NestJS - How/Where to configure FileInterceptor with async way

As the documentation says: we can have an async configuration for the file interceptor.

I would like to use this to use my ConfigService for the upload directory (who is different by environment). But I don't know where to write this async configuration.

The documentation give us an example to set the configuration but I don't know how to integrated this to my project.

I have check the official documentation and especially the Techniques/File Upload and Overview/Middleware. I have tested some implementation but my configuration seems to be never used.

I use this method to configue Multer:

MulterModule.registerAsync({
  imports: [ConfigModule],
  useFactory: async (configService: ConfigService) => ({
    storage: diskStorage({
      destination: configService.downloadFolder,
      filename: (req, file, cb) => {
        const randomName = Array(32)
          .fill(null)
          .map(() => Math.round(Math.random() * 16).toString(16))
          .join('')
        return cb(null, `${randomName}${extname(file.originalname)}`)
      }
    })
  }),
  inject: [ConfigService]
})

Do you have any idea how to integrate this configuration?

Thank you for your help :)

As Multer Module is not a global module, so the setting in the app.module.ts not work! It should set at the module which used the file upload.

You have to import MulterModule in your AppModule to set the default configuration:

@Module({
  imports: [
    MulterModule.registerAsync(...)
  ],
})
export class AppModule{}
