三行代码高搞定nestjs静态图片映射方案

方案一 @nestjs/serve-static 库映射

上代码

npm i @nestjs/serve-static

import { ServeStaticModule } from '@nestjs/serve-static';
import { join } from 'path';
const staticPath = join(__dirname, '..', '/public/');


@Module({
  imports: [
  ServeStaticModule.forRoot(
      {
        rootPath: staticPath,
      }
    ),
    ...
  ],
  controllers: [AppController, EmailController],
  providers: [AppService, EmailService]
})

验证效果

访问地址你的host+路径
实例

访问地址

方案二 @nestjs/platform-express 映射（nest 自带不用安装）

直接上代码

...
import { NestExpressApplication } from '@nestjs/platform-express';
import { join } from 'path';
const staticPath = join(__dirname, '..', '/public');

async function bootstrap() {
  const app = await NestFactory.create<NestExpressApplication>(AppModule, {
    logger: ['verbose']
  });
  app.useStaticAssets(staticPath)
  ...
  await app.listen(3000);
}
bootstrap();

验证访问，同方案一
