-In this code:
-
-We're importing the Keyv library and initializing it with an SQLite database.
-
-We're creating a CacheService class with get, set, and delete methods that wrap the corresponding methods of the Keyv instance. The get method includes console logs to indicate whether the requested value was found in the cache.
-
-The set method includes an optional ttlInMilliseconds parameter, which you can use to set a time-to-live (TTL) for the cached value.
-
-Now you have a reusable CacheService that you can use to add caching to your Node.js project.
-
-Here is how you could use the CacheService:
-
-```javascript
-const CacheService = require('./cacheService');
-const cache = new CacheService();
+// Initialize Keyv with Redis as the storage backend
+const secondary = new KeyvRedis('redis://user:pass@localhost:6379');
+const cache = new Cacheable({ secondary, ttl: '4h' }); // default time to live set to 4 hours
