I had this issue with sveltekit trying the host option of vite running with bun.
The solution was to re-do the lock files.
You have to delete them and the node_modules folder.
Then you can npm install.
I am mostly a backend dev and I brushed up on my front end skills a <2 years ago since I had fallen behind and things looked like they were stabilizing. I learnt Vue and React, and used them in some personal projects. The job I got after adding these skills to my resume is at a company that still uses an ancient version of angular, but IDC either way since I rarely do front end.
Now, what in god's name are sveltekit, vite and bun? Actually, no, don't answer that, I can Google it. But please let me know if they are stable stuff that I should bother learning or if I can just wait for another year or two till everyone else figures out what is needed.
Sveltekit is the fullstack/SSR version of svelte (like next is for react or nuxt is for vue).
I reckon learning one of them might be helpful to learn component-based SSR and its benefits, personally I do think they have a firm place in the future of webapps.
Vite I can highly recommend, it's the best, fastest and least fussy bundler/builder I have ever used hands down (having used webpack briefly and packer for a while). Has some great features and is less of a pain to configure and get to work in my experience.
