Ask HN: Good Idea to Build Web Apps with Polymer Today?

I've inherited a Polymer application that is a little out of date and I've been coming up to speed on it and also looking at upgrade paths to the latest version.

The application isn't too big so migrating to something else would be possible and I'm trying to weigh my options here.

I'm hoping to hear from people who have built or currently developing Polymer applications and others who've investigated using it but decided against.

I have some concerns about continuing to use Polymer however because the documentation feels pretty bad, compared to other web frameworks. The testing suite they implemented I'm not sure really if it's stagnated or not (web-component-tester) and overall there doesn't seem to be a lot of development on Polymer in general.

I've heard a lot about web components and how "they're the future" talk on here, but I also only ever here Polymer mentioned when there's a web assembly or web components topic posted on here so the usage feels rather small (I've spent most of my time developing React applications for context).

I do really like how portable web components are. It's much easier to write up a web component than it is a react or vue component and the ability to port those around the application is very convenient.

Thanks for any feedback!
