Yeah, I built this to do all the calculations on the front end and it’s too much. Takes too long to download the data (a few minutes) and too long to calculate all the scores (maybe 30-60 seconds). The best solution is to do them ahead of time on the back end. So that’s the next step in the project. I think what makes the most sense is for a relay (maybe a personal one, maybe a third party service) to do the calculations and store them for you, ready for quick access when they’re needed. Right now, that would mean maybe 30k or 40k pubkeys with a nonzero grapevine WoT score.
