如何使用@nestjs/terminus为Prisma创建自定义健康检查？

npm install @nestjs/terminus prisma

import { Controller, Get } from '@nestjs/common';
import { HealthCheck, HealthCheckService, HealthCheckResult } from '@nestjs/terminus';
import { PrismaService } from './prisma.service';

@Controller('health')
export class HealthController {
  constructor(
    private health: HealthCheckService,
    private prismaService: PrismaService,
  ) {}

  @Get()
  @HealthCheck()
  async check(): Promise<HealthCheckResult> {
    const databaseStatus = await this.prismaService.checkDatabaseConnection();

    return this.health.check([
      async () => databaseStatus,
      // Add more checks if needed
    ]);
  }
}

import { Module } from '@nestjs/common';
import { TerminusModule } from '@nestjs/terminus';
import { HealthController } from './health.controller';
import { PrismaService } from './prisma.service';

@Module({
  imports: [TerminusModule],
  controllers: [HealthController],
  providers: [PrismaService],
})
export class AppModule {}
