Prisma Client: Injectable Setup Outside NestJS (with/without DI)?

In NestJS, the Prisma Client can be made injectable by extending

PrismaClient

PrismaClient

and implementing lifecycle hooks like

onModuleInit

onModuleInit

to manage connections. Here's how it's typically done in NestJS:

import { Injectable, OnModuleInit, INestApplication } from '@nestjs/common';
import { PrismaClient } from '@prisma/client';

@Injectable()
export class PrismaService extends PrismaClient implements OnModuleInit {
  async onModuleInit() {
    await this.$connect();
  }
}

import { Injectable, OnModuleInit, INestApplication } from '@nestjs/common';
import { PrismaClient } from '@prisma/client';

@Injectable()
export class PrismaService extends PrismaClient implements OnModuleInit {
  async onModuleInit() {
    await this.$connect();
  }
}

1. How would a similar Prisma Client setup be implemented in a non-NestJS application (for example, an Express app) without using a dependency injection tool?
2. How would this setup change if you were to use a dependency injection tool (like Tsyringe or any other DI library) in your non-NestJS application?
