No Environments Empty State Block for React

Nothing. The environments and variables are text in the page's state and a reload clears them. Values are not encrypted or hidden here, so never type a real secret. To wire it for real, create the environment with your API where the code says so, store each variable on your server, and show masked values in your own list.

The slabs stack, so the demo builds them from the bottom: Development, then Staging, then Production. The button's label always names the next one, and once all three exist it becomes a quiet, unavailable button that says so instead of disappearing, so focus never falls out of the page. Start over dashes the slabs again.

The key is shown in capitals and digits and underscores only; anything else is stripped as you type. A key must be new in the environment you pick, a value cannot be empty, and a demo environment holds four variables. A refusal says why in the line at the foot and, for a missing or repeated key or value, puts focus on the field to fix. Each variable adds one to the count on its slab's line, which is the list's way of saying what the drawing shows.

All three environments, with the ones that do not exist yet unavailable. When you create an environment, it becomes the one the next variable goes to. It is a native select, so it opens the system's own list on a phone.

No. It is hidden from assistive technology; the list beside it says which environments exist and how many variables each holds. The slabs are one SVG whose classes change, so a dashed slab fades into a solid one with a CSS transition that is off under reduced motion.

The slabs sit above the message at 160 px tall, the list under them, then the message and the button, then the variable row in two columns. The panel is as tall in every state, so nothing jumps while you create and add.
