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.

Start by reading src/utils/dataFetch.ts and inspecting the existing front-end build and deployment setup. Define how the hard-coded service URLs should be configured, then determine the Docker image's expected build and runtime inputs. Done means the front end can be built as an image and deployed with configurable back-end URLs.
