Redis storage does is not working - no errors about nestjs-throttler-storage-redis

[dmolim]

Hi @twigs67, I've just installed and configured the module and it successfully works with the following packages:

"ioredis": "^5.3.1",
"nestjs-throttler-storage-redis": "^0.3.0",
"redis": "3",
"@types/ioredis": "^5.0.0",

Here's my storage configuration:

storage: new ThrottlerStorageRedisService(
  new Redis({
    host: configService.get<string>('REDIS_HOST'),
    port: +configService.get<string>('REDIS_PORT'),
    password: configService.get<string>('REDIS_PASSWORD'),
    db: +configService.get<string>('REDIS_THROTTLER_DB'),
  }),
),

@twigs67 You can check if rate limiter is working by using redis-cli monitor in your terminal after you started redis and then you should see an EVAL, INCR, PTTL and PEXIRE being executed:

Shell 1: redis-server start redis server
Shell 2: yarn start:dev start your project
Shell 3: redis-cli monitor start redis monitoring

Then in shell 4 you can run curl localhost:3000 (assuming your application runs on this address) and then in shell 3 you will see:

1678096891.755335 [0 127.0.0.1:55191] "EVAL" "local totalHits = redis.call(\"INCR\", KEYS[1])\nlocal timeToExpire = redis.call(\"PTTL\", KEYS[1])\nif timeToExpire <= 0\nthen\nredis.call(\"PEXPIRE\", KEYS[1], tonumber(ARGV[1]))\ntimeToExpire = tonumber(ARGV[1])\nend\nreturn { totalHits, timeToExpire }" "1" "8b40547db3793cee1110528738884f6a" "10000"

If you see something to this output, you know the throttler works.
