如何在单独的类中使用NESTJS模块

npm install -g @nestjs/cli

nest g module moduleName

nest g class className

import { Module } from '@nestjs/common';

@Module({})
export class ClassNameModule {}

import { Module } from '@nestjs/common';
import { DatabaseModule } from 'database.module';

@Module({
  imports: [DatabaseModule],
})
export class ClassNameModule {}

import { Module } from '@nestjs/common';
import { DatabaseModule } from 'database.module';
import { ClassName } from 'class-name';

@Module({
  imports: [DatabaseModule],
  exports: [ClassName],
})
export class ClassNameModule {}

import { Module } from '@nestjs/common';
import { ClassNameModule } from 'class-name.module';
import { ClassName } from 'class-name';

@Module({
  imports: [ClassNameModule],
})
export class AnotherModule {
  constructor(private readonly className: ClassName) {}
}
