Updates? (Deps, Electron, Svelte)

[fire17]

Hi there! First of all thanks for the great repo! (still working fine)

was just wondering, if since this was made (2 or 3 years ago) there have been important changes or updates that should be made

this can be either for electron or for svelte and also mainly to update dependencies

Wondering if you can give that a look :) Thanks a lot and all the best!
