Framework to develop a quick CRUD frontend for an API

I have an rather simple API that has GETs PUTs DELETEs and POSTs. I need a simple web front end for this API and I wondered what people would recommend?

I don't need it to be pretty, just functional. I tried to use React but I think it is overkill for what I want to do and I got fed up of the huge ecosystem or yarn, npm, webpack, babel, scss and all that to create a simple web site.

Is there a framework that is more suitable for rather basic API based admin systems or should I just create some pages with Bootstrap?

I thought this would be easier than it turned out to be and I need some guidance.

Thanks!
