Shutdown Hook

Handle Prisma shutdown to gracefully close your Nest application. Add the enableShutdownHooks of your Prisma Service in the main.ts file.

PrismaService

Use PrismaService when Prisma Client uses the default output location.

// src/main.ts
import { NestFactory } from '@nestjs/core';
import { AppModule } from './app.module';
import { PrismaService } from 'nestjs-prisma';

async function bootstrap() {
  const app = await NestFactory.create(AppModule);

  // enable shutdown hook
  const prismaService: PrismaService = app.get(PrismaService);
  await prismaService.enableShutdownHooks(app);

  await app.listen(3000);
}
bootstrap();

CustomPrismaService

Use CustomPrismaService when you configured a custom Prisma Client location or Prisma Client Extensions.

// src/main.ts
import { NestFactory } from '@nestjs/core';
import { AppModule } from './app.module';
import { CustomPrismaService } from 'nestjs-prisma';
import { extendedPrismaClient } from './prisma.extension';

async function bootstrap() {
  const app = await NestFactory.create(AppModule);

  const customPrismaService: CustomPrismaService<extendedPrismaClient> =
    app.get('PrismaService'); // 👈 use the same name as in app.module.ts
  await customPrismaService.enableShutdownHooks(app);

  await app.listen(3000);
}
bootstrap();

The name property for CustomPrismaService must be matching name used to register CustomPrismaModule.

// src/app.module.ts
import { Module } from '@nestjs/common';
import { CustomPrismaModule } from 'nestjs-prisma';
import { AppController } from './app.controller';
import { AppService } from './app.service';
import { extendedPrismaClient } from './prisma.extension';

@Module({
  imports: [
    CustomPrismaModule.forRootAsync({
      name: 'PrismaService', // 👈 must be the same name here
      useFactory: () => {
        return extendedPrismaClient;
      },
    }),
  ],
  controllers: [AppController],
  providers: [AppService],
})
export class AppModule {}
