    username: "your-redis-username",
    password: "your-redis-password",
    database: 0,
};
await RedisBloomWrapper.init(redisCreds);

// Create a Bloom Filter
const bloomFilterKey = "my-bloom-filter";
const capacity = 100000;
const errorRate = 0.01;
await RedisBloomWrapper.createBloomFilter(bloomFilterKey, capacity, errorRate);

// Add an item to the Bloom Filter
const item = { id: "123", name: "John Doe" };
await RedisBloomWrapper.add(bloomFilterKey, item);

// Check if an item exists in the Bloom Filter
const exists = await RedisBloomWrapper.exists(bloomFilterKey, item);
console.log("Item exists in Bloom Filter:", exists.result);

// Delete the Bloom Filter
await RedisBloomWrapper.deleteBloomFilter(bloomFilterKey);
