11-06-2021 Deploying using Sapper vs SvelteKit
I recently started using Svelte, and wanted to try out using Sapper. This website is actually made using Sapper, and while I felt that the process from getting setup to deploying to be relatively smooth.
However, the Svelte team announced that they will stop improving Sapper, as they are allocating resources of their team to developing SvelteKit, which has been the new brain child to address the concerns and faults that Sapper was lacking in. Sapper after all was only a couple of years old.
UPDATE: At this point, SvelteKit is almost out of beta (supposedly), so as they migrate everything, you probably should take on Kit.
