Check: Added a check to set the global instance only in non-production environments to avoid issues in serverless environments.

Benefits:

  • Performance Improvement: Ensures a single instance of PrismaClient is used, reducing overhead.
  • Code Cleanliness: The new implementation is more concise and easier to understand.
  • Future-Proofing: Using globalThis makes the code more robust and compatible with future JavaScript standards.

Testing:

  • Verified that the application initializes and uses a single instance of PrismaClient.
  • Ensured that the global instance is only set in development environments.

I was forced to come up with a different approach as it wasn't always working in my own monorepo. Please review the changes and provide feedback if you don't like anything. Thank you!
