how to load config folder in nestjs-config?

Question

I use ConfigService in nestjs

my code

app.module.ts

ConfigModule.forRoot({ isGlobal: true, load: [ databaseConfig, redisConfig, appConfig, ... ], }),

too much lines in load property.

so how can load one time?

how to read folder in loader?

my folder is like this.

• config
  • database.config.ts
  • redis.config.ts
  • app.config.ts
  • ...

i can't solve this problem. i read nestjs doc but i cant find.
