Check if Astro is running in development

[past echo]

I'm sure there are several ways to check if Astro is running locally or in development but wanted to see what the easiest way is.

The reason for this is I have some 3rd-party scripts that don't work on localhost so want to disable those in dev.

There's a few ways you could do that. If your imports are in an .astro file, you could use import.meta.env.mode or similar variables provided by Vite https://vitejs.dev/guide/env-and-mode.html#modes
