dockerize the front-end as well?

The web page looks really nice! I am wondering if you could also make a docker image for the front-end? In this way, we can easily deploy the back-end and front-end to somewhere.

Also, I find there are some hard-coded URLs (such as localhost:8080... in src/utils/dataFetch.ts) in the front-end. That would be nice to have a configuration file for them if we want to deploy it.
