SvelteKit 1.0 release blockers in Vite

[benmccann]

Update

Vite 2.7 fixed most issues that users faced. If you're having issues with a library please make sure you're using Vite 2.7. If you're still having problems, please file an issue

Describe the bug

SvelteKit apps are no different from any other Vite app from the most part. The unique things that they do are include vite-plugin-svelte and automatically add Svelte component libraries to optimizeDeps.exclude and ssr.noExternal (this latter functionality may be replaced with the experimental.prebundleSvelteLibraries option)

Blockers

vitejs/vite#2579 / vitejs/vite#3024 / vitejs/vite#3910 (prebundling skips .svelte) - experimental solution. see prebundleSvelteLibraries
vitejs/vite#7154 (externalizing of nested deps) - slated for 2.9
#3118 / #3053 (package.json issues) - fixed in 2.8
vitejs/vite#5890 (not externalizing dependency) - fixed in 2.7
vitejs/vite#3953 (resolving packages with exports) - fixed in 2.7
vitejs/vite#5446 (context="module" not scanned in separate scope) - fixed in 2.7
vitejs/vite#4425 (no main - only sub-directories exported. e.g. firebase) - fixed in 2.7
vitejs/vite#5197 (ESM-only deps) - fixed in 2.7
vitejs/vite#4306 (svelte store functions overwritten) - fixed in 2.6.11

vitejs/vite#4452 (resolve .cjs, .mjs) - fixed in 2.5.2

Nice-to-have

vitejs/vite#4192 (process.env on server) - fixed in 2.7
vitejs/vite#5193 (allow export default in template) - fixed in 2.6.8
vitejs/vite#5192 (better error messages for parse failures) - fixed in 2.6.4
vitejs/vite#4426 (surface package resolution failures) - fixed in 2.5.1, but partially rolled back (vitejs/vite#4873)
vitejs/vite#4699 (support application/ld+json) - fixed in 2.5
