Is there a way to switch to deploying my sveltekit project via wrangler (version doesn't matter). Developement testing could be faster if I didn't wait for the git to deploy.

You can deploy to a git project via direct upload, using

wrangler pages publish <directory>

, for example, something like

npm run build && wrangler pages publish .svelte-kit/cloudflare

. If you just want to develop though, you should really be using local dev, not making deployments for both. Sveltekit I believe is

npx wrangler pages dev --proxy 3000 -- svelte-kit dev
