Svelte and Sveltekit are great in many ways. However, if you need to support legacy platforms with Sveltekit, you're in trouble, due to this issue: github sveltejs/kit/issues/12. The package @vitejs/plugin-legacy is no longer supported. Maybe it will be fixed some time in the future, but judging from the conversation in the ticket, it might take a while. Just saying, so you don't start a project, like I did, just to eventually find out you can't use the framework...
