Each instance owns one boolean at `toggle:.value` and stays synchronized across clients through named Server-Sent Events.\n\n## Files\n\n| File | Purpose |\n| --- | --- |\n| `index.tsx` | Toggle routes, rendered button fragments, Yjs mutations, SSE synchronization, and exports. |\n| `toggle.meta.tsx` | Machine-readable contract plus the handler and metadata UI mounted at the component root. |\n| `README.md` | Usage and endpoint reference. |\n| `template.tsx` | Parked fragment/template experiment; it is not mounted by `index.tsx`. |\n\n## How it works\n\n1. `GET /` renders the component metadata UI with interactive GET routes.\n2. `GET /list` reads existing `toggle:*` maps from Yjs and returns their instance names as autocomplete options; it never seeds instances.\n3. Choosing an instance on a parameterized GET route uses htmx path parameters to open that example.\n4. `GET /:instance` renders a persistent wrapper with one SSE connection.\n5. The wrapper loads either `/:instance/on` or `/:instance/off` based on the current Yjs value.\n6. Clicking the button posts the opposite route, which writes `value` and swaps only the button with `outerHTML`.\n7. Every real `value` change emits an SSE event named `on` or `off`, updating other connected buttons.\n\nNo transition logic or client-side state store is required.\n\n## Routes\n\nThe paths below are relative to the component mount point. In the combined gallery, the handler is mounted at `/toggle`.\n\n| Route | Behavior |\n| --- | --- |\n| `GET /` | Render the metadata UI with route controls. |\n| `GET /list` | Return a datalist populated from existing Yjs toggle instances. |\n| `GET /:instance` | Render the persistent htmx/SSE wrapper. |\n| `GET /:instance/on` | Wait until the value is `true`, then render the ON button. Optional `?timeout=ms`; default is 30 seconds. |\n| `POST /:instance/on` | Set the value to `true` and render the ON button. |\n| `GET /:instance/off` | Wait until the value is `false`, then render the OFF button. Optional `?timeout=ms`; default is 30 seconds. |\n| `POST /:instance/off` | Set the value to `false` and render the OFF button. |\n| `GET /:instance/stream` | Stream named `on` and `off` events when `value` changes. |\n| `GET /:instance/inspect` | Return the shared Yjs document as JSON for debugging. |\n\n## Composition\n\n```ts\nimport { handler as toggle } from \"./components/toggle\";\n\napp.route(\"/toggle\", toggle);\n```\n\nOpen `/toggle` for the component contract, or navigate directly to an instance such as `/toggle/job1`.\n\n## Standalone export\n\nThe default export is a fetch handler. Its root renders the same metadata UI.\n\n```ts\nimport toggle from \"./components/toggle\";\n\nexport default toggle;\n```\n\n## Dependencies\n\nThe parent Yjs factory provides:\n\n- `state(\"toggle\")` middleware for the instance map and long-poll helper.\n- `instancePath(c)` for mount-safe URLs.\n- `changes(map, signal)` for Yjs change observation.\n- The shared JSX renderer, htmx, SSE extension, Iconify, and Tailwind browser runtime.\n",[],[115,142],"50c582a3-a1a6-4c6c-8677-8613bbc316ef",["D",1783599528265],"deletedAt","legacyEnvVars","privacy","public","httpPrivacy","description","Component gallery: headless Hono SSR +
