steps

1. Implement auth module and implement register and login function
2. configure api gateway to send out the request to the user service through a transport layer
3. add redis package for transport layer and nest microservice 
4. Add transporters and export module 
5. Add injection token options
6. add npm i --save @nestjs/config for env file read
7. setup the user service client 
8. Add global pipe validation / dto

10. Install ioredis
11. Add exception filter for structuring our exceptions messages
12. Add interceptors to organize our respose as well
13. Test out the request without providing the user service to consume it 
14. Talk about how the redis server works and doesn't keep a log of the message for the service to consume once it comes up
15. Share that we can use Redis Stream that keeps a log of the message , - redis uses a fire-forget mode 
16. Set timeout to your transport and retry options
