# Env Vars Editor

> The environment variables editor from a deploy dashboard. Names clean themselves to UPPER_SNAKE and flag clashes in the same environment; values stay masked with a reveal, and sensitive ones lock for good once saved. Chips set each row's environments. Paste a whole .env into any name field, or drop the file, to import it. Remove with undo, filter by name, and save with ⌘S.

## Install

One-time setup (needs a subscription):

1. Add the registry to the project's `components.json`: `{"@assembli":{"url":"https://www.assembli.design/r/{name}.json","headers":{"Authorization":"Bearer ${ASSEMBLI_API_KEY}"}}}` (merge into `"registries"`).
2. Put an API key from https://www.assembli.design/account in `.env.local` as `ASSEMBLI_API_KEY=asm_…`.

Then install with the shadcn CLI (writes `components/env-vars-editor/env-vars-editor.tsx` and installs dependencies):

```bash
npx shadcn@latest add @assembli/env-vars-editor
```

Registry item JSON: https://www.assembli.design/r/env-vars-editor.json (send `Authorization: Bearer <api key>`)
