Class RedisCache

Represents a specific implementation of a caching mechanism using Redis as the underlying storage system. It extends the BaseCache class and overrides its methods to provide the Redis-specific logic.

Example

const model = new ChatOpenAI({ cache: new RedisCache(new Redis(), { ttl: 60 }) });

// Invoke the model to perform an action
const response = await model.invoke("Do something random!");
console.log(response);
