You know, I wanted to have ServerMonitor as a PWA, since the project got started. Now, it is finally done and it feels awesome!
Converting a Flask application in a way, to make it usable as an Progressive Web App sounds not really hard, but it took me at least 3 hours to get everything working smoothly. A lot of problems I had were solved only because I brute-forced every idea I had to solve all these unsolvable bugs. This showed me once again, how important it is not to give up immediately. Sometimes, there is no solution on the internet and it's all up to you.
Try it out! Install the PWA!
