Using Redis with Node.js can provide efficient and scalable data storage for your applications. One common use case is retrieving all hash keys stored within a specific hash. This is useful when you need to examine or manipulate all entries of a hash.
To fetch all keys in a hash, you'll want to use the
HKEYS command. Here's an example using the
In this example, 'hashKey' is the key of the hash you want to retrieve all keys from. The callback function will be called with an error (or null) and an array of keys.
Q: Can I get all keys and values at the same time?
A: Yes. For this, you can use the
HGETALL command instead of
HKEYS. This will return an object with key-value pairs.
