I use it on a simple website I built: https://covid19incharts.com https://covid19incharts.com This website fetches the Johns Hopkins University COVID-19 data from GitHub (in CSV files), and fetching this every single user action is not feasible. When a user first enters the website, this data is fetched from GitHub, parsed and formatted, and stored in IndexedDB (until it's deemed "stale"). I first used Local Storage, but I needed more space than most browsers allow on Local Storage, so I moved to IndexedDB. By the way, the API of IndexedDB is somewhat awkward, but there are great libraries like IDB (https://github.com/jakearchibald/idb https://github.com/jakearchibald/idb) that make it much more developer-friendly.
