This example isn't comprehensive, so you can't just copy and paste. However, it should be a good template to base your own solution off. I chose to use React but you can use any framework.
Note: Sentry has a Vite plugin. As of Astro 1.9.0, Astro runs Vite plugins twice during the build process, which results in map files being submitted twice. Until this is resolved, it doesn't seem like an acceptable solution.
