fix(prisma): Too many idle db connections #646

Closed sashko9807 closed 2 months ago

When importing a service through the provider interface of the module, NestJS creates new instance each time that provider service is referenced.

For example if we have 20 modules which have PrismaService as a provider, a 20 instances of PrismaService will be created, which could result in many idle db connections.

To fix this:

Added PrismaModule which would export PrismaService
Replaced providers: [PrismaService] with imports: [PrismaModule] which ensures only a single instance of PrismaService is created.
