Answer 1

First of all, have you installed the type module for the redis module? I highly recommend doing that as it helps TypeScript compiler and potentially your IDE to know what commands and interfaces are available in the redis module. To do so:

npm i --save-dev @types/redis

Second, try adding the .on('error', console.error) to see if your client is emitting any meaningful connection errors. There could be a problem with you client credentials, which fails the connections.

Lastly, you can completely skip the .on('ready', ...) event handler as it's not necessary. The redis module queues all the commands sent before the connection is established, and will automatically send them once it's successfully connected. You can just start testing the client with simple set and get commands.
