# Usage

Basic usage:

```ts
import { ThrottlerModule, seconds } from '@nestjs/throttler';
import { ThrottlerStorageRedisService } from '@nest-lab/throttler-storage-redis';
import Redis from 'ioredis';

@Module({
  imports: [
    ThrottlerModule.forRoot({
      throttlers: [{ limit: 5, ttl: seconds(60) }],

      // Below are possible options on how to configure the storage service.

      // default config (host = localhost, port = 6379)
      storage: new ThrottlerStorageRedisService(),

      // connection url
      storage: new ThrottlerStorageRedisService('redis://'),

      // redis object
      storage: new ThrottlerStorageRedisService(new Redis()),

      // redis clusters
      storage: new ThrottlerStorageRedisService(
        new Redis.Cluster(nodes, options)
      ),
    }),
  ],
})
export class AppModule {}
```

Inject another config module and service:

```ts
import { ThrottlerModule } from '@nestjs/throttler';
import { ThrottlerStorageRedisService } from '@nest-lab/throttler-storage-redis';

@Module({
  imports: [
    ThrottlerModule.forRootAsync({
      imports: [ConfigModule],
      inject: [ConfigService],
      useFactory: (config: ConfigService) => ({
        throttlers: [
          {
            ttl: config.get('THROTTLE_TTL'),
            limit: config.get('THROTTLE_LIMIT'),
          },
        ],
        storage: new ThrottlerStorageRedisService(),
      }),
    }),
  ],
})
export class AppModule {}
```
