We just announced this on Twitter but we are releasing a new

ViteStaticSite

construct. It’s a higher level CDK construct that makes it easy to create and deploy a Vite single page app. You can pass the environment variables from your backend to your frontend. And it also generates a type definition file, so your editor can autocomplete the environment variables for you! https://docs.serverless-stack.com/constructs/ViteStaticSite
