The code for connecting to redis seems to work fine. You can check if redis is running on your system:

sudo service redis status

If the status is not active try to restart the service. You can refer to this code for creating a better wrapper for redis: https://github.com/kumaranshu72/node_ts_boilerplate/blob/github/src/utils/redis.ts
