Add a class which applies display: none to badges we don’t want to see. This is accomplished by passing a `shouldDisplay` function along with each badge, which pulls the current query through a closure and applies it.
A bit roundabout, but it works.
The rest of the changes are refactors to avoid code duplication.
I decreased the debouce rate to 50, which seems to work well.
Fix#1314
I rewrote the frontend in React using a module bundler. It's matched feature-for-feature with the current frontend, with only slight changes in the styling. I did not fuss about making the styling identical; the badge popup looks particularly different.
This makes the front end much easier to develop. I'm really looking forward to implementing #701, to which this paves the way.
This makes light use of Next.js, which provides webpack config and dev/build tooling. We’ll probably replace it with create-react-app or our own webpack setup because unfortunately it comes with a lot of runtime overhead (the build is 400k).
