I'm not sure I follow exactly, but if I understand you mean that when the database file is updated that the app updates? Right now on app load it updates the service worker and shows the files in cache first. If there's a newer file it fetches it in the background, it then sends a message to the client that there is a new file. I haven't implemented the next part yet but it should be able to invalidate the current file and load the new file without refreshing the page. Right now the new files will load the refresh after the new service worker is activated.

But the page still had to be refreshed to load the new service worker. I'm looking into ways to cut the time to loading the new files down because right now you have to refresh the page 3 times for the new files to take over.

The .peak files aren't designed to be a database that you can just add to during runtime, they're rather static and highly efficient in that context. But it's easy to edit the source files and generate a new .peak file from that.

You can take a folder of any kind of files and run peakgen on it and it will create a compressed .slab file that you can search and fetch results from just like the .peak files. I first saw that done with SQLite and I really liked it, so I knew I could do it too.
