However, by the very nature of my work, the interfaces to most of my applications is limited to the CLI. The farthest I've gotten to front-end is Python plotly and bokeh dashboards. I'm looking to change that.

I would love to build tools like https://github.com/mobz/elasticsearch-head or https://github.com/mwielgoszewski/doorman. I've built custom tools to the likes of Airflow, sans the web UI. When it comes to hackathons, I'm the guy with the boring CLI app. The world of front end frameworks is overwhelming, and I'm really not sure what I should start learning. I don't much care about fancy optimized UIs, just the know-how of how to build simple web UIs talking to a REST interface, for example. Another dimension to showcase my work, besides the CLI. I'd appreciate any pointers to resources or advice.

Thanks a lot in advance.
