Earlier quoted context omitted.
Thanks! Tried it a bit and thought: "Hmm.. it's probably react that causes all these spinning "loaders" everytime I click somewhere. Wouldn't it be better without?". How do you see that? EDIT: Ups, why the downvotes? With spinning "loaders" I mean the "loading" animation the website shows. The spinning circle. Anything bad about this question?
The loading spinners happen when data is being fetched from the database. The app itself is downloaded upon initial load and anything from the database will trigger a loading spinner as it's being fetched.
Is the time the spinners run determined by the time the server needs to deliver the data? Would they go away when you put the site behind a CDN that delivers the data faster?
