Am pbkect wrapper to make its operations error proof. Basically, any error is ignored. You can have a callback when an error happens, for registering purpose, bue during the application use, every error will be ignored and undefined will be returned instead.
How to Install
npm i get-safe-instance
How to use it
Just wrap your redis instance and use the wrapped one
const wrappedRedis = getSafeInstance(someRedisInstance, timeout, ['get', 'getBuffer'], myErrorCallback)
Now, the wrapped instance will never throw an error during get or getBuffer calls, instead, it will resolve to undefined. See that only methods that return promises can be wrapped like that, as, under the hood, we also use opossum to have a circuit breaker on the given methods, avoiding some calls if constants errors are happening. Finally, the given methods will also return undefined if they reach the specified timeout without returning anything.
